河流地貌特征多样性的保护

Protection of the diversity of river morphology character

河流作为一个有机的生态整体与生物多样性共存,构成了一种相互耦合的生态系统。河流丰富的地貌形态为流域生物多样性创造了很好的条件,是生物群落多样性的基础。现代水利工程应该克服对河流形态的多样化重视不足和忽略生态环境的缺陷,在治河过程中,尊重河流流域的自然状况,尊重各类生物的生存权利;认识并遵循河流地貌演变的客观规律,逐步完善河流生态工程建设措施;保护河流地貌形态特征多样性,为生物的生长、繁殖、栖息提供条件,达到保护河流生态系统多样性,维持河流系统健康的目的。

As an organic zoology unity, river coexists with biology diversity forms a coupling ecosystem. The abundant morphology character is the basis of the diversity of bio-communities and creates the good condition for the diversity of river biology. The paper presents that modem water projects should take more attentions to diversity of river morphology and bio-environment which was not be considered in old water projects. We should respect the natural condition of river and the biology survival right, research and respect the impersonality rule of the river morphology evolution when we are building water projects. The paper also suggests that the diversity of river morphology be protected for the plants and animals＇ growing, reproducing and inhabiting in order to get the aim of protecting the diversity of river eco-system and keep the health of river system .
