| 摘 要： | 从实行金属矿床穴山雪地质环境评价出发,对大量地质信息进行转化并归纳出4个地质环境因子,根据不同的资料类型采用不同的评价方案:对无空间属性的资料(16个地质环境指标),根据其影响程度采用“五分制”进行评测;对有空间属性的资料,通过建立评价模型并采用经验和计算法进行赋权后,利用GIS进行空间分析,最终获得矿床(山)环境质量综合评价结果。

| Abstract: | In order to evaluate the environmental impacts of metal deposits,plenty of geological information is transformed and classified into four geo-environmental factors.Based on the types of data,different approaches are used to assess the data:for the data (16 geo-environmental indices) without spatial attributes,the five-point grading scale is used to assess the influence on the environment;for the data with spatial attributes,including the elemental distribution in soils and stream sediments,GIS is used for the spatial analysis the data after establishing the assessment model and using the empirical and calculation methods to weight their impacts.Finally,integrated assessment results are obtained for the environmental quality of mineral deposits (mines). |
