利用时序NDVI分析安徽省植被参数时空变化
Spatio-temporal Change Analysis of Vegetation in Anhui Province Based on NDVI Time Series Data
摘要
Abstract
Based on the NDVI time series data of Anhui Province from 2000 to 2020,using the trend analysis method and combining with the time series change characteristics of Anhui Province,we studied the spatio-temporal evolvement rules of NDVI in Anhui Province.The results show that ①NDVI of Anhui Province shows a slow growth and the vegetation coverage shows a significant increase from 2000 to 2020.②NDVIs of six soil and water conservation zones in Anhui Province show two single peak,indicating that the vegetation coverage in Anhui Province is mainly affected by agricultural farming activities.③NDVI of Anhui Province appears small fluctuation rise in spring,summer,autumn and winter,and the increasing tendencies in spring and summer are obvious than that in autumn and winter.The vegetation coverage of Anhui Province in 20 years has increased,and this phenomenon may be related to a series of activities such as artificial vegetation restoration and ecological protection.关键词
