河道整治中的生态环境问题与生态协调的河道整治
Ecology environment in river harness and the river harness based on ecology coordinate
摘要
Abstract
In order to maintain the ecological environment of rivers and coordinate river harness with demands to river ecology,the relationship between river morphology and river ecosystem,as a priority,has been analyzed.Some important cases have also been analyzed such as the influence on river ecological environment caused by change of channel or washland,the disturbance to river alluvial process and coercion on river biodiversity due to traditional river training.The river training principles,regulation idea,comprehensive improvement model and methods have been discussed based on the ecological harmony.The plans put forward for modern training river should be given to meet the demand of river ecosystem balance.It means that interference to the river boundary should be controlled with "moderate",and eco-engineering measures must be adopted.Two typical cases show that by adopting the new training ideal and method based on ecological harmony,Simpson biodiversity index and assessing value for river structure and function have been obviously improved in the rivers,where pervious ecological revetment has been used,marsh protecting region has been set up in the river washland,ecological transition region has been designed between water and land,and green way as well as some landscape measures have been built along the rivers two sides.The new ecological engineering material has good ability for ecological restoration,good flexibility and overall stability of structure,which is the main technical support for river ecological harmony.关键词
