The Assessment And Value Realization Of Ecosystem Service Value Of Qinling Mountains Of Shaanxi Province

As the central mountain range in my country,the Qinling Mountains are the north-south dividing line in China’s geographic space and a barrier for the country’s important ecological security.With the continuous economic development of the Qinling region of Shaanxi Province,it is also faced with the huge challenges of sustainable green industry development and improving the economic income of people in the mountainous areas.Based on a number of data such as meteorology,land use,vegetation coverage,social economy,and Qinling’s spatial management and control,this paper implements the concept of “lucid waters and lush mountains are invaluable assets ”,and explores the temporal and spatial evolution of the Qinling ecosystem service value from 2010 to 2020.Based on the comparative analysis of time and space with social and economic data,based on the analysis results,combined with the relevant plans and policies of Shaanxi provincial governments at all levels for the Qinling area,the green development and environmental protection strategies and suggestions for the Qinling Shaanxi province are put forward.From 2010 to 2020,grassland and forest ecosystems in the Qinling Mountains and Shaanxi Province were the most widely distributed,accounting for 65% of the total area;the area of each ecosystem type has been maintained as grassland>forest>farmland>shrub>urban>wetland>bare land.Structural characteristics: On the whole in 10 years,the area of farmland ecosystems decreased greatly,the shrub and grassland ecosystems decreased slightly,the forest ecosystems changed the most and increased in area,and the wetlands,urban and bare land ecosystems all increased slightly.In 2010,2015 and 2020,the results of the Qinling Ecosystem GDP were 435.337 billion yuan,480.9439 billion yuan and 589.334 billion yuan respectively.In the past ten years,the GDP of the ecosystem has increased slightly,mainly because the value of the supply products and cultural services has continued to increase and the growth rate has been relatively fast,while the growth rate of adjustment services has been slow.The order of the GDP of the ecosystems of the cities will remain in the following ten years: Shangluo >Hanzhong > Ankang > Baoji > Xi’an > Weinan.In the past ten years,37 districts and counties have experienced positive growth in the total value of ecosystem production,while 37 districts and counties experienced negative growth.2(Lintong District,Xi’an City,Huayin City,Weinan City).Based on the results of the temporal and spatial evolution of the GDP of the ecosystem and local economic data,combined with the existing plans,relevant countermeasures and suggestions for the green development and environmental protection of the Qinling Mountains are put forward.Predict the lowest index of the growth rate difference between GEP density and GDP density in each district and county in Qinling-Shaanxi Province from 2020 to 2030,and formulate the priority index of ecological compensation in each district and county in Qinling-Shaanxi Province.
