摘　　要：研究采矿扰动区长时序、多维度NDVI变化趋势,有助于认识非自然生态区植被演替规律,对高强度开采条件下西北脆弱生态区地表植被自然修复和人工修复工作具有指导意义.研究通过设立直接影响区、间接影响区和自然生态校验区,利用长时序GIMMSAVHRR/NDVI(1981~2006)植被指数数据集,结合同期温度、降水和煤炭产量信息,从时间、空间、气候和开采强度方面开展对比分析,并以长时序MODISNPP/NDVI(2000~2010)数据进行结果验证.时序分析表明,全球变化背景下,神东矿区植被生长季二度延长;空间分析表明,神东矿区NDVI增量低于缓冲区,缓冲区NDVI增量低于自然生态区;开采强度分析表明,随着神东矿区开采强度增强,NDVI增速放缓,增长速率低于自然生态区;气候变化分析表明,神东矿区NDVI受温度升高、降水减少共同作用,与温度相关性较高,与降水相关性较低;同期MODISNPP/NDVI验证结果表现出与AVHRR/NDVI一致的规律性.Study purpose on biological productivity inverted from a long time series, the multi-dimensional NormalizedDifference Vegetation Index (NDVI) in mining-disturbed areas is to understand vegetation succession of non-naturalecological areas, while to provide guidance for natural restoration and artificial restoration of the vegetation underhigh-intensity mining conditions northwest fragile ecological areas in China. Shendong coalfield, as a directly affectedarea, an indirectly affected area (20 km buffer), and a natural ecological checked area were established. Using GlobalInventory Modeling and Mapping Studies Advanced Very High Resolution Radiometer derived NDVI dataset (GIMMSAVHRR/NDVI) (July 1981-December 2006, 25.5 years), combined with temperature and precipitation information (86meteorological stations) and Shendong coal output, the aforementioned three areas are comparatively investigated for theeffects of temporal, spatial, climatic, and mining intensities. Test validation is conducted by means of another long-termModerate Resolution Imaging Spectroradiometer (MODIS: MOD17A3 and MOD13Q1) net primary productivity(NPP)/NDVI (2000~2010, 11 years) dataset. The results will provide new insights into ecological environment inmining:(1) under the background of climate change, the vegetation growing season was extended again in the Shendongmining area;(2) NDVI increment in the Shendong mining area was below the buffer, and NDVI increment in its bufferwas lower than the natural ecological area;(3) In the mining area, with the increase in mining intensity, NDVI growth ratewas lower than that of in the natural ecological area.
