摘要: 基于1990年、2000年和2010年的同期TM遥感影像数据,借助RS与GIS技术,针对新疆焉耆盆地内各土地类型变化、系统稳定性和生态服务价值等问题进行系统分析。结果表明:① 1990—2010年,焉耆盆地土地利用覆被发生了较大变化,以耕地面积明显增加,草地面积有所减少为主要特点,耕地的迅速扩张主要发生在2000—2010年;② 2000—2010年的土地利用信息熵和均衡度迅速增加,表明这一时期土地利用系统的无序化进程剧烈,且加速上升,系统不稳定性增强,威胁到流域绿洲的稳定性,进而危及塔里木河下游生态安全;③ 焉耆盆地土地整改过程中,生态服务价值先上升后下降,水资源的大量消耗,并未实现区域“生态-经济-水”的协调发展,反而导致绿洲生态服务功能下降,生态服务价值未升反降的绿洲开发模式值得深思。

Abstract: In this paper, the land use/cover change (LUCC), system stability and ecosystem service value in the Yanqi Basin, Xinjiang, China were investigated based on the land use/cover classification data derived from the Landsat TM images in 1990, 2000 and 2010. The results are as follows: ① During the period of 1990-2010, the land use/cover change in the Yanqi Basin was obvious, which was characterized by the enlargement of cultivated land area and the reduction of grassland area to some extent, and the rapid expansion of cultivated land occurred during the period of 2000-2010; ② During the period of 2000-2010, the information entropy and balance degree of land use were rapidly increased, which revealed that the instability of land use system and the instability of oasis were serious, and then the ecological security in the lower reaches of the Tarim River was threatened; ③ The value of ecosystem services in the study area was increased at first and then decreased, and the harmonious development of the “ecology-economy-water” did not be achieved due to the big consumption of water resources, which should be emphasized.
