【摘要】 本研究以塔里木河上游农一师10个团场为研究靶区,在前人研究成果的基础上,探索该区生态系统服务功能的价值,并分析其变化特点及其主要驱动因素,研究结果表明:该区经济是以绿洲农业为主,农田和未利用土地居多,林草和水域面积均不及13%。1991年到2005年,该区农田面积大大增加,未利用面积大大减少,但是森林、草地和水域面积均有所减少。在这15年期间,该区各类型生态系统服务功能的贡献大小顺序没变,仍然是水域>农田>林地>草地>未利用土地,但是生态系统服务功能价值的变化重点体现在内部价值转移上,森林、草地以及水域等自然生态系统的部分服务功能被人工农田生态系统所替代。该区人类活动所导致各类型生态系统面积及其服务功能单价变化是生态系统服务功能价值变化的主导因子,其中科学技术以及农业生产是其中的主要因子。塔里木河流域的生态系统服务功能价值变化与人类社会经济活动有直接关系。更多还原

【Abstract】 We choose the upriver reaches of Tarim River as our estimating object,based on the research production,and value the ecosystem services,and analyze its change characteristic and the major control factors.The results showed as follow,the oasis agriculture is superior in the economy of this region,and farmland and undeveloped land are in the majority.The area of farmland increase greatly and the undeveloped land decrease enormously from 1991 to 2005,at the same time,the areas of forest and grassland and water part reduce.The sequence of value of ecosystem services has been still the same,which is that the water area’s is the biggest and the undeveloped land’s is the smallest.The value transformation in the inner is the outstanding trait of the value change of the ecosystem services.The part value of ecosystem services from forest and grassland and water area is substituted by the value of farmland.The main factors that influenced on the value change of ecosystem services are the change of ecosystem area and the price of ecological services affected by anthropogenic activities,and the technology and the agriculture yield are the major control factors.The value change of ecosystem services in the Tarim River is directly correlative with the anthropogenic activities.更多还原
