摘要
利用"北京一号"小卫星数据,以密云水库流域为研究区域,采用归一化植被指数(NDVI)像元二分法,进行地面植被覆盖度估算研究,并对估算结果进行实地检验和分析,其估算值与实际值之间的相关性较高(86%)。结果表明,利用"北京一号"小卫星数据进行植被覆盖度估算及监测应用是可行的。
This article explores the feasibility of using ＂Beijing-1＂ microsatellite data to estimate vegetation fraction based on the study area of the Drainage basin of Miyun Reservoir by using binary pixel method. Through validating with field collected data, the average accuracy of estimated vegetation fraction of all land cover types is more than 86% in the study region. The results show that it is feasible to estimate and monitor the vegetation fraction by using ＂Beijing-1＂ microsatellite data.
