| 摘 要： | 分析了河流作为重要地理要素和生态廊道在区域景观中的重要生态功能，以及河道建设中存在的主要问题。根据景观生态学原理，阐述了河道植物通过边缘效应、廊道效应和干扰效应可以对生物多样性产生积极影响。通过对10多个试点河段两年多的试验研究，提出河道建设要为植物措施创造条件，充分考虑生物多样性，恢复健康稳定的河道生态系统。认为河道生物多样性还需要考虑河流形态多样性，加强定位系统观测和注重研究植物群落演替规律。

| Abstract: | The construction of plant community is very important to an ecological river.The main ecological functions of river are analyzed as an important geographical element and an ecological corridor for a regional ecosystem.By assuming vegetation measures to be a positive artificial disturbance,biodiversity can be effectively improved by edge effects and corridor effects.It is proposed that in river construction,ecological functions should be taken into account.Biodiversity conservation demands on environment sho... |
