The Research On Landscape Construction Of Seasonal Rivers Under Ecological Restoration In Northern China

With the continuous development of China's modernization,to meet the various needs of people on the river,carried out lots of river construction projects.Because of the ecological function of river channel ignored,many river channels,causing serious damage to the river ecosystem,river landscape destruction is serious.How to improve the ecological environment of the river and the sustainable development of river landscape has become the focus of current research.The study of river landscape based on ecological restoration is earlier in foreign countries,relevant research results are numerous,but the characteristics of the river regions in China is different,existing foreign research results are not completely applicable.Although there are domestic relevant research,it is still in its infancy,also existing a lot of academic debate.In this paper,the prominent environmental problems of seasonal river in North Chi na as the research object.Through the investigation on the present situation of ecological landscape and typical northern seasonal rivers,the problems existing in this kind of riv ers.Such as serious degradation of river ecosystem,serious hardening of river channel,serious water pollution,and dry intensification.Study on the river successful constructio n cases,inspired and reflect its shortcomings.Through the existing problems and the exi sting problems in the construction of such rivers,the establishment of the north seasonal river landscape construction ideas,goals and principles under the function of ecologicalrestoration,from four dimensions of river space in vertical and horizontal,vertical and time put forward specific methods of landscape construction.Taking Qingjian River as an example,the practical application,provide theoretical guidance and reference for the scientific design of the river landscape construction,to realize the construction mode of seasonal river landscape in the north of China with the unification of ecological benefit,social benefit and economic benefit.
