摘要
通过遥感、地理信息系统及现场调查的方法,对塔里木河上游段沙雅县1989年和2009年2期卫星影像进行遥感解译,从面积、空间格局、林分质量等角度,分析了沙雅县胡杨林20年的演变情况,查找了演变的原因,并据此提出了胡杨林的保护措施。
By using the remote sensing,geographic information system and field survey,two satellite images of Shaya County in the upstream of Tarim River in 1989 and 2009 were interpreted,respectively.Based on the area,space pattern and forest quality,etc.,the historical data of Populus euphratica in Shaya Country during the past 20 years was analyzed,and the causes to this change were found.And finally some protective measures on Populus euphratica were put forward.
