摘　　要：为探寻胡杨(Populus euphratica Oliv.)春尺蠖(Apochemia cineraius Erschoft)蔓延的驱动因子,以叶尔羌河流域中下游夏河林场作为研究区域,采用2001-2016年多时相、中等分辨率的MODIS NDVI数据提取虫害发生区域并划分等级,分析虫害蔓延规律,探寻影响胡杨春尺蠖蔓延的驱动因素.结果表明:2001年至今,春尺蠖虫害各等级发生面积均有增加,发生范围也在逐年蔓延,由无虫害转移至有虫害的面积占比达59%,发病率已超过50%,急需针对重灾区开展精准治理;在胡杨春尺蠖蔓延过程中,地表温度起主要作用,其次是灾害区距河流距离,灾害区距主要公路距离,影响最小的是到虫源点的距离.To explore the driving factors of Apochemia cineraius Erschoft of Populus euphratica spreading in Xiahe Forest Farm in middle and lower Yeerqiang River Basin in Xinjiang, the multi-temporal and mediumresolution MODIS NDVI data from 2001 to 2016 were used to extract the pest occurrence area, the spreading law of the pest was analyzed. The results showed that the area of all grades of Apochemia cineraius had increased, and the range of occurrence had also spread year by year since 2001. The area from pest-free to insect-affected accounted for 59% of the total, and the incidence rate had exceeded 50%, which means to manage the hardest hit areas precisely is urgent. In the process of Apochemia cineraius spreading, the surface temperature played a main role, followed by the distance to the river, the third factor was the distance to the main road, and the least affecting factor was the distance from the insect source.
