Evaluation Of Ecological Assets In National Nature Reserve Based On Ecosystem Services

Affected by factors such as geographical environment and climate,China's ecologically fragile areas account for about 60% of the country's land area.With the acceleration of China's industrialization and urbanization,the disorderly development and excessive development of some cities located in ecologically fragile areas have led to the dwindling biological resources and the serious damage to the ecological environment.People have always been ignoring ecological assets.The lack of ecological assets in the regional management system has also caused problems such as low resource utilization efficiency and uneven regional development.The establishment of national-level nature reserves is an important measure to maintain biodiversity and optimize the regional ecological environment.This article takes the Jiulianshan National Nature Reserve in Longnan County,Ganzhou City,Jiangxi Province as an example.On the one hand,the ecological asset value of the Jiulianshan National Nature Reserve is evaluated,which is helpful to help government departments and the public better Understand the ecological value of nature reserves;on the other hand,based on the actual situation of Jiulianshan National Nature Reserve,this article establishes a more comprehensive ecological asset assessment system to serve the ecosystem value of Jiulianshan National Nature Reserve The data of time and space changes provide data.This article uses Jiangxi Jiulianshan National Nature Reserve as the research area.Based on the existing literature research,and combined with the survey results,data collection,and other relevant parameters,the market value method,shadow engineering method,and equivalent factor method are used.Method,from the perspectives of supply,regulation,support,and cultural services,respectively,to evaluate its products,forest resources,organic matter production,gas regulation,water conservation,purification of the environment,soil conservation,biodiversity,recreation,and scientific research10 Value of ecosystem services.The conclusions of the study are as follows:(1)The total value of ecosystem services in Jiulianshan National Nature Reserve in 2017 was 1.394 billion yuan,which shows that nature reserves can not only provide people with direct economic benefits,but also have a potential ecological value far greater than society.Economic value;(2)Of the ecosystem service value,the value of supply services,adjustment services,support services,and cultural services were 18,519,682 yuan,5,86,696,600 yuan,6,17,855,500 yuan,and 2,588,800 yuan,respectively.Support services and adjustment services accounted for 86.53% of the total.Specifically,climate regulation,soil conservation,and biodiversity value accounted for 75.87% of the total value,which are the main service functions of the ecosystem in the Jiulian Mountain Reserve.(3)From the perspective of ecosystem types,the value of different types of ecosystems is ranked as broad-leaved forest(85.95215 million yuan)> coniferous forest(277.6614 million yuan)> coniferous and broad-leaved mixed forest(85.926 million yuan)> bamboo forest(59.64 million yuan)>Shrub forest(59.519 million yuan)>Agricultural land(277.6 million yuan)> Water area(20.916 million yuan).Among them,the broad-leaved forest in Jiulianshan National Nature Reserve has the highest value,and has contributed 61.65% of the value with a land area of 55.37%.By assessing the value of different types of ecosystems,it is beneficial to further enhance the ecological assets of nature reserves,thereby better achieving sustainable environmental development.Finally,through the evaluation of the ecosystem service function of jiulianshan national nature reserve,this shows that the Jiulianshan Nature Reserve plays an important role in maintaining and enhancing local social and economic development.
