The Water System Planning And Design Research Of The Wetland Park In The Loess Plateau

In recent years, people pay more attention to the natural environment. The wetland park rises gradually. The water system planning in the wetland park is becoming more and more widely. This paper combines the particularity of the loess tableland wetland park with the theory and method of landscape ecological planning, and using GIS analysis method, to study the particularity on loess units. Finally, summarize the basis strategy for water system planning of the Loess Plateau.The research of this paper is divided into six chapters. The first chapter is introduction; Chapter Two summarizes the reviews of the loess tableland, wetland park planning and design, water system planning and design, and then summarizes the problems existing in the theory and practice; The third chapter discuss the planning specificity. Summarize the ecological characteristics from the specificity of the Loess Plateau, namely soil erosion and drought, and then summarize the planning particularity in the Loess Plateau, namely soil and water conservation and rain flood management; Based on the particularity, the fourth chapter puts forward the loess platform tableland area drainage planning strategy planning ideas and GIS technical support from the macro level, the meso level and the microscopic level; Fifth chapter analyse water system planning strategy, from the three aspects: present situation, the landscape pattern analysis and evaluation of the results of the analysis through the river wetland park, finally concluded the water system planning strategy.This paper puts forward the loess tableland area drainage planning strategy from the macro, meso and micro three levels respectively. And according to the loess tableland area ecological environment particularity, namely the water loss and soil erosion, put forward the security pattern of soil erosion, as the macro guidance for soil and water conservation strategies.
