摘要: 基于1938—2007年黄土丘陵区纸坊沟流域的调查资料,利用生态系统服务价值评估方法和生态足迹理论对该流域生态系统服务价值与生态足迹进行了测算,并分析了研究区农业生态系统与经济系统的互动关系.结果表明:1938—2007年,纸坊沟流域经历了3个阶段,即生态环境破坏-经济发展落后阶段(1938—1975年)、生态环境恢复-经济迅速发展阶段(1975—2000年)和生态环境保持良好-经济稳定增长阶段(2000—2007年);该区生态经济系统的互动关系表现为“生态恶化-生态、经济相互调节、适应-生态、经济良性互动”的过程.

Abstract: Based on the investigation data in 1938〖KG-*2〗-〖KG-*7〗2007 and by using the evaluat ion method of ecosystem service value and the ecological footprint theory, the e cosystem service value and ecological footprint in Zhifanggou watershed of Loess Hilly Region were calculated, with the interactive relations between agroecosys tem and economic system in the watershed analyzed. From 1938 to 2007, Zhifanggou watershed experienced three development stages, i.e., ecological environment de struction with backwardness of economy (1938〖KG-*2〗-〖KG-*7〗1975), eco-envir onment restoration with rapid development of economy (1975〖KG-*2〗-〖KG-*7〗200 0), and well-maintained ecological environment with stable growth of economy (2 000〖KG-*2〗-〖KG-*7〗2007). The interactive relations of the eco-economic syst ems manifested as ecological deterioration, eco-economic adaptive regulation, a nd eco-economic benign interaction.
