基于多时相Landsat遥感影像的海州露天煤矿排土场植被时空特征分析
Monitoring of temporal and spatial change of vegetation in waste dump of Haizhou opencast coal mine area using multi-temporal Landsat remote sensing images
摘要
Abstract
Land reclamation in coalmine area is an important task of land consolidation, which ensures sustainable development of coalmine area. Vegetation and its recovery state is an important indicator of land reclamation quality, indicating the state and quality of land reclamation in coalmine area. Based on 4 phases′ remote sensing images from 1975 to 2000, vegetation fraction index is used to indicate vegetation growth status and temporal/spatial variation result of waste dumps of Haizhou opencast coal mine area in 25 years. Experiment results indicate that vegetation in study area is in the process of developing and gradual recovery status, the area proportion of high vegetation fraction (0.4-0.6) zone increase from 14.04% in 1975 to 34.83% in 2000; the distribution of this high vegetation fraction area is temporal and spatial variated, low vegetation fraction area (0-0.2) is in the slope of different terraces and high vegetation fraction (0.4-0.6) area is in the middle of which.关键词
