榆林地区景观生态敏感性时空特征
Spatial-temporal characteristics of landscape ecological sensitivity in Yulin area
摘要
Abstract
The analysis of landscape ecological sensitivity is one of the important research objects of ecological environment.In order to analyze the spatial-temporal characteristics of landscape ecological sensitivity, the authors divided Yulin area into 527 units by 10 km×10 km grids.The index of landscape ecological sensitivity for each unit was calculated by weighted sum method, and then interpolated by Kriging in ArcGIS to get the landscape ecological sensitivity map.According to sensitivity index, landscape ecological sensitivity was classified into 5 levels: Insensitive, mild, moderate, high and extreme.From 2000 to 2005, the area of mild level and extreme level increased, and that of moderate level and high level decreased, with the weakening of landscape ecological sensitivity.From 2005 to 2010, the area of mild level decreased greatly, the area of moderate level and high level increased slightly, the area of high level increased greatly, and the area of extreme level also increased, with the increase of the landscape ecological sensitivity.关键词
