基于作物生态足迹的江苏省市域种植业可持续发展研究

以江苏省各地市种植业的可持续发展情况为研究对象,采用作物生态足迹模型和作物生态可持续指数计算并分析2014年江苏省13个地市的种植业可持续发展情况及区域差异。结果表明:总体上看,江苏省种植业处于生态盈余状态,各地市种植业都处于可持续发展状态。具体表现为:作物生态足迹、生态承载力和生态盈余均表现为由苏北向苏中、苏南递减的趋势;各地市的作物生态可持续指数都大于0.5,其区域差异为苏南地区好于苏中和苏北地区,苏南的无锡、常州、苏州、镇江和苏北的宿迁的种植业处于强可持续性状态,其余地市处于弱可持续性状态。

Study on Sustainable Development of Planting Industry in Cities of Jiangsu Province Based on Crops Ecological Footprint

With sustainable development situation of planting industry in each city in Jiangsu Province as study object, using crops ecological footprint model and ecological sustainable index, the sustainable development situation and regional difference of planting industry in 13 cities in Jiangsu Province in 2014 were calculated and analyzed. The results showed that in general, planting industry in Jiangsu Province was in ec-ological surplus and sustainability state. For specific performance:crops ecological footprint, ecological carrying capacity and ecological sur-plus presented decreasing trend from northern Jiangsu Province to southern Jiangsu Province; crops ecological sustainable index in each city were all above 0. 5, regional difference in southern Jiangsu Province was better than that in central and northern Jiangsu Province, planting in-dustry in Wuxi, Changzhou, Suzhou, Zhenjiang of southern Jiangsu and Suqian of northern Jiangsu were in strong sustainable state, other cit-ies were in weak sustainable state.
