摘  要：
通过改进的CASA模型对神东矿区植被NPP(植被净初级生产力)进行估算,研究该矿区整体植被变化。分析了大柳塔、补连塔、榆家梁等3个矿井植被变化情况;并对矿区采区与非采区的植被生长状况进行对比研究;采用差值法,定量地确定矿井所在地自然地貌因素和采矿活动因素对植被NPP的影响并研究其影响程度。结果表明,不同空间尺度下神东矿区植被NPP和各个矿井地区植被生长状况均出现恶化的趋势,各个矿井恶化程度不同。不同地貌单元的矿区开采对植被NPP影响程度不同。不同矿井的不同植被类型受自然地貌和人为煤炭开采的影响各不相同。

摘  要：
Based on improved CASA model, the NPP(the net primary productivity) of vegetation in Shendong mining area was estimated to study the vegetation changes as a whole. The mine vegetation changes was analyzed in Daliuta, Bulianta and Yujialiang. A comparative study on vegetation growth between mining area and non-mining area was also carried out. At the same time, using the differential method, quantitatively measured the effects of terrain factors and mining activities on vegetation NPP and vegetation growth, so as to provide references for the policy making of protecting and managing the vegetation growth in mining area. The results showed that the growth status of vegetation NPP in Shendong mining area and vegetation NPP in different mines under different spatial scales was deteriorated, and the degree of deterioration of each mine was different. The degree of influence of mining in different landforms on vegetation NPP was different. Different types of vegetation in different mines were affected by natural geomorphology and anthropogenic coal.
