摘要
对三江源区称多县高寒草甸的鼠虫害进行了调查研究,应用ArcGIS软件,采用反距离加权插值(IDW)方法,将鼠害、虫害危害分级标准分为5级,制成了称多县高寒草甸的鼠害分布图和虫害分布图。结果表明,在称多县鼠害危害面积大,主要发生在清水河镇和珍秦镇,而草原毛虫危害主要发生在珍秦镇。根据鼠虫害的分布图,提出了称多县今后鼠虫害防治工作的重点区域及防治对策。
The rats and pests in alpine grassland of Chengduo County in the source region of three rivers were investigated, the damages caused by rats and pests were graded into five levels with the ArcGIS software and by the inverse distance weighted interpolation （IDW） meth- od. The distribution maps of rats and pests were drawn. As indicated by the results, the damage area of rats was large in Chengduo County, especially in Qingshuihe Town and Zhenqin Town, the damage of Gynaephora alpherakii was mainly found in Zhenqin Town. According to the distribution map of rats and pests, the major areas of rats and pests and the control measures were proposed.
