Study On Protective Utilization Of Gan River Basin In The Piedmont Of North Qinling Mountains Based On Eco-service Evaluation

Since the promulgation of ecological protection policy,ecological damage in the piedmont of north Qinling Mountains has been temporarily alleviated.However,in the process of social and economic development,there are also many problems in the piedmont of north Qinling Mountains,such as protection,non-development,waste of resources in the present situation,weak public participation,small ecological protection,difficult operation of policies,backward economy,etc.The relationship between its protection and development is increasingly tense.In this context,based on the scientific framework of landscape sustainability,the theory of public participation and eco-service evaluation,combined with the current situation investigation,data collection and questionnaire survey,this paper evaluates the eco-services of the Gan River basin as the object of study.Based on the analysis of the ecological process affecting the performance of eco-service in the Gan River basin,the protective utilization model based on the evaluation of eco-service is put forward.This study is divided into six chapters.The first chapter is the introduction,mainly to research background,research object,research hypothesis,research purpose,research significance,research summary and research frame have carried on the comb and explanation.The second chapter is related concepts and theoretical research.Firstly,the related concepts are defined in this paper.Secondly,the scientific extension framework of landscape sustainability is constructed through the study of the formation mechanism of eco-services and it is introduced and analyzed that the theory of publicparticipation and the construction of eco-service evaluation system.Finally,based on the above three theories,this paper integrates the operational steps from theory to practice.The third chapter is the evaluation part of the eco-service in the Gan River basin,which is the ‘evaluation model' part of the technical route in this study.This chapter first introduces how to identify the pattern,process and service of the Gan River basin,then constructs the relationship between ‘pattern,process,function and service',finally evaluates and identifies the eco-services in the Gan River basin.The fourth chapter is the analysis of the mechanism of ‘service-process' in the Gan River basin,and the part of the ‘analytical model' of the technical route.Based on the evaluation results of eco-services in the Gan River basin,the ecological processes affecting the performance of eco-services are analyzed.The fifth chapter is the study of the protective utilization in the Gan River basin.The study of protective utilization in this chapter is carried out through the two-step operation of protection and then utilization.Then,the optimization management measures of eco-service oriented model are supplemented.The sixth chapter is the conclusion,the insufficiency and the prospect part,summarizes the main research conclusion,the research innovation point,the research insufficiency and the extension direction.The innovation of this paper is as follows: Firstly,the evaluation system of eco-service in the Gan River basin is constructed.Under the background of relevant theory research on eco-service and evaluation model,this paper constructs the evaluation model of eco-service in the Gan River basin based on the clue of‘pattern-process-function-service'.Secondly,the protective utilization models based on eco-services evaluation are proposed.Protective utilization is to achieve the goal of conservation and restoration through pattern optimization first,then to seek the development modes that promote each other with eco-services.
