Spatial Utilization Of Urban Fringe Zone Of Lianhua Lake In Dazhou City Based On Ecological Pattern Of Wetland

Edge area of city wetland of cities have higher compared with other wetland ecological service value,on the one hand,with the improvement of living standards,people demand for the service function of wetlands in urban fringe area increasing,people pay more attention to the service of wetland utilization value;On the other hand,the expansion of the city squeezes the natural space of the ecological wetland,and the ecological protection situation of the lake reservoir wetland in the marginal area is severe.There is an urgent need to find a fringe area library lake wetland protection and rational utilization of the coordinated development of the solution space,on the basis of the overall ecological function of wetlands protection,improve the utilization efficiency of wetland of land resources.By collecting the wetland ecological landscape related research data and theoretical method,with the lotus lake area as the research object,looking for the lake edge area of library by using the coordinated development of wetland protection and space path planning method and technology.It is proposed to resolve the contradiction between urban spatial strategic development needs and wetland protection,and promote the stability of wetland ecosystem and the sustainability of exploitation and utilization in marginal areas.On the basis of the wetland ecological basic theory,draw lessons from successful experience at home and abroad,to dazhou lotus lake district space around use of coordinated development to study,is proposed to solve the lotus lake area of three key questions:(1)urban fringe area after the expansion of lake environmental capacity problem,(2)based on the principle of water sensitivity is the lotus lake area space matching problem,(3)the internal functions of the lotus lake area coordination problems.This study analyzes lotus lake from the following six aspects.First,by using water balance analysis and evaluation method of ecological footprint,evaluate the lotus lake reservoir area ecological carrying capacity in each scenario,guide the determination of environmental capacity building capacity problems of the construction of the library can determine the lake.Secondly,using the principle of landscape ecology and ecological sensitivity evaluation,the ecological security pattern of wetland is delimited to solve the spatial matching problem of lotus lake area.Thirdly,using landscape analysis methods such as landscape evaluation,the spatial framework of leisure and recreation is determined to increase the function of ecological services.Fourthly,according to the principle of environmental influence and correlation,the development function composition and environmental requirements are determined.Fifth,based on the ecological security pattern of wetlands and in accordance with the principle of minimum interference,the optimal space utilization pattern is constructed by matching leisure and recreation space and developing functional space.Sixth,for the fragile sensitive area or in the wetland ecological security pattern,as well as the development and utilization of the disturbance can be weakened after sensitive to anchorage and repairing,puts forward management measures to cope with change,to ensure the overall stability and development and utilization of the wetland ecological sustainable coordination.Therefore,the framework of this article is:Chapter 1: this research elaborates the background and significance of the topic selection,explores the feasibility of the paper through the method of literature review,and determines the research thinking of the paper.Chapter two: to analyze the basic theory of wetland ecological protection and the successful case of conservation developmentChapter three: using water and water balance and ecological footprint method,the ecological carrying capacity of lotus lake wetland was evaluated and its environmental capacity was determined.Chapter four: using the principle of landscape ecology and ecological sensitivity evaluation,delineate the ecological security pattern of wetland.Chapter 5: the framework of leisure and recreation space is determined by landscape analysis methods such as landscape evaluation.According to the principle of environmental influence and correlation,the environmental requirements of each development function composition level are determined.Based on the ecological security pattern of wetland and according to the principle of minimum interference,the optimal space utilization pattern is constructed by matching leisure recreation space and development function space.Chapter 6: for the fragile sensitive area or in the wetland ecological security pattern,as well as the development and utilization of the disturbance can be weakened after sensitive to anchorage and repairing,puts forward management measures to cope with change,to ensure the overall stability and development and utilization of the wetland ecological sustainable coordination.Chapter 7: summarize the results of the study on the spatial use of urban fringe areas in the ecological pattern of lotus lake and reflect on the shortcomings.
