Species-diversified plant cover enhances orchard ecosystem resistance to climatic stress and soil erosion in subtropical hillside

Naturally occurring plants in agroecosystem evidently play an important role in ecosystem stability. Field studies on the ecological effects of native plants conserved in orchard and their resistance to adverse climatic stress, and soil erosion were conducted from 1998 to 2001 in a newly developed Changshan-huyou (Citrus changshan-huyou Y.B. Chang) orchard. The experimental area covered 150 ha in typical red soil hilly region in southeastern China. The experimental design was a randomized complete block with six combinations of twelve plant species with four replications. All species used were native in the orchard. Plots were 15×8m^2 and separated by 2m buffer strips. Precipitation, soil erosion in rainstorm days and aboveground biomass of plant community when rainstorm days ended, soil temperature and moisture under various plant covers during seasonal megathermal drought period, antiscourability of soil with different root density under various simulated rainfalls were measured. Plant cover significantly decreased the daily highest and mean soil temperature and its daily variation in hot-drought season, but there was no significant difference of the alleviation among various plant covers. Plant covers significantly increased the soil moisture in seasonal megathermal drought period. Better moisture maintenance and soil erosion reduction was found when the plant species numbers in cover plant communities increased from one to eight. Higher root density in plant communities with higher species richness increased significantly the antiscourability of the soil. It was suggested that conserving plant communities with diversified native species could produce the best positive ecological effects on citrus orchard ecosystem stability.

Eco-compensation of Wetlands in Yellow River Delta of Shandong Province,China

Wetlands play an important ecological role and provide many functions for people, yet wetlands are cur- rently decreasing and deteriorating. The ability to calculate an economic value for the loss of wetlands is becoming in- creasingly important for policy makers. In this study, remote sensing, field investigations, department visits, and other methods were used to survey wetland types, assess wetland area changes, and calculate wetland economic value. Mar- ket value loss and ecological ftmction value loss, caused by reduction of wetland area and environmental pollution were calculated using commonly accepted methods of market valuation, ecological valuation, environmental protection investment cost analysis, and outcome parameters. According to market value loss and ecological function value loss, preliminarily fund allocation for wetland and ecological compensation was calculated. This will provide an important reference for future Yellow River Delta eco-compensation studies.

Forest eco-compensation mechanism:a survey

China is a country with a vast territory and a large population but limited forest resources, which is mainly distributed in the economically less developed regions. Therefore, it is particularly important to address the issue to establish forest eco-compensation mechanism to overcome the problems of inequity between the people and promote the public incentive for forest management and conservation. The definition of eco-compensation is deeply discussed based on the literature review of national and international initiatives. According to summary and analysis of the empirical work of forest eco-compensation at international level,some significant inspirations are duaw on this paper. Based on them, this paper focuses on the forest eco-compensation mechanism of china. Firstly, integrating with the actual situation of china, the paper puts forward the policy framework of eco-compensation .The institutional framework of eco-compensation should be established among the multi-departments with different temporal and spatial scales. Secondly, the types and ranges of forest eco-compensation are further studied, that is three levels of forest eco-compensation such as micro-level, macro-level as well as media-level, and then the standards of eco-com-pensation are primarily estimated which include the three factors, namely direct expense of plantation opporiunity cost for forests protection and benefits of forest ecosystem services.Finally the recommendation is created in terms of above research conclusions, which is provide the vital important references for government policy making in the forest eco-compensation domain.

Eco-compensation and Harmonious Regional Development in China

Research on the Application of Diversified Teaching in Gynecological Clinical Teaching

At present,the main body of clinical teaching in obstetrics and gynecology is still the traditional clinical teaching method,in which clinical teachers are the main body,and interns are the passive.It is not conducive to giving full play to interns'learning enthusiasm and ability to actively solve problems if lack of stimulating the clinical thinking and cultivating the ability to raise questions.In the face of the problems and deficiencies in gynecological clinical teaching in the new era,our team tries to adopt diversified teaching methods,such as medical record teaching method,multimedia teaching method,main-role teaching method,problem-based learning teaching method and so on,so as to improve students'ability of autonomous learning and problem-solving,as well as students'ability of innovation and cooperation.Therefore,clinical teaching teachers and teaching managers should keep pace with the times to carry out diversified teaching mode reform in gynecological clinical teaching.

Ecological and socioeconomic effects of China's policy for grassland eco-compensation

To reverse the continuous deterioration of grassland ecology and to improve the well-being of herders, China has been formulating many national policies on payments for grassland ecological conservation. One of them, the Grassland Eco-compensation Policy(GEP), is the biggest program for grassland protection in China since 1949. The GEP conserves natural grassland by paying herders cash subsidies. It also has worldwide significance because it can increase vegetative cover, improve the ecological balance, increase carbon sequestration and lessen the amount of dust reaching other countries through inhibiting soil erosion. Overall, we find that its ecological and socioeconomic effects are beneficial and further benefits may be observed in the future because while the socioeconomic effects usually appear quickly, ecological effects may take longer to manifest. 2015 is the last year for the first round of the GEP policy implementation and the extended policy for the GEP will be approved and continued by the central government. To make the policy more successful, we suggest coordinated planning, a comprehensive overview, higher compensation and collaborative study. Efficient implementation of the GEP could also provide valuable experience for other eco-compensation programs in China and numerous other regions of the world.
