中文摘要	露天煤矿区植被退化问题日益严峻且对环境影响较大,确定植被退化主控因素并实施精准防治意义重大.为此,选取胜利与平庄露天矿区作为研究区域,以归一化植被指数( normalized difference vegetation index,NDVI)反映植被退化程度.同时,将熵权法引入灰色关联分析来构建熵权灰色关联模型,利用该模型分析NDVI值与挖损、压占、沙漠化和土壤侵蚀4个因素的关联性,根据各因素的关联性排序确定引起植被退化的主控因素.结果表明:( 1)胜利矿区不同因素熵权关联序排序为压占(熵权关联度为0. 294 7) >沙漠化( 0. 155 5) >挖损( 0. 151 0) >土壤侵蚀( 0. 119 3) ,平庄矿区则为挖损( 0. 169 3) >压占( 0. 163 7) >土壤侵蚀( 0. 150 5) >沙漠化( 0. 103 4) ;( 2)露天煤矿区植被退化最直接、最严重的影响因素是土地挖损、压占;( 3)沙漠化、土壤侵蚀2项因素对植被退化影响比挖损、压占因素小,但亦不容忽视.基于研究结果提出了相应措施,有助于避免植被退化防治的盲目性.
英文摘要	The vegetation degradation in opencast coal mines is increasingly serious,which causes impacts on the environment. Therefore,it is of great significance to determine the main factors of vegetation degradation so as to implement precision prevention. Shengli and Pingzhuang coal mines were selected as study areas. Normalized difference vegetation index ( NDVI) was employed to indicate vegetation degradation. The entropy weight was integrated with grey relational analysis to establish the entropy-grey relation model by which the relativity between NDVI and land excavation,land occupation,desertification and soil erosion were analyzed. The main factors of land degradation were determined based on the rank of relativity. The results show that: ( 1) The ranking of relativity of different factors in Shengli coal mine area is: land occupation ( 0. 294 7) > desertification ( 0. 155 5) > land excavation ( 0. 151 0) > soil erosion ( 0. 119 3) ; while in Pingzhuang coal mining area is: land excavation ( 0. 169 3) > land occupation ( 0. 163 7) > soil erosion ( 0. 150 5) > desertification ( 0. 103 4) . ( 2) The main factors of vegetation degradation in opencast coal mines are land excavation and land occupation. ( 3) Although the factors of desertification and soil erosion have less impact on vegetation degradation than land excavation and land occupation,they should not be ignored. Some measures have been proposed based on the results,which could help to avoid blindness during the prevention of vegetation degradation.
