中文摘要:
      河湖健康评估是评价河湖健康现状、诊断河湖健康问题、拟定河湖保护与修复策略的重要手段,对维护河湖生态健康、维持流域生态系统良性具有重要意义。本文对河池市最重要的河流之一——龙江河,从水文完整性、物理结构完整性、化学完整性、生物完整性、社会功能完整性5个方面,全面评估其健康状况。结果表明:河池市龙江河总体处于健康状况,评估赋分72.8分,但仍存在进一步改善的空间。主要问题包括:天然流量过程被改变;河岸带存在人工扰动情况,河道被重重阻隔;流域开发活动可能增多,水污染潜在风险仍然存在;河流生物状况不清,底栖环境状况不容乐观;河流管理保护状况与公众需求仍存在一定差距。
英文摘要:
      The health assessment of river-lake is an important means to evaluate the health status and the health problems of river-lake, and draw up protection and repair strategies of river-lake. It is of great sig-nificance to maintaining the ecological health of river-lake and realizing healthy circulation of watershed eco-system. The Longjiang River is one of the most important rivers in Hechi city. The research evaluated the health status of the Longjiang River comprehensively in Hechi city in terms of hydrological and water re-sources integrity,physical structure integrity,chemical integrity,biological integrity and social service func-tional integrity. The results show that the health assessment score of the Longjiang River in Hechi city is 72.8,which could be reformed better. There are such problems as the natural flow process changing,artifi-cial disturbance in the riverbank zone, the river heavily blocked, basin development activities increasing, potential risks of water pollution, the biological condition of river not clear, the poor condition of benthic environment and an existing gap between river management and protection and public demand, which need to be addressed
