Study On Ecological Evaluation And Planning Of National Park Of China Based On Invest Model Method

In recent years,with the increasing demands of tourists for leisure culture,ecological tourism and recreation,the demand for tourism of National Park of China with beautiful environment and rich scenery sources is also increasing.In the process of National Park of China utilization,how to jointly promote the environmental benefits,economic benefits and social benefits,maintain the coordination between ecological environmental protection and utilization,has become the main problem in the planning of National Park of China.Ecological benefit is the main criterion to analyze the relationship between environmental benefit,economic benefit and social benefit.The study on the concept connotation,index classification and evaluation method of ecological benefit provides a unique perspective for National Park of China planning.The development of concepts and model methods of ecosystem service function and landscape performance provides theoretical and methodological guidance for the evaluation of ecological benefits in National Park of China.This paper makes a comprehensive study of the relationship between ecological benefit evaluation and planning methods of XiShan National Park of China from two aspects of theoretical research and project practice.Theory research mainly combs the concept,the development process and evaluation method of ecological benefit,and the concept,classification and planning method of National Park of China planning.Besides,the research studys the concept,development,evaluation system and evaluation tools of the ecosystem service function,as well as the concept and practical application of the landscape performance.Based on this,and combined with the practice in the detailed planning of XiShan scenic spot,XiShan National Park of China ecological benefit evaluation model is constructed.In terms of project practice,first of all,with the technical aid of Gis,the InVEST model method is used as the main method to systematically evaluate the ecological benefits of the current situation of XiShan National Park of China.Then,according to its score and spatial distribution,the main problems existing in the current situation are summarized.Secondly,by referring to the existing parametric planning methods of National Park of China,and based on the current ecological benefit evaluation,the spatial strategies,zoning planing,landscape conservation planning,water system planning,land use coordination planning and other planning strategies are planned.Finally,through the comparison of ecological benefit evaluation before and after planning,the influence of planning strategy on ecological benefit is analyzed,which can provide theoretical and methodological guidance for planning of National Park of China.By studying the ecological benefit evaluation and planning method in XiShan National Park of China,this paper hopes to expand the research field of ecological benefit evaluation and strengthen the consideration of ecological security factors in the planning of XiShan National Park of China,which will be helpful for the protection and utilization of National Park of China.
