SPOT-VGT时序数据的土地覆盖应用
Application of SPOT-VGT Time Series Data in Land Coverage
摘要
Abstract
Supported by the data source of ten days maximum value composite SPOT VGT/NDVI time series of 1999, according to principal components analysis and unsupervised classification, study area was classified in the area of land cover use. The NDVI change curve of the,typical ground feature was extracted. The phenology change in a year was analyzed. The inter-annual variation was analyzed from the degrees of change and the type of change code. The results showed that the ecology of the western region in Jilin Province degraded seriously. SPOTVGT time series had a very good potential use advantage in the study of land coverage.关键词
