Effects Of Terrestrial Wildlife Conservation On Biodiversity And Countermeasures

Biodiversity is made up of species diversity,genetic diversity and ecosystem diversity.Terrestrial wildlife is an integral part of thousands of species.Therefore,the protection of terrestrial wildlife resources is an important part of biodiversity conservation.A large range of terrestrial wildlife reductions and loss of biodiversity make the ecosystem out of balance.Therefore,it is of great practical significance to combine terrestrial wildlife protection with biodiversity conservation and improve the efficiency of biodiversity conservation.This paper mainly uses the method of qualitative and quantitative analysis to study.In the first chapter,it introduces the background,the significance,the review literature,and the technical route of this paper,and clarifies the direction of the paper.The second chapter gives a brief account of the core concepts and theoretical basis,it provides the implications of terrestrial wildlife,habitats and biodiversity,and introduces the ecological economics theory,the causal path analysis theory,the biodiversity evaluation theory and the PSR evaluation framework,laying the foundation for subsequent research.The third chapter mainly describes the status quo of terrestrial wildlife resources,its main threats and related protection policies,laying the foundation for qualitative analysis and empirical analysis.Based on the in-depth description,the fourth chapter summarizes the relationship between terrestrial wildlife protection and biological diversity by causal path analysis,paving the way for the follow-up of empirical research and putting forward countermeasures.The fifth chapter is based on the fourth chapter qualitative analysis of ideas and their content,takes Dafeng National Nature Reserve as an area for empirical analysis,constructs the PSR biodiversity evaluation index system,and uses the analytic hierarchy process to determine the index weight,and then evaluates the biodiversity of the area based on the relevant line graphs drawn.Finally,combined with the results of qualitative analysis and empirical analysis,it puts forward the countermeasures and suggestions of biodiversity conservation.The qualitative analysis of this paper is based on the deep description of terrestrial wildlife resources in different habitats,it uses the causal relationship path analysis to draw the following conclusion: human economic development has had a significant impact on terrestrial wildlife and its habitats,resulting in a reduction in the number of terrestrial wildlife and affecting its population distribution,which ultimately leads to a reduction in biodiversity.From the perspective of the food chain,it is concluded that the lack of low-level food sources will inevitably penetrate into the second and third tier consumers and ultimately affect the biodiversity.At the same time,the key factors of different types of habitats are necessarily different,and the key factors to identify habitats are of great significance to improve the conservation efficiency of biodiversity.Then,based on the main contents and conclusions of qualitative analysis,the paper constructs the PSR biodiversity evaluation index system.According to the principle of index selection and the characteristics of the study area,it determines the pressure layer,state layer and response layer,and using the method of analytic hierarchy process(AHP)to determine the weight of each level index,and finally the standardized data are putted into the biodiversity evaluation function,and then it evaluates the biological diversity of the Dafeng National Nature Reserve.Finally,the paper puts forward the protection of biodiversity countermeasures through the combination of qualitative analysis and empirical analysis.It is expected that this study will be helpful to the development of biodiversity conservation policy,and how to further study the relationship between terrestrial wildlife protection and biodiversity from other perspectives,how to further improve the biodiversity evaluation index system and method,and how to build the evaluation index system and other issues for other types of habitat.
