Abstract:

Protection and development of traditional agriculture have an important meaning for increasing regional resource sustainable utilization value.Taking Jinniu Village,a traditional agricultural area of the Southern Yangtze River as an example,the ecological services value of paddy system was evaluated with market value approach,production cost approach,opportunity cost approach,shallow project approach and cost surrogate approach.The ecological value coefficients of cropland, garden plot,woodland and water body ecosystems were adjusted by combing with biomass and price index based on the study of Chinese ecosystem services value.Then the changes of ecosystem services values of Jinniu Village were predicted and analyzed before and after the implement of land use planning.The results showed that during 2008 and 2020,the increase of ecological service functions would range from 10.70% to 100.73%,the total ecosystem services value would increase from 65680×104 yuan to 1 02210×104 yuan,and the proportion of paddy system in the total value would range from 50.67% to 53.63%.Sensitivity analysis manifested that the ecosystem services values of Jinniu Village were generally inelastic,and the ecological value coefficients calculated by this paper were reasonable.The land use planning would basically bring Jinniu Village a considerable ecoenvironmental benefit,while the water body should be increased in order to promote tourism attraction.〖
