| Forest plant species diversity as the main component of forest biodiversity,there is a huge economic,ecological and humanistic value,have important meaning to sustainable development of society,but in the process of agricultural industrialization in China since the founding of the people for the understanding of the value of forest plant species diversity protection inadequate,causing forest plant species diversity in our country,therefore,to study the value of forest plant species diversity and evaluate the status quo of the species diversity of forest plants in China is not only beneficial to promote the concept of forest biodiversity mainstream,more can promote sustainable development of forest.This paper adopts the method of qualitative and quantitative research.The first chapter explains the research background,purpose and significance,extensively collects and reads relevant literature at home and abroad,sorts out the existing research conclusions and summarizes the shortcomings of domestic existing research,clarifies the research direction of this paper,and expounds the technical route and research ideas of this paper.The second chapter mainly introduces the related concepts and basic theory method,this paper expounds the biodiversity,the meaning of forest plant species diversity and productivity,then the sustainable development theory,biodiversity and ecosystem services has carried on the brief introduction of the economics theory,finally,the theory of causal path analysis and forest plant species diversity evaluation theory,this paper expounds in detail the research methods such as theory and method support for follow-up study provided;The third chapter makes a comprehensive analysis of the advantages,disadvantages,opportunities and challenges of forest plant species diversity in China by using the situation analysis method.The fourth chapter analyzes the value mechanism of forest plant species diversity to sustainable development from three aspects: ecology,economy and humanity.The fifth chapter according to the geographical location,forest distribution and characteristics of the economic and social development,will be divided into five major areas in our country,build PSR evaluation index system,using the method of AHP analytic hierarchy process(AHP)and entropy weight method,determining the weight in the form of line charts for 10 years from 2008 to2017,China’s forest plant species diversity in the visual display and analysis and evaluation;Finally,some Suggestions for protecting the diversity of forest plant species were put forward.The results of qualitative analysis show that forest plant species diversity,as the main component of biodiversity,can improve forest productivity through niche complementary effect and selection effect of biodiversity effect,and then strengthenforest ecosystem service function,thus reflecting its ecological value for sustainable development.Forest resources with the diversity of forest plant species as the carrier can provide a large number of food materials,industrial raw materials and tourism and leisure resources for the development of human society,and realize the transformation from the nature of natural resources to the economic value.It highlights its humanistic value in promoting artistic creation,national health quality,cultural inheritance and landscape diversity,and promotes sustainable development in ecology,economy and humanity.Empirical study results show that although the forest plant species diversity in China in recent 10 years overall declining,the pressure response index shows the sharp rise in small scale fluctuation,but the state layer has no obvious improvement,forest plant species diversity in the small scale fluctuation basic stand(between 0.2 to 0.5),mainly because of low success rate in the treatment of forest pest,fires occur frequently and most parts of the natural forests are destroyed in forest quality is low,at the same time also shows that the forest plant species diversity of scientific research in China and the lack of awareness of important value.It is suggested to carry out conservation work from the following aspects: optimizing industrial structure and fostering new drivers of economic growth;To improve laws and regulations and strengthen law enforcement and supervision;Attaching importance to scientific research and promoting innovation of protection means;Protect natural forests and improve forest quality accurately;To promote the mainstreaming of forest plant species diversity. |
