Influence of Human Activity Intensity on Habitat Quality in Hainan Tropical Rainforest National Park,China

Due to long-term human activity interference,the Hainan Tropical Rainforest National Park(HTRNP)of China has experienced ecological problems such as habitat fragmentation and biodiversity loss,and with the expanding scope and intensity of human activity impact,the regional ecological security is facing serious challenges.A scientific assessment of the interrelationship between human activity intensity and habitat quality in the HTRNP is a prerequisite for achieving effective management of ecological disturbances caused by human activities and can also provide scientific strategies for the sustainable development of the region.Based on the land use change data in 2000,2010,and 2020,the spatial and temporal variations and the relationship between habitat quality(HQ)and human activity intensity(HAI)in the HTRNP were explored using the integrated valuation of ecosystem services and trade-offs(InVEST)model.System dynamics and land use simulation models were also combined to conduct multi-scenario simulations of their relationships.The results showed that during 2000–2020,the habitat quality of the HTRNP improved,the intensity of human activities decreased each year,and there was a negative correlation between the two.Second,the system dynamic model could be well coupled with the land use simulation model by combining socio-economic and natural factors.The simulation scenarios of the coupling model showed that the harmonious development(HD)scenario is effective in curbing the increasing trend of human activity intensity and decreasing trend of habitat quality,with a weaker trade-off between the two compared with the baseline development(BD)and investment priority oriented(IPO)scenarios.To maintain the authenticity and integrity of the HTRNP,effective measures such as ecological corridor construction,ecological restoration,and the implementation of ecological compensation policies need to be strengthened.

A scenario-based clean diesel production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels, China National Petroleum Corporation （CNPC）, the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the output and emission related properties, including cetane number, and sulfur and aromatics contents of diesel produced by CNPC, will vary with changes in the configuration of diesel production units in the next 5-10 years. The results showed that, to upgrade its diesel, CNPC needs to adjust its diesel pool by decreasing the share of fluid catalytic cracking （FCC） diesel and increasing the shares of hydrocracking （HDC） and hydrotreating （HDT） diesel. Furthermore, to produce ultra-low-sulfur diesel, straight-run diesel as well as poor diesel blendstocks such as FCC diesel and coker diesel should be hydrotreated before being blended into finished diesel. Developing highly efficient HDC and HDT catalysts and corresponding processes is the key to CNPC economically producing more and cleaner diesel.

Effects of China's National Essential Medicines Policy on the Use of Injection in Primary Health Facilities

The overuse of injection exists more than 20 years since economic reform in China.It is a persistent problem and seems becoming a new challenge in the new health reform period.This study was designed to assess the effect of national essential medicines policy(NEMP) on injection use at primary health facilities in China by investigating their prescription information.Questionnaires were designed and disseminated to collect empirical data on injection use at 120 primary health facilities in 6 provinces from January to September in 2010 and 2011.The injection use was measured as the indicator as the percentage of prescriptions with one or more injections.The results showed that the percentage of prescriptions with one or more injections was decreased from 38.91% to 36.82%(2 =11.158,P=0.001) in the all survey areas during the NEMP reform.The difference in level of the injection use in 2011 was significant among the eastern,central and western regions(2 =223.584,P=0.000);level of the injection use in western region was the lowest(27.73%),while that in the central region was the highest(43.10%).The level of the injection use in 2011 among different provinces was also of great difference(26.00%-58.25%,range:32.25%).The level of the injection use in 2011 was still much higher than the standard suggested by WHO for developing countries(13.4%-24.1%).It was concluded that NEMP has improved injection use in China,but the injection abuse situation remains serious,indicating that one of the priorities to the next stage of NEMP is to promote the rational use of drugs,especially the injection use.

A scenario-based clean gasoline production strategy for China National Petroleum Corporation

Facing increasingly strict environmental regulations on transportation fuels, China National Petroleum Corp. （CNPC）, the second largest supplier of petroleum products in China, needs to upgrade its transportation fuels. Using the scenario-based analysis method, this paper analyzes how the emission related properties, including antiknock index, and sulfur, olefin, benzene and aromatics contents of gasoline produced by CNPC, vary with the change in the configuration of gasoline production units in the future 5-15 years. The results showed that for CNPC to upgrade its gasoline, the share of fluid catalytic cracking （FCC） naphtha must be reduced, but just increasing reformate or alkylate and isomerate will result in excessive increase in benzene and aromatics contents or a great loss of gasoline octane number. Therefore, CNPC should suitably control the capacity of its FCC units and increase the capacity of reformer, alkylation and isomerization units. Most importantly, CNPC should dramatically expand the capacity of its hydrotreating or non-hydrotreating gasoline upgrading units to decrease the olefin and sulfur contents in FCC gasoline that takes a dominant share of about 80% in the gasoline pool of China.

Valuation of forest carbon sinks in China within the framework of the system of national accounts

To better promote forest resource management and strengthen the development of forest carbon sink marketization, this paper studied the accounting of forest carbon sinks from 2003 to 2008 based on a system of national accounts （SNA） and data from the latest forest resources inventory in China. The study calculated the value of forest carbon stocks at a total of RMB 817.13 × 10^9 yuan in 2003 and RMB 839.93×10^9 yuan in 2008, with an average annual increase of 0.55 % from an increase in physical carbon sinks. The total value of forest carbon sinks in 2003 and 2008 was RMB 26.73×10^9 yuan and RMB 29.77×10^9 yuan, respectively, with an average annual growth of 2.18 %. From 2003 to 2008, both stock and flow value of forest carbon sinks increased, but the total net flow value of carbon sinks decreased. The growth rate for the environmentally adjusted Gross Domestic Product （eaGDP） for China＇s forest carbon sinks was 17.23 %, outstripping the average growth rate of 9.5 % for the GDP during the same period. The study alsoindicates that China＇s forest carbon sinks affects the GDP in the range of 0.25-0.26 %, and its economic potential is not relatively huge.

Seed Germinability of 23 Crop Species After a Decade of Storage in the National Genebank of China

Seed viability of 18 576 accessions of 23 crops was monitored. After 10-12 years storage in National Crop Genebank ofChina (NCGC), more than 96.12% of the accessions maintained high germination percentage (>85%). The germination of95 accessions, accounting for 0.51% of the total, declined significantly from above 80% to below 70%. For each crop ofcarrot (Daucus carota var. sativa DC.), lettuce (Lactuca sativa L.), cotton (Gossypium sp. L.), flax (Linum usitatissimumL.) and castor-oil plant (Ricinus communis L.), the mean monitored germination percentage declined significantly as awhole, of which carrot and lettuce seeds lost viability more rapidly. Seed initial germination percentage and pre-storageenvironments affect subsequent seed viability in storage.

Tourist Behaviors in Wetland Park:A Preliminary Study in Xixi National Wetland Park,Hangzhou,China

Public education as well as tourism and leisure are the two important functions of national wetland park, and tourist behaviors act as the guiding factor in the national wetland park construction and management.As the first national wetland park in China, Xixi National Wetland Park, located in Hangzhou City, Zhejiang Province, will give constructive instructions to the construction and management of other wetland parks and ecotourism resorts.This paper analyzed the tourist behaviors in Xixi National Wetland Park.By the observation, in-depth interview and questionnaire, the results show that tourists in wetland parks are different from those in the other common destinations, and they are also different from those strict eco-tourists.In fact, the tourists in wetland park have unique characteristics, such as the intense perception to the functions of wetland ecosystem and the environment impact behaviors.Those tourists are preferred to natural landscapes in their motivations and expectations.Wetland landscapes are the main image to those tourists in the Xixi National Wetland Park.Tourist expectation, experience and satisfaction are all critical factors for the success of the planning and management in national wetland parks.Based on the results, some measures for the sustainable development of wetland parks, including to optimize wetland theme landscape and tourism products, to improve tourist facilities and services, to enhance quality of visitor experiences, and to implement total quality management based on tourist characteristics, are given to national wetland park ecotourism.

Analysis of structural characteristics and spatial distribution of the national intangible cultural heritage in China and its policy implications

Based on an investigation of four published batches listing 3, 140 national intangible cultural heritage(ICH) projects in China and using GIS and some quantitative analysis methods, the spatial structure was investigated and the characteristics and distribution discussed. The distribution of ICHs in China is agglomerative and spatially dependent. From the view of ICH type, each type is distributed in different places, for different reasons, with history being the most important one we found. Nationwide, high-density cores are located in the Beijing-Tianjin-Hebei region and the Yangtze River Delta region. High densities of ICH are concentrated in flat, water-rich regions where broad-leaved forests dominate plains and low mountain areas-areas that have fertile soil, pleasant weather, a long history of culture, ethnic agglomeration, and development. This paper suggests that development of the ICH should be based on discovering unknown items, to break the existing pattern of strong cohesion and high density, and to seek a balanced development of the whole.

Protecting the national parks and the world heritage sites in China: challenge and strategy

About 70% of its land area as mountains and plateaus, China is the largest mountain country in the world. Thanks to its vast territory (9.6 million km2), outstanding relief and varied climates, China boasts extremely plenty of ecosystems and landscapes. From south to north, it traverses almost all the temporal zones from tropical rainforest in the southernmost to frigid-temperate needle-leaved forest in the northernmost; from east to west, it sees a gradual transition fro humid forest landscape to extremely arid desert landscape; vertical change of landscapes is most striking owing to the existence of many high mountains (above 6000-7000 m, e.g., the Himalayas, the Kunlun, the Tianshan, the Hengduan, etc.) and plateaus, especially the immense Tibetan Plateau (averagely 4500 m above sea level). All of this give rise to the richness and diversity of ecosystems and landscape in China. Some of the ecosystems are endemic to China, e.g., alpine desert and alpine steppe in the Tibetan Plateau. As a result, China bears a great responsibility in the protection of global ecosystems and landscape.

Evaluation of nest site preferences of a nest dismantler,the Hair-crested Drongo(Dicrurus hottentottus) in Dongzhai National Nature Reserve of central China

Background:The Hair-crested Drongo(Dicrurus hottentottus) exhibits a unique nest-dismantling behavior after the fledging of the young.One hypothesis explaining this behavior is dismantling one's own nest may reduce potential competition for nest sites in the following breeding season because suitable breeding habitat might be limited,and sites are often reused.Methods:By comparing the habitat features at nest and random locations,we determined the nest habitat preference of the Hair-crested Drongo within Dongzhai National Nature Reserve,Henan,China.We also compared habitat features with nesting success to determine if any trends could be detected.Results:We found that nest tree height,diameter at breast height,live crown ratio,tree rank,and presence of overstory were significantly higher at nesting locations than random locations;slope,leaf litter cover percentage and depth,presence of understory and midstory,and number of trees per hectare were significantly lower at nest sites than random sites.Drongos preferred to use some tree species,such as Metasequoia glyptostroboides,Castanea mollissima,and Pterocarya stenoptera for nesting.Failed nests were often associated with habitat with higher percentage of leaf litter on the ground.Conclusion:Our data support that selection of nest sites does occur for this species at this site and therefore support the hypothesis that breeding habitat limitation could be one of the driving forces for the development of the nestdismantling behavior in this species.

The Epidemiological Characteristics of Beijing Lineage Mycobacterium tuberculosis from a National Referral Center in China

Our study was to investigate the epidemiological characteristics of M.tuberculosis from a national tuberculosis referral center in China. All strains isolated from TB patients, were genotyped by the RD105 deletion, 8 and 51 SNP loci and VNTR. The high differentiation SNPs of modern Beijing strains were analyzed for protein function and structure. 413 M. tuberculosis were included. Of 379 Beijing lineage M. tuberculosis, ＇modern＇ and ＇ancient＇ strains respectively represented 85.5% （324/379） and 14.5% （55/379）. Rv2494 （V48A） and Rv0245 （Sl03F） were confirmed as high differentiation SNPs associated with modern strains. In a word, Modern Beijing lineage M.tuberculosis was dominant and the structural models suggested that modern sub-lineage may more easily survive in ＇extreme＇ host condition.

Flagstaff Urban Trails System and Its Inspiration for the Construction of China National Trails System

Flagstaff Urban Trails System(FUTS) is a city-wide network of non-motorized, shared-use pathways that are used by bicyclists, walkers, hikers, runners, and other users for both recreation and transportation. FUTS totals 79.2 km in Flagstaff, the Flagstaff government approved the fi rst plan in 1988, and FUTS Trail Priority Evaluation 2011 outlined the evaluation criteria, trail rankings and ranking results The new FUTS Master Plan shows about 130-km planned trails, and creates an ultimate trail system about 210 km. FUTS management organization and Transportation Tax Program is the key to keep the successful works of FUTS. Status quo of China National Trails System(CNTS) is reviewed as: scenic areas have relatively sound trail systems, but there is no any standard system; green corridors within the urban and rural system become popular, but there is no connection system. The development of China National Trails System can be promoted in 3 aspects: establishing national trails system, planning and design trails comprehensively, stressing daily operation and management.
