Discussion On Ecological Design Method Of Urban River Landscape In Lixiahe Area Of Jiangsu

In recent years,with the rapid development of China's urbanization process,urban river system is facing a huge impact.With the significant increase of wastewater discharge,the lack of ecological base flow,the decrease of ecological regulation function and the failure of landscape quality to meet the needs of people,urban rivers fail to play their role as "ecological core" in urban development.How to take landscape ecology as the breakthrough point,while giving full play to the flood control and waterlogging functions of urban river courses,and at the same time,protect and restore the ecological environment of urban rivers and create urban waterfront landscape,has very important practical significance.In this paper,the theories and methods of river landscape ecological construction at home and abroad are combed,and the successful cases of typical urban river landscape ecological construction are deeply analyzed and studied.According to the characteristics of urbanized polders of lixiahe areas in Jiangsu province,landscape ecological construction main method of urbanized polders of lixiahe areas has carried on the induction summary.The paper put forward a method for the evaluation of the landscape ecological design scheme in the urbanized polders,and develops a visual evaluation module.It has been applied to the treatment project of Nanchengzi River in Gaoyou City,and a good effect has been achieved.This paper summarizes and puts forward the design ideas and evaluation methods suitable for the river landscape ecological construction in urbanized polders of lixiahe areas in Jiangsu province,which can provide reference for the river landscape ecological construction schemes in Jiangsu province and the same type of areas in China.
