论明代滇僧游参内地活动及其历史影响

佛教是明王朝在西南边疆进行文化经略的重要切入点。明太祖制定的佛教政策直接或间接推动了汉传佛教在云南的传播。洪武时期,官方出于经略西南的政治考量,认可和支持滇僧到内地的游参活动,将元代已有的滇僧内地求法巡礼活动予以制度保障与政治便利。明代滇僧游方省外,求法、弘教于内地,这种跨省域佛教交流推动了汉传佛教在边疆地区的发展,云南丛林也藉此构建并强化了与明廷的政治联系及与内地的文化联系,折射出明代边疆民众对内地文化认同不断强化的历史趋势。

Rural Tourism Format Network Mode Based on Community Participation:A Case Study of Jindatian Village of Zhejiang Province

Because of the existing problems, features and demands in China ’s rural tourism development, sustainability in modern rural tourism necessitates the own ca-pability of rural vil ages and the active participation of community residents. The structure of rural community with the impact of rural tourism is analyzed, and the coupling relation between rural tourism development mode and rural community is discussed. With the integration of rural tourism resource and community capability, network of rural tourism formats is organized starting with the possibility and ways of participation of community＆#39;s vil agers, and formats of public resource type, plat-form investment type, smal and micro enterprises type, and general investment type are constructed to realize the positive cycle of rural community factors and tourism development. A case study of Jindatian Vil age demonstrates the feasibility of rural tourism network mode based on community development, which can depend on community＇s capability to realize the sustainable rural tourism, the protection and heritance of rural culture, and the regeneration of rural economy.

Design Guide for Playgrounds

Children, who are the most weak people about sensibility and telling their desires clearly, act differently at every age phases. Because of this, child oriented designs must appeal to children about whole ages and features. Playgrounds are places where children of all ages and features spend their times commonly. But when these playgrounds were observed, that can be seen, playgrounds can not meet children＇s need and, because of this, they become quitted places. Within this article, child, play and playground concepts have been examined and the parameters of playground design have been classified. The aim of article is revealing the parameters for playgrounds design and offering a guide so that it can give an idea for the new- designs.

Reflections on the Connotations of Ecotourism

As the most desirable option for sustainable development of tourism industry, ecotourism still suffers from lack of a clear-cut and widely accepted definition, posing many risks and threats in its practices. Based on collection and collation of various concepts and explanations of ecotourism both at home and abroad, this paper reflects on the current connotations of ecotourism in terms of four aspects, namely, objects of ecotourism, ecotourists, nature of ecotourism as well as the relationship between ecotourism and communities. In-depth analysis was performed in an effort to revise the misinterpretation of ecotourism and provide implications for ecotourism initiatives. The main conclusions and fruits of this article include： 1） The objects of eeotourism should go beyond natural, pristine, or even only primitive natural areas to including cultural resources together with their natural context which also deserve preservation. 2） Tourism operators, compared to tourists, have more leverage and hence should shoulder more responsibilities for conservation. 3） Ecotourism should serve as a principle to guide tourism initiatives towards sustainability, rather than merely a special tour package. 4） The theoretic foundation was laid for community participation in ecotourism.

Factors That Influence Local Community Participation in Tourism in Murchison Falls Conservation Area

Community＇s participation is fundamental in understanding the factors that influence their access to and utilization of tourism resources. It is a plausible way of involving local communities in the planning and management of the available resources for their sustainability. This study examined the socio-economic characteristics of the households in Murchison Falls Conservation Area to understand how they influence their participation in tourism and eventually enhance household welfare. Using household survey and key informant interviews, data were collected on demographic and socio-economic characteristics of the respondents and analyzed using Binomial Logit Regression in order to show the factors that influence participation of households in tourism. It was found that the households＇ characteristics significantly influenced their participation. In particular, level of education （r = 0.824）, engagement in farm labor （r = 0.651）, provision of services to the tourists （r = 0.841）, income （r = 0.83） and landholding （r = 0.689） significantly influenced households＇ participation in tourism. On the other hand, age （r = 0.59） and period of residence （r = 0.430） did not significantly influence the households＇ participation in tourism. These results suggest that a clear understanding of the households＇ socio-economic characteristics is a vital step in engaging them meaningfully in tourism activities meant to enhance their livelihoods. Equally important is the need for tourism managers and local government leaders to consider these characteristics when designing policies and strategies to enhance community involvement and management of tourism at a conservation area level.

Chlorophyll a and Trophic State in the Boka Kotorska Bay （Eastern Adriatic Sea）

The monthly changes in chlorophyll a, phytoplankton abundance and physicochemical parameters at two stations in Boka Kotorska Bay were investigated between 2003-2004. Nutrient salts varied widely, with maximum 3.65 μmol.L^-1 for nitrates and 0.23 μmol.L^-1 for phosphate. Chlorophyll a concentration ranged from 0.25 to 7.63 mg·m^3 and the highest value was measured in winter period of year. It seems that reason for this is the land-based nutrient input into the coastal area here. According to chlorophyll a, nitrates and phosphates concentrations, the area could be oligomesotrophic to mesotrophic during winter.

Hydrographical parameters and phytoplankton assemblages along the Pondicherry—Nagapattinam coastal waters,southeast coast of India

Hydrographical parameters and phytoplankton assemblages were determined along the Pondicherry, Parangipettai and Nagapattinam coastal waters, southeast coast of India. All the hydrographical parameters such as sea surface temperature, salinity, p H, total alkalinity, dissolved oxygen and nutrients like nitrate, nitrite, inorganic phosphate and reactive silicate, chlorophyll a and phytoplankton assemblages were studied for a period of five months(May, August, September 2010, March and November 2011). Over 121 species of phytoplankton represented by 93 species of diatoms, 16 species of dinoflagellates, 9 species of blue-green algae, 2 species of greens and 1 species of silicoflagellate were recorded. High phytoplankton species diversity was found in March 2011 when salinity and nitrate concentrations were low and reactive silicate and inorganic phosphates were moderate. Species diversity was low during May 2010 when increased sea surface temperature, salinity and low nutrients availability were observed. Coscinodiscus centralis, Diatoma vulgaris and Proboscia alata were dominant, especially Coscinodiscus sp. distributed in all stations whereas Skeletonema costatum, Odontella sinensis and Ditylum brightwellii were abundant in August and September 2010. From principal component analysis and multiple regression analysis, it is evident that variables like sea surface temperature and dissolved oxygen are the most important factors influencing the seasonal pattern of phytoplankton population.

Characteristics of the δ15NNO3 distribution and its drivers in the Changjiang River estuary and adjacent waters

In this study, we conducted investigations in the Changjiang （Yangtze） River estuary and adjacent waters （CREAW） in June and November of 2014. We collected water samples from different depths to analyze the nitrogen isotopic compositions of nitrate, nutrient concentrations （including inorganic N, P, and Si）, and other physical and biological parameters, along with the vertical distribution and seasonal variations of these parameters. The compositions of nitrogen isotope in nitrate were measured with the denitrifier method. Results show that the Changjiang River diluted water （CDW） was the main factor affecting the shallow waters （above 10 m） of the CREAW, and CDW tended to influence the northern areas in June and the southern areas in November. 615Nrqo~ values in CDW ranged from 3.21%o-3.55%o. In contrast, the deep waters （below 30 m） were affected by the subsurface water of the Kuroshio Current, which intruded into the waters near 3 I^N in June. The ~iI^NNo3 values of these waters were 6.03%0-7.6%0, slightly higher than the values of the Kuroshio Current. Nitrate assimilation by phytoplankton in the shallow waters of the study area varied seasonally. Because of the favorable temperature and nutrient conditions in June, abundant phytoplankton growth resulted in harmful algae blooms （HABs）. Therefore, nitrate assimilation was strong in June and weak in November. The ~15NNo3 fractionations caused by assimilation of phytoplankton were 4.57%0 and 4.41%o in the shallow waters in June and November, respectively. These results are consistent with previous laboratory cultures and in situ investigations. Nitrification processes were observed in some deep waters of the study area, and they were more apparent in November than in June. The fractionation values of nitrification ranged from 24%0-25%o, which agrees with results for Nitrosospira tenuis reported by previous studies.

Modeling of Molecular Distillation Parameters： Case Study of Green Coffee Oil （Coffea arabica）

In principle, the free fatty acids, diterpene fatty acid esters and triglycerides from green coffee oil can be separated effectively, by a suitable separation process, due to the differences between molar mass and vapor pressures. In addition, in the case of component separation by molecular distillation, boiling point is replaced by evaporation rate at a given temperature. Several experiments and theoretical analyses have been carried out to identify the impact of important parameters （mean free path, evaporation rate, relative volatility and Knudsen number）, which determine the performance of these processes and degree of separation. In this work, a process development based on molecular distillation, for the enrichment of coffee diterpenes from green coffee oil is presented. The distillates were enriched in diterpene fatty acid esters and free fatty acids, while the residues were enriched in high molar mass triglycerides.

Zooplankton community of Keibul Lamjao National Park (KLNP) Manipur, India in relation to the physico-chemical variables of the water

Keibul Lamjao National Park （KLNP）, a floating park in Loktak Lake, Manipur （India） was studied from Winter （WIN） to Post Monsoon （POM） for its zooplankton composition and some selected water parameters. The resultant data were subjected to multivariate techniques---Principal Component Analysis （PCA） and Canonical Correspondence Analysis （CCA）. Analyses of water parameters with PCA revealed that the first PC axis （PC 1） accounts for maximum variance in the seasonal data, explaining a variability of 91%. The PCA revealed that the seasonal variability in water parameters was due to the wet and dry cycle of seasons and the stations were distinguished on the basis of transparency and turbidity. Zooplankton abundance was dominated by copepods followed by cladocerans. Temporally, abundance of copepods reached a maximum during Post-monsoon （POM） （3 880 ind./L）. Spatially, $6 was found to be most abundant of the other stations in zooplankton. Copepodites and nauplii larvae were the major components of zooplankton. The Rotifera were the least abundant among the three zooplankton groups. Brachionus formed the major component of Rotifera zooplankton at all the stations during the study period. In the Cladocera, Macrothrix was present during all the four seasons, while Pleuroxus, Oxyurella, Kurzia and, Diaphanosoma were rare. The CCA shows that maximal temporal variability in zooplankton abundance was explained by temperature and rainfall. ANOVA revealed no significant difference in mean zooplankton abundance among the seasons, but there was a statistically significant difference among the sites.

Local Community Participation in Homestay Program Development in Malaysia

The tourism industry is the second largest economic contributor in Malaysia, following the manufacturing sector. In 2008, recorded tourist arrivals reached 22.05 million and resulted in RM49.6 billion （USD13.4 billion） in revenue. The government has recognized the tourism industry in Malaysia as an engine for economic, social, political and ecological development, especially in rural areas. The Homestay Program is actively promoted by the Ministry of Tourism as a type of community based tourism in Malaysia. It is realized by the government as a catalyst for rural community development, particularly from a socio-economic perspective. The benefits of community based tourism can be further developed through the participation of women, youth and retired people. To realize the potential of the Homestay Program, the Malaysian Rural Tourism Master Plan 2001 was formulated. In the Malaysian Plan （2006-2010）, one of the points of focus by the government is on community development; rural tourism is one of the mechanisms. By June 2009, there had been 3,264 participants in 140 Homestays. Recently, the Ministry of Tourism has given the Homestay Program special emphasis. Under the 9th Malaysia Plan, a total of RM40 million was allocated to the ministry for upgrading infrastructure and facilities in participating villages. Developing the capabilities of local communities is an important component in ensuring the tourism development project benefits them; without supporting the communities in their endeavors, the physical development means nothing to them. If local communities are not equipped to actively participate, third parties could easily manipulate them, resulting in external domination of tourism development. Therefore, this descriptive study explores the motivation of local communities involved in the Homestay Program and the readiness among the local communities, as well as the appropriateness of training provided by government agencies aimed towards empowering local communities. Sixty-two respondents from local communities actively involved in operating the Homestay Program participated in this study. Respondents were from the district of Muar, Johore, Malaysia （Homestay Kg. Parit Bugis, Homestay Kg. Satang Buaya, and Homestay Kg. Melayu Baharu, Bt 28 Lenga）.

Tibetan Attitudes Towards Community Participation and Ecotourism

Some Tibetan villages in Shenzha county, Tibet were chosen as typical Tibetan communities in China. Attitudes and perceptions towards Tibetan community participation in ecotourism were analyzed using face to face interviews. Most residents supported the development of ecotourism. They are willing to engage in ecotourism projects and accept ecotourism education and training, and expect that the government provides opportunities for them to participate in making ecotourism decisions. Most residents believed that ecotourism promotes local economies and social development, and enhances the ability and quality of local residents while improving their environmental consciousness. However, some residents were concerned that ecotourism may destroy local natural environments and Tibetan folk customs and culture. The level of community participation in ecotourism development is only in its infancy in Shenzha, but there is strong potential. The chief participatory approaches of ecotourism development for most residents were providing labor and catering services and commodities for tourism, and Tibetan performance singing and dancing. Limiting factors include language, a shortage of knowledge and skills, and poor ecotourism infrastructure. Most residents had little confidence that the government was willing to support them to participate in ecotourism. We put forward some mechanisms to enhance the level of community participation in ecotourism in this important region.

The Study on Strategy of Sustainable Development in Coastal Tourism Resources from the Global Change Perspective

Global change is induced by human activities and these changes impact tourism development. The transportation system especial y aviation consumed by tourists and accommodation facilities in coastal destinations release massive greenhouse gases and contribute to global change. The ocean is very important to the society and the economy, and coastal tourism is one of the main human activities in the coastal zone. Coastal tourism resources are rich in China, and coastal tourism plays a decisive role in the marine economy. Here, we analyze problems and chal enges during the development of coastal tourism resources from the global change perspective, and identify key factors for the future and ecologically friendly coastal tourism resource development and management under the framework of sustainable development. Based on our ifndings we recommend changing the pattern and products of coastal tourism to develop low carbon coastal tourism based on the idea of“green thinking”;more attention on developments of creative tourism products such as ecotourism and alternative tourism;changes to coastal tourism resource utilization by developing low carbon coastal tourism, advocating carbon emission reduction, promoting carbon compensation and carbon economy, and encouraging new energy saving technology application. Stakeholders also need to be considered. All these measures should be implemented and optimized during the process of planning-management-monitoring-evaluation in the dynamic model. Due to limited data on coastal tourism resource development and management in the global change perspective, part of our reference data is from whole tourism research results and this is a shortcoming of our approach.

Value and Heterogeneity: Using a Choice Experiment to Evaluate the Coastal Recreational Environment

The management of the coastal park environment is a major ecological and economic development issue. In developing effective policies, relevant information is essential, especially the economic valuation of various recreation-related environmental attributes. This study used Dalian coastal parks as a pilot study area and estimated the willingness to pay(WTP) of tourists using three different discrete choice models. In this study, we analyzed the preference heterogeneity among the respondents regarding a combination of park attributes, and the individual respondent’s WTP values were estimated for each attribute. The results indicate that water quality amelioration and trash reduction had the highest economic values among the given attribute factors. In addition, the estimated tourist WTP varied considerably among different segments, such as among the visitors who preferred different recreational activities. These findings provide valuable information that will allow coastal park managers to develop policies which maintain a balance between tourism development and improvement of the coastal environment.

A new paleoenvironmental index for anoxic events—Mo isotopes in black shales from Upper Yangtze marine sediments

This paper investigates the high-solution of Mo isotopes and uses trace-element analyses for fresh and representative black shales and siliceous shales collected from the transition between the Late Ordovician and the Early Silurian at the Wangjiawan section in Yichang and the Late Permian Dalong Formation in the Shangsi Section of Sichuan. The applicability of different geochemical parameters used as paleo-oxygenation indices are also compared. The preliminary results show that V/（V＋Ni）, Uauth （auth U）, V/Cr, Ceanom and U/Th have a scattered variation range, but most samples plot within the suboxic-anoxic fields. The suboxic-anoxic environment was dominant during the deposition and formation of the two anoxic facies. These redox indicators show little correspondence to the δ98M0 values. The U/Mo ratio can be used as a potential proxy for the paleo-redox conditions due to the possibility that Mo is enriched relative to U at different redox gradients during early diagenesis. This evidence is more significant for the euxinicity condition and corresponds to positive δ98M0 （〉1.5%o） values with low U/Mo ratios. This evidence is likely related to the depositional conditions near the boundary between anoxic and euxinic environ- ments, which are characterised by low bioturbation or water circulation. Other samples reveal a wide scatter of U/Mo ratios and δ98M0 〈1.5%0. These results are likely due to punctuated improvements in oxygenation with intense bioturbation or water circulation, which led to the redistribution of trace element.
