济南市南部山区河流生态系统健康评价研究

Study on Health Assessment of River Ecosystem in Southern Mountain of Jinan City

根据济南市南部山区的实际状况建立了一套河流生态系统健康的指标体系,并进行了河流生态健康评价。指标体系包括水质指标、水文指标、河流形态指标、滨岸带指标、河流生物指标、水体社会功能六大类。二级指标通过分级描述进行打分,得出对应一级指标得分,根据权重进行计算,得出研究区域生态系统健康状况的分值。结果表明,锦阳川干流生态状况较好,支流存在一定问题,锦绣川水库东侧整体生态状况较好,西侧生态状况相对较差,部分点位存在较为严重的生态风险。

According to the actual situation of the southern mountain in Jinan of Shandong Province,a setof index system for river ecosystem health was established and river ecological health assessment was carried out.The index system includes six categories:water quality,hydrology,river form,coastal zone,biology,and social functions.The secondary indexes are scored by hierarchical description and then calculated according to the weights to get final scores.The assessment results showed that the ecological health situation is generally good,and some points have serious ecological risks,which need to be focused on.
