中文摘要：

本文根据我国煤炭开采区的特点，修改、优化了HEA的部分参数和代数模型。运用2007年“中国生态系统生态服务价值当量因子表”，构建了求解煤炭开采区受损植被受损量、补偿量、补偿规模的HEA模型。运用模型处理、分析了相关统计与调查数据，计算出榆林神府煤炭开采区草地生态服务功能价值损失量、补偿量和补偿规模。认为，2004年-2008年，榆林神府煤炭开采区草地生态服务功能价值的损失量逐年上升，受损植被应补偿量逐年扩大；榆林神府煤炭开采区应当把从荒漠到林地作为实现受损植被生态服务功能转换的主体方案，把从农田到草地、荒漠到草地、农田到林地作为实现受损植被生态服务功能转换的3种补充方案。

英文摘要：

Ecological assessment for impaired vegetation in coal mining areas and quantification of the impairment compensation play a prominent role in implementing ecological compensation. In this paper, the authors modified and optimized certain parameters in the HEA method and relevant models based on characteristics of China＇s coal mining areas with the objective to quantify vegetation impairment and ecological compensation for Shenfu coal mining areas in Yulin County. In particular, the authors selected the factors of instantaneousness and slowness to improve the estimation. Moreover, the mean of the impairment quantity of ecological service functions and the compensation amount were introduced both at the beginning and the end of the study period. Furthermore, several related factors were also considered, such as the factors influencing the extent of the impaired vegetation and the factors affecting restoration degree as well as the factors affecting population growth rate. In the light of ＇the 2007 Table of indicators of ecological systems service functions in China＇ and the HEA models, compensation quantity and compensation scale of vegetation in coal mining areas were estimated. Losses in value of ecosystem services for grassland, compensation quantity and compensation scale were also calculated. The results indicated that in Shenfu coal mining areas the function value in the field of grassland ecosystem services was progressively decreasing whereas the nominal amount of the compensation for impaired vegetation was increasing year by year during the period 2004-2008. It was suggested that conversion of desert into forestland could be an effective way to achieve the goal of rehabilitating ecological service functions for impaired vegetation. Meanwhile, conversion of farmland into grassland, desert into grassland and farmland into woodland could also be adopted as complementary measures for ecological compensation in the coal mining areas. The study also indicated that it is operational and effective to use th
