Eco-Safety Assessment of Agricultural Sustainable Development in Jiangxi Province

Based on the status quo of the agricultural sustainable development in Jiangxi,an ecological safety assessment index system was set up.Using the clustering method,eco-safety of the agricultural production in Jiangxi Province was divided into four grades,i.e.unsafe,relatively unsafe,relatively safe and safe.According to geographical variability,the ecosystem of the circum-Poyang Lake region has suffered a certain degree of damage.The South Jiangxi region was quite poor in agricultural eco-safety,and the ecological problem with its agriculture is outstanding.In the Central Jiangxi region,the agricultural ecosystem is basically intact in structure and the agricultural eco-safety is quite good.Out of the 11 district-leveled cities in Jiangxi Province,six,including Ji′an fall into the relatively safe grade and the other five,including Yingtan,in the relatively unsafe grade.In light of the status quo of the agricultural sustainable development in Jiangxi,problems in construction of agricultural eco-safety systems are discussed,which will be of certain value to optimization of disposition of the regional agricultural resources and guidance of agricultural development.
