摘　　要：文中基于改进的CASA模型计算神东矿区植被净初级生产力,探究矿区十年来不同开采强度区域NPP时空分布情况和变化特征。结果表明研究区三期NPP逐年递增;矿区植被NPP时空分布与土壤环境,高程以及植被梯度较一致。除低开采区以外,其他采区和非采区增长率均大于20%,不同开采强度下的工业活动无明显规律性变化。煤炭开采活动未对神东矿区的植被造成破坏。研究成果可以很好地反映区域生态环境质量,为生态环境建设规划提供重要依据。Based on the improved CASA model, in this paper, the net primary productivity of vegetation was calculated in Shendong mining area, and the spatial and temporal distribution and variation characteristics of NPP was explored in different mining intensity areas in the mining area in the past ten years. The results showed that the NPP in the third phase of the study area was increasing year by year;the spatial and temporal distribution of NPP in the mining area was consistent with the soil environment, elevation and vegetation gradient. Except for low-mining areas, the growth rates of other mining areas and non-mining areas were all greater than 20%, and there was no obvious regular change in industrial activities under the different mining intensities. Coal mining activities did not cause damage to the vegetation in Shendong mining area. The research results could reflect the quality of regional ecological environment and provided an important basis for ecological environment construction planning.
