基于UAV低空遥感的荒漠林大沙鼠洞群覆盖率及分布特征研究——以新疆古尔班通古特沙漠南缘局部为例
摘要
Abstract
Grassland rodents are an important community component affecting the ecological balance of grasslands.Grassland rodent monitoring is also an important part of pest control.Unmanned aerial vehicle (UAV) low-altitude remote sensing is a new pest monitoring method,which has high spatial resolution,high efficiency,low cost,and low potential for loss.A demonstration project was conducted in Xinjiang to assess its potential as a rodent monitoring and control method.This project was conducted in October 2015 and May 2016 in a desert forest,which is the typical habitat of Rhombomys opimus in Xinjiang,near the southern edge of the Gurbantunggut Desert.A UAV low-altitude aerial survey was conducted in October 2015 and May 2016,0.02m and 0.024m,respectively,to obtain ultra-high resolution images of the experimental area.The experimental area was divided into two sections for visual interpretation to determine the distribution and conduct a buffer analysis of gerbil holes,and to add a trend line to the gerbil-hole distribution map based on spatial distribution trend analysis and the relationship between the holes and topography in the mountain shadow map overlay.Using GIS grid and GIS overlay analysis,a coverage map of all gerbil holes was created.Based on the results,it was concluded that:UAV lowaltitude remote sensing can provide highly accurate distribution information for Rhombomys opimus;the group coverage rate for Rhombomys opimus holes in the southern Gurbantunggut Desert forest zone was 19.4％,where 18.8％ has been considered a high density;the research area for Rhombomys opimus exhibited accumulation and zonal distribution characteristics;characteristics of the distribution of Rhombomys opimus holes leading to burrows was obtained for the study area;the zonal distribution of Rhombomys opimus holes and topography were closely related;spatial distribution characteristics could be used for scientific planning of rodent control;and UAV low-altitude remote sensing has broad applications for rodent monitoring and control.关键词
