Agroecosystem health assessment on the saline-alkali district in Luyang Lake
摘要
Abstract
This research established an index system of agroecosystem health assessment by analyzing vigor ,organic structure and resilience of the agroecosystem . The index weight was calculated through the analytic hierarchy process (AHP) .Finally ,comprehensive index method was used to calculate the ecosystem health index and analyze the health level by the evaluation standard .The results showed that in 2012 ,the agroecosystem health comprehensive evaluation value of Luyang lake saline-alkali district was 5 .772 ,which was between grade II and III (means partial sub-healthy state ) .There were some problems for each index at different scales .The main factors that restricted the development of agriculture in Luyang lake district included large density and the low overall quality of the population ,the lack of land resource ,serious soil erosion ,over exploitation of natural resources ,single agricultural industry and backward production mode .关键词
