中文摘要：

以区域土地利用／覆被数据为基础，分析了天山北坡生态系统服务价值的时空变化特征，并通过构建生态经济协调度（EEH）指数评价了区域生态经济发展水平及区域差异性．结果表明：天山北坡生态系统服务价值从1989年的319．93亿元增加到2000年的321．26亿元，增幅0．42％；区域整体生态经济发展处于低协调水平，东部地区协调度高于中、西部，其中8个市县的EEH值为正，生态经济发展处于协调水平，7个市县的EEH值为负，处于不协调水平．研究区生态经济发展已处于协调水平的边缘，须加强生态环境保护力度，促进生态经济协调发展，以最终实现区域的可持续发展．

英文摘要：

Based on the data of land use/cover and by using eco-economic harmony index （ EEH）, this paper studied the spatiotemporal characteristics of ecosystem service value on the northern slope of Tianshan Mountains, and evaluated the harmony degree of eco-economic development in the region. The results showed that the total ecosystem service value on the northern slope of Tianshan Mountains was increased from 319.93 × 10^8 yuan in 1989 to 321.26 × 10^8 yuan in 2000, with a net increment of 0. 42%. The regional eco-economic development was overall at a low harmony level, being higher in eastern part than in middle and western parts, among which, eight counties had a positive value of EEH and their eco-economic development was harmonious, while seven counties had a negative value of EEH and their eco-economic development was inharmonic. The eco-economic development in the region was at the margin of harmony, and thus, more attention should be paid to strengthen the protection of eco-environment and promote the harmonious development of eco-economy to have a sustainable development.
