Traditional eco-agriculture provides many ecosystem services which are important for the local environment, especially in mountain areas. In order to encourage the farmers to engage in coo-agriculture, it is necessary to establish an eco-compensation mechanism for them. As the compensation standard is one of key issues in establishing eeo-compensation mechanism, this paper calculated the standard based on the farmers' willingness to accept (WTA) and the input-output analysis of eco-compensation. We took the traditional rice-fish eco-agriculture as the research object, conducting field surveys in Hani Terrace of Honghe County. Through the questionnaires in 2o11, we obtained the farmers' willingness to accept government compensation and market compensation. Then, the research evaluated the output of eco-compensation, the economic value of rice-fish paddy ecosystem services. Finally, under different market compensation standards, we compared the input and output of government compensation. The results show that, in 2011 the government should to pay farmers 7462 yuan.ha^-1·a^-1 to meet their willingness, but the output (ecological benefit) was only 7393 yuan.ha^-1·a^-1. However, whenthe rice price increases 1 yuan·kg-1 because of the limited use of chemicals in the next year, the government just has to pay farmers 4062 yuan.ha^-1·a^-1 and the surplus will be 3331 yuan.ha^-1·a^-1. 展开更多

Valuating the fimction of ecosystem services is crucial for accounting green GDP, making a conservation policy of ecological environment and the decision of regional development as well as sustainable development strategy. R ice-duck-fish symbiosis has been promoted in several developing countries as a way of increasing incomes for rice farmers, but investigations of its value have mainly focused on direct economic' benefits, such as food and raw material production. Few studies have been conducted on the estimation of indirect services provided by rice-duck-fish complex ecosystem. The gas regulation service and its economic values provided by rice-duck-fish complex ecosystem were studied in Wuhan, China. The major components of gas regulation are O2 emission and greenhouse gases (GHGs, CO2) regulation. The results show that O2 emission from different treatments (including rice-duck (RD), rice-fish (RF), rice-duck-fish (RDF) and rice (CK)) ranged from 26,370 kg/ha to 33,910 kg/ha per year. with an economic value of 10,050-12,920 yuan/ha per ),ear (Chinese currency: 1 euro =10.2475 yuan, August 28, 2007). The net GHGs exchange varied from 1,200 to 3,320 kg/ha per year; and its economic value ranged from 1,040 yuan/ha to 2,900 yuan/ha per year Consequently, the total economic value of gas regulation provided by symbiosis complex ecosystems ranged from 11,090 yuan/ha to 15,820 yuan/ha per year. and the maximum overall economic value of gas regulation was provided by RDF complex ecosystem. The work will be useful for further understanding of the functions of rice-duck-fish complex ecos.vstem services and supplying the theoretical references to agricultural policy. 展开更多

Traditional rice-fish agricultural heritage site in Qingtian County, China, one of the pilot sites of Globally Important Agricultural Heritage Systems (GIAHS), is of great value in tourism development. This paper aims to explore how to realize sustainable tourism development in agricultural heritage site through identifying current problems in GIAHS site. and making constructive recommendations for coupled development of heritage preservation and economic development. Field survey was carried out and data was collected through field questionnaire surveys of tourists and residents in Longxian Village of Qingtian County, as well as interviews of residents with semi. structured questionnaires for their perceptions and attitudes to tourism development. The following results are got: (1) the tourism industry is still at its early state of Non, tale tourism (enjoy and experience authentic country life- style), under very limited administrative management; (2) what attracts visitors most are delicious.fish and beautiful natural environment, but not agricultural heritage itself; (3) most tourists eome from adjacent areas and stay. only half day, many of whom pay their visits twice or more; (4) a few local residents take part in the activities of tourism industry, but in very limited manners even if they do. Current patterns of tourism development are casting negative impacts on agricultural heritage. Conservatton of agricultural heritage should be put in the first place for sustainable tourism development.Agricultural heritage, as a key attraction, should be taken as the focus for tourism development. The important thing is to change the present Nongjiale tourism into real heritage tourism, to establish a cooperative mechanism among different stakeholders. and to increase local residents' income through engaging in tourism industry. 展开更多

In order to better understand the developmental conditions and trends of the biodiversity at agricultural heritage sites,the structure and function of the ecosystem and ecological environment in Qingtian Rice-Fish Culture System is examined in the decade since the implementation of the GIAHS project.Through the collection of historical data and sample-plot survey,this study collates the data from 2005 to 2013 related to the heritage site to evaluate the ecological benefit of the Agricultural Heritage System conservation.The results show that:(1)Since the implementation of heritage conservation,the variety of traditional rice grown at the heritage sites basically remains stable,the varieties of other crops basically remain unchanged and the varieties of fruit trees and medicinal plants have developed at faster rates.As the ecological environment at the heritage sites gradually improved,the species and richness of the biodiversity in the ecosystem have increased,especially the increasing growth of egrets and boars.(2)From 2005 to 2013 in the Fangshan Town of Qingtian County,the ecosystem areas identified as river,forest,urban and bare land have increased.The increased area of the urban ecosystem is the largest one of them,which is up to 20.30 ha;while the area of the forest ecosystem has increased to 7.29 ha.The areas of wetland,reservoir,farmland and grassland have been reduced,and the area of grassland ecosystem has been reduced the most with a reduction of 28.87 ha.From the changes in the values of the ecosystem services of different ecosystem types,the values of forest ecosystem services have achieved the most growth,reaching up to 92000 yuan yr-1 and the growth of the river and bare land ecosystem service values are not obvious.(3)Over nearly a decade,the soil nutrients and the water quality of rice fields at the heritage site have not obviously changed and the plant diseases and insect pests in the rice fields have not been aggravated.The monitoring indexes are far better than the standard values.With the great support of the local government,the production and living conditions and the living environments of farmers in the villages of the heritage sites have been greatly improved through road reconstruction,water improvement,toilet enhancements and the greening,brightness and beautification of the villages. 展开更多

Scientific and effective heritage monitoring can not only realize the conservation of the heritage itself and the maintenance of its values,but it can also realize the sustainable development of the heritage site.In order to promote the conservation and management of Globally Important Agricultural Heritage Systems(GIAHS),this study proposed a design for the annual report of GIAHS monitoring under the overall framework of the GIAHS monitoring system,and explored the application of the annual report in the first GIAHS site in China:the Qingtian Rice-Fish Culture System.In the design scheme of this study,the GIAHS annual monitoring report is composed of 24 monitoring items,with each of them logically related.It is to be filled in by the bureaus of the heritage site and reported through the GIAHS dynamic monitoring system.The results of an analysis of the annual reports of Qingtian Rice-Fish Culture System for four years showed that Qingtian County has taken a series of conservation and development measures which have reduced the area of abandoned paddy,enhanced the unit benefit of agri-products,and increased the farmers’income.At the same time,the heritage site is faced with various challenges and threats,such as the weakening of the tourism attraction,the aging of the heritage practitioners,and the limitation of the heritage-themed agri-products and tourism income,which need to be addressed with proper measures.The results can also provide guidance for other GIAHS based on indications that heritage sites should improve the development of cultural products,the construction of social organization and the cultivation of spontaneous publicity,and an exchange and learning mechanism should be established among them in the future.The design and application of the GIAHS annual monitoring reports can not only provide specific guidance for conducting the GIAHS monitoring,but also lay the foundation for evaluating the effectiveness of GIAHS conservation and management.This study is expected to help enrich the theory of GIAHS monitoring,further promote China’s GIAHS monitoring work,and also provide China’s experience for the benefit of international GIAHS monitoring efforts. 展开更多
