摘要
河湖健康评价工作不仅是推动河湖长制从“有名”到“有实”转变的关键环节,更是实现河湖管理精细化的重要途径。以海南岛典型河流为研究对象,基于相关规范并结合河流的自身特性,构建了全面的评价指标体系,开展健康评价工作。评价结果显示河流总体健康状况表现良好,但仍有部分指标暴露出不同程度的健康缺陷:大中型河流在物理结构和水量方面存在较为明显的健康问题,如纵向连通性下降、生态流量不足以及流量过程变异程度加剧等;而小型河流则在水域空间、水质以及生物多样性等方面表现出更为显著的健康受损状况。基于评价结果,提出有针对性的措施和建议,旨在指导河流治理工作有序进行,促进河流恢复健康生命。
The health evaluation of rivers and lakes is not only a key link in promoting the transformation of the river and lake chief system from“nominal”to“practical”,but also an important way to achieve the refinement of river and lake management.Taking typical rivers in Hainan Island as the research object,a comprehensive evaluation index system was constructed based on relevant standards and combined with the characteristics of the rivers,and health evaluation work was carried out.The evaluation results show that the overall health status of the rivers is good,but there are still some indicators exposed to varying degrees of health defects.Specifically,large and medium-sized rivers have significant health issues in terms of basin physical structure and water flow,such as decreased vertical connectivity,insufficient ecological flow,and increased variability in flow processes.Small rivers,on the other hand,exhibit more significant health damage in terms of river space,water quality,and biodiversity.Based on the evaluation results,targeted measures and suggestions are proposed to guide the orderly progress of river management work and promote the restoration of healthy life in rivers.
