【摘要】 针对河道生态景观受地域影响的问题,以典型季节性蜿蜒河道——羊肠子河道治理为例,对现状河道生态需水量、蜿蜒性、连通性及景观建设现状进行分析。结果表明河流的蜿蜒性、连通性及现有景观呈现效果均较差,生态景观欠缺。为此,提出"在保证河道自身稳定健康的基础上结合周边土地利用情况构建生态景观"的生态整治措施。通过维护生态基流与建设护岸栖息地以维护河道的稳定健康;通过优化乡村便道以及建设沿河生态景观以防风固沙、涵养水源、保护物种多样性,从而增强河道连通性、打造生态走廊、优化生态景观、健全生态平衡、改善环境。更多还原

【Abstract】 In view that the river’s ecological landscape is affected by the regional conditions,we carry out an analysis and evaluation of it from multiple aspects including the river’s ecological water quantity,meandering state,connectivity,as well as landscape construction based on a typical seasonal meandering river,the Yangchangzi River.The result reveals that the meandering state,connectivity,and landscape presentation of the river are all poor and it is lack of ecological landscape. So,we put forward the measure of constructing the ecological landscape under the prerequisite of guaranteeing the river’s stability and health and considering the surrounding land utilization: by maintaining the ecological base flow and constructing the bank habitat to ensure the stability and health of the river,by optimizing the rural road and constructing the ecological landscape to realize the windbreak & sand fixation,water conservation and protect species diversity,so as to strengthen the connectivity and ecological balance of the river,create an ecological corridor,optimize the ecological landscape and improve the environment.更多还原
