Assessment On Ecological Health Of Ladscape And Optimization Strategy Of Sun Island Scenic Area

Investigation and evaluation of scenic resources is the first step to correctly understand the situation and value of scenic resources,to verify the grade of scenic areas,and to do a good job in planning and management.Strict protection,overall planning,adapting measures to local conditions,highlighting characteristics,low carbon and energy saving are the overall requirements of scenic area planning.In recent years,according to the requirements of the state,most scenic areas at all levels have worked out general plans to guide the development of various undertakings.Some problems exposed by urban scenic areas in the process of rapid urbanization deserve our consideration.How to put forward a scientific and reasonable planning and management method from the planning level,alleviate the contradiction between natural ecological environment and urban artificial construction,and realize the harmonious coexistence of urban scenic areas and urban development is the aspect that the planners and designers should strengthen their research.Based on the results of landscape ecological health assessment,the landscape optimization strategy is an effective way to solve the above problems.Firstly,this paper theoretically analyses the problems encountered in the development and process of urban scenic areas.In the process of damage and degradation of landscape ecosystem,landscape ecology and recreation theory are used to solve these problems.After summarizing the previous research foundation,this paper selected the Sun Island scenic area as the object of empirical research,applied remote sensing(RS),geographic information system(GIS)technology to evaluate the landscape ecological health of the Sun Island scenic area,and made statistics on the corresponding results,and took these results as the basis for further planning of the scenic area.Based on the evaluation results and successful experience and methods,the optimization strategy of Sun Island scenic area is put forward.It is hoped that it will be helpful to the sustainable development of scenic areas and provide reference for the evaluation and optimization of landscape ecological health of the same type of urban scenic areas.In this paper,the research focuses on the following two aspects:(1)With the support of remote sensing and geographic information system,the information sources are extracted and processed through the interpretation and analysis of satellite remote sensing images.Based on the basic theory of landscape ecology and the principles of landscape ecological planning,the spatial pattern of landscape was analyzed and the landscape ecological health was evaluated.(2)Based on the successful experience and methods,the landscape optimization strategies of Sun Island scenic area are put forward from macro and small scales respectively.This paper probes into the problems existing in the planning and construction of the scenic area of Sun Island,and based on the research results,carries out the corresponding special planning,explores the scientific and rational planning approaches and methods of the scenic area,and coordinates the land use,landscape protection and tourism service facilities of the scenic area,so as to realize the sustainable development of the scenic area.
