Yunnan, the southwest part of China, is one of the birthplaces of humanity. It has beautiful sceneries, mysterious religious and national color, therefore, Yunnan is the assembly point for scholars and merchants since ancient times. Because of adjacent to Vietnam, Burma and Laos, the traditional culture of Yunnan is exotic as well. Its tourism is more developed than ever, although some parts of it are still in poverty. We should lay the key point of construction in Yunnan if we want to balance the developments of regions. Based on Yunnan’s geographic features, and then strengthen the investment to Yunnan region, the development of Yunnan will be improved. It is wise to choose the Silk Road to promote the development of sport tourism in Yunnan. In the ancient, there was East European and Eurasian Silk Road that lay the China’s economic development of the tone. Today, with the rapid development of China’s economic, the southwest Silk Road could improve its development, which will achieve the multiple developments in economy, culture and society. This article will elaborate on the related strategies on how to improve the development of sport tourism by developing the Silk Road in Yunnan province, and to sum up the effective strategies of it. 展开更多

Modem tourism development to the present, the tourists are not pursuing the general sense of the mountains and rivers, but the pursuit of harmony between man and nature, unity and the challenges of the nature in order to return to nature, fitness and leisure. Under this condition, this paper proposes the model of construction of sports tourism system in Yunnan province under the core background of Silk Road. The research results of the sports tourism theory and practice have played an important role in promoting the development of sports and tourism. But the concept of sports tourism, different opinions, there is still no unified understanding, especially for the tourism sports research is rare. Our research provides the novel perspective on the solutions to the Yunnan sport travelling that will promote the development of the related subiects. 展开更多

The present world pattern has undergone major changes,the trend of world multi-polarization is constantly emerging,and peace and development remain the main themes of today’s society.The formal signing and implementation of the Regional Comprehensive Economic Partnership(RCEP)is important for meeting the needs of peace and development of many countries and regions.China is in a new era of reform and opening-up,and the RCEP content is in line with China’s concept of pursuing a path of rejuvenation.Based on the locations of important borders,Yunnan Province has become one of the key places for China’s opening-up and development regarding Southeast Asia and South Asia,and the high-quality development of its tourism service trade is of great significance.This study first used the grounded theory analysis method to organize,analyze and process the records of international conferences and government press conferences held in Yunnan Province,as well as important related issues since the signing of RCEP.Then,the social network analysis method was used to analyze the social recognition degree of RCEP in promoting the high-quality development of the tourism service trade in Yunnan Province from the perspectives of different levels and group consensus.The results show that cooperation is the key macro driving force for RCEP in promoting the high-quality development of the tourism service trade in Yunnan Province.Regarding the opportunities and environment of the transportation dividend,policy dividend and investment dividend,port construction,border township construction and exhibition-related construction are important cooperation contents,so they are conducive to the recovery of the tourism industry in a broader development space.Competition can improve the driving force of RCEP in promoting the high-quality development of the tourism service trade in Yunnan Province at the micro level,and has more practical significance.For example,RCEP can better rely on its own geographical advantages and international market competitiveness,optimize the use of resources inside and outside ports,and use high-tech products to form a more green,ecological,organic and sustainable development.In different levels of social identity,RCEP’s power of cooperation is more strongly recognized,while the power of competition is less recognized.However,from the perspective of grouping the various groups,RCEP’s powers of cooperation and competition are jointly recognized by the other groups,indicating that cooperation and competition are necessary for the realization of RCEP’s power.The results of this study provide a certain reference for understanding the dynamics of RCEP in more detail from more angles and for the local implementation of RCEP rules and measures. 展开更多

Monitoring and minimizing tourist’s water consumption is essential for the sustainable development of mountain destinations in the world. However, available data and a generally accepted protocol on such measurement are still limited. This study uses water footprint accounting to quantify tourist’s water demand in the Liming valley, a World Heritage site and a rapidly growing tourism destination in Northwest Yunnan, China. Both the water for direct and indirect use is taken into account based on the consumptive behavior of the tourists in the valley. Data were collected through guesthouse monitoring and a tourist survey in the 2005 tourist season. The results indicate that an average tourist leaves behind a footprint of 5.2 m3 on local water resources per day. Food production and waste dilution are the two most important water consumption factors. The results also show tourists consume more water than the local residents on per capita basis. This suggests more commitment is necessary to cope with this stress by individual tourists. Management implications to make water use more sustainable in mountain destinations are derived from this study. 展开更多

The study of seismic attenuation property is a major subject in seismology. Seismic waves recorded by seismic stations (seismographs) contain source effect, seismic wave propagation effect, site response of seismic stations and instrumental response. The path effect of seismic wave propagation, site response of seismic stations and instrumental response must be taken out in the study of source property with seismic data. The path effect of seismic wave propagation (seismic attenuation) involves an important influential factor, the anelastic attenuation of medium, which is measured with quality factor Q, apart from geometric attenuation with the distance. As a basic physical parameter of the Earth medium, Q value is essential for quantitative study of earthquakes and source property (e.g. determination of source parameters), which is widely used in earthquake source physics and engineering seismology. 展开更多

The Jinman deposit is a Ag-bearing copper vein deposit located at the north marginof the Lanping-Simao back-arc basin in West Yunnan. Systematic studies of fluid inclusions andstable isotopes are presented in this paper. The filling-replacement stage and the boiling-exhala-tive precipitation stage of mineralization took place at T1 = 140 - 280℃ and T2 = 94 - 204℃under pressure of (600 - 1200) ×105 Pa. The salinity of ore-forming solutions ranges from 5 wt%-20. 8 wt% (NaCl). Sulphide δ34S(CDT) values are in the rang of - 9.6‰ - + 11.03% witha range of 22. 66‰ showing an apparent "pagoda"-shaped distribution in histogram. Mean-while, the δ34S values of the various sulphides are consistent with the characters of isotope equi-librium fractionation, i. e., δ34SPy>δ34 SCp> δ34SBn. The TS/TOC ratios of the ores are widelyvariable between 0.16 and 5. 54 with no correlation of any kind can be established. Accirding to themodel of Ohmoto, the oxidation-reduction ratios of sulfur species in ore-forming solutions at the twomineralization stages were calculated to be R’1 = 2. 16×10(-17) and R’2 = 1. 55×104. δ13CCO2 (PDB)values obtained from fluid inclusions in calcite and quartz are between - 8.12‰ - - 3. 18‰, av-eraging - 5. 26‰, which are comparable with the isotopic composition of mantle-derived CO2.Inclusions in quartz yield δ13CCH4(PDB) between - 32. 11‰ and - 22. 04‰ (averaging- 26. 69‰),similar to that of methane in modern geothermal gases. For the ore-forming soutions, δ18OH2O(SMOW) values are between - 10. 57‰ and + 9. 77‰ and δDH2O(SMOW) are between - 51‰and - 135‰. Considering the effect of isotope exchange during waterrock reactions, most ofthe data are plotted along or close to the line defined by the reaction of meteoric water withclastic rocks, while a small part of the points fall near the reaction line of magmatic water withclastic rocks. In δ13C vs. δ18O diagram, the ore-forming soutions are plotted for the most partinto the mixing area between the meteoric fluid and the deep-seated fluid and partially on themixing line of P = 1. 展开更多
