| 摘 要： | 新疆塔里木河流域以胡杨为建群种的荒漠河岸林是我国及世界上胡杨分布最为集中的地区之一。通过分析该地区土壤含水率、地下水埋深、地形地貌类型与胡杨空间分布、龄级结构、郁闭度的关系，探讨其生长状况。同时，采用１９８３年、１９９２年及１９９６年遥感信息源编制植被专题图件，在ＧＩＳ支持下处理图件，并应用制图数据及相关自然及人文数据，分析胡杨面积变化及演替规律，强调了系统重建设及恢复的重要作用。

| Abstract: | Desert riparian forest dominated by Populus euphratica in Tarim River Basin is one of its centralized distribution areas at home and abroad.The growth status of Populus euphratica is discussed depending on analyzing relationship among soil moisture,groundwater depth,terrain feature and regional distribution,age class structure,coverage.Meanwhile,based on remote sensing sources of 1983,1992 and 1996,the thematic maps of vegetation are made.With the support of GIS,the maps are processed.Moreover,the area changes and evolution patterns are analyzed according to mapping data and natural as well as artificial data.As a result,the importance of system rebuilding and restoration is strengthened. |
