在近些年多发的洪水灾害及河流污染中,人们已经逐渐认识到大范围的修建水泥防洪堤、斩除滨水植物、覆盖河流的做法已严重违背自然规律。随着人们对生态、环保意识的加强,不乏有大量自然型护坡的生态河道出现。然而针对不同的护坡处理手法应该选用何种滨水植物进行有效、合理的布置,才能提高河道的自净能力、具备一定的防洪能力及改善小气候的能力呢。本文将就其功能、选用原则、选用场所进行探讨。 In the flood-prone floods and river pollution that have taken place in recent years, people have come to realize that a large-scale construction of flood-control levees and the removal of waterfront plants and river cover have come to a serious violation of the laws of nature. As people’s awareness of ecology and environmental protection strengthens, there are many ecological rivers with a large number of natural slope protection. However, in order to improve the self-purification capacity of rivers and rivers, and to have certain ability of flood control and microclimate improvement, what kinds of waterfront plants should be selected for effective and reasonable arrangement for different slope protection methods? This article will discuss its function, selection principle, selection place.
