【摘要】 论文改变前人的平均权资源环境安全评价方法,提出了具有4个层次19个要素指标的区域资源环境安全评价指标体系,采用层次分析法和线性加权综合评价模型进行区域资源环境安全状态进行评价。结果表明,桂西北喀斯特山区资源环境安全指数仅为0.77,处于不安全状态,有81.8%县市,76.9%的国土面积处于不安全状态,其不安全区域分布与喀斯特分布具有高度的空间耦合性。研究区大多数指标安全值均很低,有14个指标值处于很不安全状态,占总指标数的73.7%,有8个指标值接近于零,即42.1%指标处于极端不安全状态。评价指标具有良好的指示功能,为区域资源环境安全调控和管理策略的制定提供很好的依据。更多还原

【Abstract】 The paper inpoved the average-weiht method for resources-environmental evaluation,and put forward a new index system which contains four level structure with nineteen indicators,and using the analytic hierarchy process(AHP) and the linear weighted model to calculate and evaluate the resources-environmental security status for the karst mountain areas in northwest Guangxi.The result shows that:(1) The security index of the region is 0.77 which is at the insecurity level.There are 81.8% of the total counties and 76.9% of the territory area in the region at the insecurity level.(2)The insecurity level distribution area highly fits close to the karst areas in the region,it shows that the karst envirnment has a very strong effect on the region resources-environmental security;(3)The values of most indicators in the region are very low.There are fourteen indicators which the vaules are at the insecurity level,and the values of eight indicators are near zero,it means that there is 42.1% of the total indicators which is at the very insecurity level.The index system has a good indicating functions for regional resources-environmental security regulation.更多还原
