摘要
通过设定疏勒河流域生态环境评价指标和环境质量刻度,采用主观概率累和法,对疏勒河流域天然植被退缩量、河湖萎缩与消亡、区域次生盐渍化、土地沙化、水土流失、水体污染六大子系统进行评价.结果表明:疏勒河流域生态环境现状总体"一般",局部地区生态环境恶化,存在诸多隐患,在流域开发决策中应给予足够重视.
By enacting index and environmental quality scale of eco-environment in the Sule River basin, based on cumulative subjective probability method, six sub-systems （the degradation of natural vegetation, shrinkage and wither-away of rivers and lakes, regional soil secondary salinization, land desertification, soil and water loss, water pollution） were evaluated. The results show that the status quo of ecological environment in the Sule River basin is normal （third grade）. However, there are many problems to be resolved, to which more attention should be paid in the future develop decision-making.
