摘要
利用层次分析法(AHP法)对影响石嘴山市生态环境的因素进行评价.结果表明,影响其生态环境的主要贡献因子为植被覆盖率、污染物排放强度、气候因子和水文条件等.根据各评价指标所代表因子对生态环境质量的贡献,结合当地实际情况,提出加强封山禁牧、实施煤炭开采塌陷区生态修复、调整工业结构、适当增加森林覆盖率和加强环保执法等改善生态环境的建议.
The ecological environment of Shizuishan was evaluated with Analytic Hierarchy Process （AHP）. The results show that the most important factors influencing the ecological environment are coverage rate of the vegetation, the intensity of pollutants, climate, water resource and so on. According to the contribution of each index and the local actual situation of Shizuishan city, the suggestions to improve the eco-environment, such as strengthening the forbidding grazing, implimenting the ecosystem restoration within the subsiding area which caused by the coal mining,adjusting the industry structure,increasing the forest cover rate as well as strengthening the enforcement of environmental protection law are proposed.
