A Strategic Study On Ecological Low Impact Development Based On Landscape Ecology

Based on the theory of landscape ecology and the low impact development,this paper puts forward a new development strategy combining development and ecological protection with the study of eco-environmental problems caused by development and mitigation of development and construction.This study mainly includes four parts,Through the conclusions of each part,the development strategies of low-impact based on the impact of ecological development strategy are deduced and applied to the case of Dalian Xie Tun town to put forward the corresponding development recommendations:First of all,through the analysis of the low impact development theory and its actual case,the low impact development concept is divided into three parts: the reduction of human influence,the enhancement of the flexibility of the facility and the management of the external impact from the perspective of the positioning,sequencing and selection of the low impact development facilities.This paper analyzes the causes of the ecological environment problems caused by the development,and determines the feasibility of the low-impact development strategy to guide the ecological problems caused by the development.Under the guidance of the low-impact development concept,it is proposed to avoid the influence,minimize the influence,and manage the influence,management impact of the ecological impact of low development strategy.Then,the paper introduces the theory of patch-matrix-corridor theory,landscape pattern and function relation principle and landscape pattern index,and demonstrates the feasibility and the specific combination method of landscape ecology guidance ecological low development strategy.From the perspective of avoiding impacts,minimizing impacts,and managing the impacts of management,the factors that affect the ecological functions of the patches and the internal ecological processes of the patches are developed in the landscape pattern,which is rich in ecological functions and ecological impacts.Then,the ecological low-impact development strategy and landscape ecology are combined to solve the problem of determining the rich ecological function in the region from the perspective of landscape ecology,and propose the minimization effect of intensive optimization,relocation optimization and control optimization Strategy,management of the plaque material,to optimize the internal pattern of patches and the construction of ecological compensation facilities management impact strategy,the number of source management,pollution peak control,change the nature of pollution management strategy.Finally,the paper analyzes the landscape pattern of Xietun Town by using ENVI,GIS and Fragstats software,and puts forward the corresponding development suggestions according to the low impact development strategy proposed in this study,and makes an example demonstration of the results of this study.
