摘　　要：本研究区位于塔里木河中游地区,本研究选取耕地变化、输水堤防的建设以及油气田开发三种土地利用方式,在大量野外调查的基础上,在3S技术和历史数据的支持下,分析了这些土地利用方式变化对胡杨林生态系统的影响。研究结果表明:研究区1992年之后内耕地大量增加,输水堤防对堤防内外侧胡杨生态系统具有不同影响,油气田开发会造成生态破坏和环境污染等问题。Research area located in the middle reaches of Tarim River, and land use types in this area include cultivated land, oil -gas field, and water transfer dike etc. Our research focus on changes in these three land use types and its influences on Populus euphratica forest. With the support of 3S, by field survey, the impacts of these factors on changes of Populus euphratica forest were analyzed. The results shows there have been opened cultivated land largely; Water transfer dike construction has different effects on the inside and outside ecosystem of the dike ; Oil - gas field exploitation also occupied some places permanently ; Furthermore, it influences plant growth around the field.
