摘要
健康的河流是指在相应时期其社会功能与自然功能能够均衡发挥的河流,其标志是:具有通畅稳定的河床、良好的水质、可持续的河流生态系统和适量的河川径流。河流健康指标应能够基本反映河流自然功能,但种类和数量因河而异;健康标准的确定要充分考虑河流自然功能和社会功能均衡发挥的需要和河流背景条件的变化。人类过多抽取河川径流和开发水电、不当地调控洪水和泥沙、过多向河流排污和改变关键物种栖息地环境的活动,均会对河流健康造成伤害。
A healthy river means that it can bring its natural function and social function into play in a relevant period.The signs are as follows: It has unblocked and permanent bed,good water quality,sustainable ecosystem and an appropriate amount runoff.The index of river health can basically reflect the natural function of a river and the category and quantity varies with each river and;the determination of healthy standard should fully consider the requirements of natural function and social function development and the variations of river background condition.All the human activities of overuse of runoff,overdevelopment of hydropower,inappropriate regulation and control of floods and sediment,overmuch discharge of polluted water to the river and the changes of habitat environment of key species would harm the health of a river.
