Research On Central Unban Area Ecological Landscape Planning Of The Northwest District Sesonal River

City rivers are not only the lifeline of our survival,but also the fundamental economic and cultural prosperity.However,with the development of the city,The urban rivers are affected by natural and artificial factors,many rivers often began to change to seasonal river.In order to meet the demand of city flood control,people began to cut off the river and make it to be straight The bund is taken measures to the revetment in the structure.Therefore,in this context,the article launched a study on the ecological landscape planning of the central section of the seasonal river.This paper takes the river of the central city section as the research object,using the literature research,the case analysis and the field investigation as the research method,then it finds out the ecological structure and characteristics of the seasonal river and reveal the best planning strategy of the ecological landscape of the seasonal river center.The First of all,this paper sets out the theoretical basis for the study by sorting out the existing theory and typical examples of seasonal river ecological landscape planning and river channel construction in the central urban area,identifying the research direction and focusing on solving the problem.Secondly,the paper summarizes the problems which are the the current situation of water landscape,the present situation of planting landscape and the present situation of the artificial landscape construction,and analyzing the causes of the seasonal rivers.Finally,the ecological landscape planning strategy of the seasonal river center is put forward by studying the ecological flood control planning,the ecological landscape planning,the plant planting planning and the artificial hard landscape planning in the seasonal river center.In addition,it uses the case of Juhe Yaozhou urban section as a case study,this paper analyzes the current river construction and existing problems,and puts forward the corresponding planning strategy from the perspective of ecological landscape planning,so as to provide the theory for the ecological landscape planning of the seasonal river center guide.
