摘要
以湖州市为研究区域,landsat5、landsat8为数据源,利用归一化植被指数,选定合适的阈值,把研究区域分为植被、水、非植被三类,并测算湖州市植被覆盖面积。经过比较湖州市各区各年份植被覆盖变化情况,结合湖州市历年政策政令,分析湖州市2005-2018年植被覆盖变化原因,为湖州市制定政令等提供参考。
Taking Huzhou City as the research area,and Landsat 5 and Landsat 8 as data sources,the research area is divided into three categories:vegetation,water and non-vegetation,and the vegetation coverage area of Huzhou City using the normalized difference vegetation index,selecting appropriate thresholds.By comparing the changes of vegetation cover in Huzhou City in different years,and combining with the policies and decrees of Huzhou City over the years,the causes to the changes in Huzhou City from 2005 to 2018 were analyzed,providing a sort of references for Huzhou City to formulate the decrees.
