The Theoretical And Empirical Study Of Ecological Value Assessment Of Traditional Agro-ecosystems

With the development of agricultural heritage excavation, conservation work, traditional agricultural ecosystems as a living agricultural heritage potential areas has highly concerned by scholars, this paper has been built on the basis of the conceptual framework of the agricultural heritage to discusses the theoretical methods to assess the ecological value of traditional agro-ecosystems, and then for Yun county Daliu Villages as a kind of empirical research to provide a theoretical basis to Agricultural heritage during the investigation to assess the value of traditional agricultural ecosystems ecology,and then lay the foundation to choice,development and protection the pilot area of agricultural heritageWith the help of the Concept discriminate and Analogy method, According to the characteristics of the agricultural heritage and define the general agricultural ecosystems, has a definition on traditional agriculture ecological system, then analyzed the characteristics of their ecological value, On this basis, using the Delphi method from the four aspects of biodiversity, ecological carrying capacity, ecosystem services and ecosystem stability index system for the establishment of a valuation of the traditional agricultural ecosystems ecology, selected21indicators factor, While using a chromatographic analysis to determine the weight of each factor to provide a reference for the quantitative study of agricultural heritage; Finally, Explore the meaning of the characteristics of each indicator, and the use of landscape diversity index, overlay analysis, mathematical analysis of the market value of the data to obtain quantitative indicators s, such as the assignment of methods to quantify the qualitative indicators,and use level assignment methods to qualitative indicators.We have select"Corn-soybean/dwarf cucumber" intercropping system,"Dwarf soybeans -sweet potato" intercropping system and "Wheat and corn even do add organic green manure "farming systems in north west Hubei Province in Daliu villages, using arcgis software for acquisiting the spatial data, The results are displayed on Biological Diversity three ecosystem are in general lower level, On the ecological carrying capacity " Wheat and corn even do add organic green manure "forming systems is better than the other two ecosystems and display a high conversion levels, On ecosystem services,"Corn-soybean/dwarf cucumber" intercropping system is generally to higher conversion levels, the other two are general level;, On stability in the ecosystem,"Wheat and corn even do add organic green manure "farming systems is more stable, The total ecological value, all of them are in general,"Corn-soybean/dwarf cucumber" intercropping system is the largest in the region, This is consistent with the results of the field research, Accordingly results to discuss the traditional ecological agriculture system formation conditions of the ecological value, Inspiration and combing analysis and evaluation of agricultural heritage survey.
