【摘要】 生态系统服务价值的变化决定着区域的可持续发展,其评估已成为生态学研究的热点之一。本文采用单位面积生态系统服务价值和生态经济协调度(EEH)指数,分析了南京市生态系统服务价值时间变化及区域差异。结果表明:2007年与1997年比较,所处单位面积生态系统服务价值分区不同的区域有建邺区等6个区,2个时段均处于同一单位面积生态系统服务价值分区的区域有高淳县等7个区、县;区域整体单位面积生态系统服务价值大体上呈现郊县>郊区>城区的特点;1997—2007年南京市11区2县属于5种不同类型的生态经济协调度分区,其中建邺区等5个区、县处于生态经济协调区,秦淮区等8个区处于生态经济不协调区。最后,探讨了南京市不同区域生态建设调整措施,为促进生态经济协调发展和实现区域的可持续发展提供决策参考。更多还原

【Abstract】 The changes of ecosystem service value affect the sustainable regional development,and the valuation of ecosystem service has been one of the hot topics in ecological study.By using per unit area ecosystem service value and eco-economic harmony index(EEH),this paper analyzed the temporal variation and regional differences of ecosystem service value of Nanjing.With the comparison in 2007 and in 1997,Nanjing City had six districts with the sub-zones of different per unit area ecosystem service value,while seven districts and counties having the same per unit area ecosystem service value sub-zones.In general,the regional per unit area ecosystem service value showed the features of counties > suburban areas > urban areas.In 1997-2007,the eleven districts and two counties of Nanjing City were of five different types of eco-economic harmony zones.Three districts and two counties belonged to eco-economic harmonious zones,while the other eight districts belonged to eco-economic inharmonious zones.The strategies of ecological construction adjustment in different districts and counties of Nanjing City were put forward,which could provide reference for the decision-making of the harmonious eco-economic development and regional sustainable development of the City.更多还原
