摘要
为合理评价河流栖息地环境质量,应用多指标评价体系对凡河流域河流栖息地进行评价。结果表明：凡河流域河流栖息地综合指数值介于0.435～0.675;凡河源头及中下游河段的河流栖息地质量优于中游河段,夹河厂、树芽屯、凡河站及黄河子断面的栖息地质量处于较好等级,杨坟沟、榛子岭、老边台及小屯断面的栖息地质量处于一般等级,岱海寨断面的等级为较差。根据评价结果,提出了改善凡河流域河流栖息地环境质量的建议和对策。
In order to evaluate river habitat quality reasonably ,multi-index comprehensive evaluation system was used to evaluate river habit of Fan river basin .The results showed that the habitat comprehensive index value were 0 .435～0 .675 .The habitat quality of the source ,the middle and lower reaches of Fan rive was better than the middle .The habitat quality of Jiahechang ,Shuyatun ,Fanhezhan and Huanghezi sections reached good grade ,Yangfengou ,Zhenziling ,Laobiantai and Xiaotun sections reached common grade ,and Daihaizhai section was poor grade .According to the evaluation results ,some suggestions and countermeasures for improving the river habitat quality were proposed .
