Studies On Ecological Landscape Belt Of Weihe River Planning And Design In Yangling Shaanxi

Rivers is an important part of urban landscape, bearer of city environment and resource and factor of city ecological environment. It has various functions: ecology, landscape and society, which of the ecological function mainly embodied in flood control, drainage, transportation and water supply in basic functions and climate modulation, environment purification, biodiversity protection, water conservation and environment beautification in ecological functions. With the acceleration of urbanization, urban river emerged the problem of water quality deterioration and ecological unbalance, which seriously affected the quality of urban ecological environment. So restoring the ecological function and natural characteristics of urban river is imminent.Based on the principle of landscape ecology, recovery ecological, this paper referred to the advanced theory and practice experience of ecological river governance both at home and abroad and investigated the situation of Wei He, attempting to find out the construction problems and seek the corresponding solution. Here we discussed the Wei He ecological landscape design mainly from the aspects of the river bank, the flood land and vegetation, and reached the following conclusions:1. Through the method of protecting or restoring of river natural form and geomorphology, maintaining the river continuity and reconstructing deep pool– ford, the ecological function and natural characteristics of Wei He was restored.2. Using the method of the ecological riparian design, ecological river and wetland restoration, vegetation restoration, open space construction, build natural and ecological river natural landscapes to restore its ecological function and satisfy people enjoying water and recreational needs, exerting the various functions of river.3. In the ecological landscape design of Wei He, pay attention to follow the natural succession law, reducing human interference to the influence of natural process; Using the ecological engineering measures, reduce artificial landscape and human activities on the influence of natural landscape.4. Using the local landscape plant enriched the river landscape to be natural, amusement and features.5. Strengthening regional cooperation and establishing ecological agencies and system of Wei He management, from regional ecological restoration governance perspectives.
