基于EVI的中国最近10a植被覆盖变化特征分析
Variation characteristics of vegetation cover in the latest 10 years over China based on EVI
摘要
Abstract
Analysis on the variation data of Enhanced Vegetation Index (EVI) from 2000 to 2009 found that the vegetation coverage was obviously increasing and the vegetation activity was enhancing in China during the past ten years.The characteristics of interannual and interseasonal vegetation coverage variation were as follows:(1) the area of vegetation coverage was increasing while the area of bare land was decreasing;(2) the mean EVI per unit land either in vegetation coverage areas or in the average areas of the whole country was increasing in the past ten years;(3) vegetation activity enhanced obviously in growing seasons (summer,spring),and the growth rate of EVI was ordered according to season as summer＞spring＞autumn＞winter.The spatial variation features of vegetation coverage show that although the vegetation coverage presents increasing trend in China,the spatial difference exists.The increasing of EVI around China could be caused because of:(1) the increasing temperature and precipitation in spring;(2) large forestry ecological construction projects.关键词
