Study On Ecological Management Of Forest Landresources In Liaoning Province Based On GEP Assessment

As the largest ecosystem on land,woodland is of great significance to the maintenance and development of the ecological environment.In the entire terrestrial ecological environment,forest land plays the role of a mainstay,which has both material production capacity and its enormous ecological service function.However,at present,China's forest land resources still face many problems,so that the ecological value of forest land resources cannot be fully utilized.Based on this,this paper firstly extensively reads and studies the researches and related literature of predecessors at home and abroad,by grasping the connotation of the forest resource ecosystem production value(GEP)system and the indicators it contains,taking Liaoning Province as the study area,select the forestland resource data from 2012 to 2016,based on the total ecosystem production(GEP),the ecological supply value,ecological adjustment value,ecological support value and ecological cultural value of forest land resources in Liaoning Province were evaluated.Based on the data of forest land resources in Liaoning Province,this paper calculates the ecological service value of forest land resources in the study area,and uses the spatial statistical method to analyze the spatial and temporal differences of the ecological value of forest land resources in Liaoning Province.The service value of forest ecosystem was estimated by selecting "forest product supply,environmental purification,water conservation,biodiversity maintenance,carbon fixation and forest recreation" as indicators.Referring to the previous research results,the evaluation system of forest ecological service value was constructed,and the corresponding evaluation results were obtained.Through the analysis of the research results,the problems of forest land resources ecosystem in Liaoning Province include: reduction of ecological supply value of forest land resources,the value of ecological regulation of forest land resources increased slowly,the value of ecological support of forest land resources increased weakly,and the value of ecological culture of forest land resources decreased.The reasons for these problems are unrestrained expropriation and occupation of forest land,scattered overall area of forest land resources,less investment in forest land resources production,one-sided pursuit of economic interests.Therefore,it is necessary to improve the protection of forest land resources,scientifically plan the area of forest land,increase the investment of forest resources funds,and increase the propaganda of forest land resources protection.By evaluating the ecological value of forest land resources,we can scientifically understand the value of forest land,so as to maximize the ecological benefits of forest land resources.
