Study On Ecosystem Service Value Based On Land Use In The Northeast Tiger And Leopard National Park

With the establishment of the national park system,attention has been paid to the protection of the ecological environment quality of national parks.The Northeast Tiger and Leopard National Park(The following article replaces the Northeast Tiger and Leopard National Park with NTLNP)was established to protect endangered wildlife and the integrity of the natural environment,among them,there is a close relationship between land use and ecosystem service value(The following article replaces ecosystem service value with ESV).Therefore,improving the ecological environment quality in the region is not only the demand of ecological civilization construction in China,but also the only way for contemporary human beings to build a better home.In this study,the land use data of 1995a,2000a,2005a,2010a,2015a,and 2018a were analyzed using GIS technology in NTLNP.The spatiotemporal change rules of regional land use in the study period were quantitatively analyzed from the aspects of land use change amplitude,dynamic attitude and transfer situation.From the point of view of spatiotemporal change,based on the revised value equivalent,the regional value quantity change rule was analyzed.Combined with the previous research results,the relationship between the two factors was analyzed from various aspects,such as the degree of coordination of the sensitivity coefficient of variation contribution rate.This article aimed to provide some data basis for future NTLNP research.The main conclusions of the study were as follows:First,the land use change in the study area was significant.Take 2018 as the end of the time,the study area average of various land types from high to low order as:forest(29)cultivated land(29)grassland(29)construction land(29)unused land(29)waters.It is mainly forest type,accounting for more than 90%of the total area,suitable for forest ecotourism,water area is the smallest,the average percentage of 0.17%,should be strengthened protection.Second,ESV decreased slowly from 1995 to 2018.The value in the six research years was36.690×10~8yuan,36.551×10~8yuan,36.525×10~8yuan,36.448×10~8yuan,36.448×10~8yuan,36.319×10~8yuan,respectively.From the perspective of each land use type,the ESV ranking was:forest>cultivated land>grassland>waters(29)unused land>construction land,forest contributes the most.From the perspective of the first-level ESV type,the ESV order was:adjustment service>support service>supplying services>cultural services.From the perspective of each study area,the order of ESV was:Wangqing>Hunchun>Dongning>Ningan>Muling.Third,the coordination degree between land use and ESV is low.Take 2018 as the end of the time,the degree of coordination was mainly moderate conflict and low conflict,and gradually changed from moderate conflict to low conflict.From the aspects of land use type change,the main reason is that the forest land is transformed into other land use-type,and the area decreases,leading to the decrease of the overall ESV.From the perspective of the contribution rate of variation,the changes of forest land and total ESV showed the same direction,while the decrease of grassland,water area,unused land and total ESV showed negative effect.From the perspective of sensitivity,the sensitivity coefficients of ecosystem service value of land use in the six periods were all less than 1,the order was:forest land>cultivated land>grassland>waters>unused land.Based on the above results,in order to improve the ESV of the NTLNP,the maintenance of forest land should be strengthened,the water area should be expand,the area of grassland and cultivated land should be reasonably control,and the area of construction land and unused land should be reduce.In terms of improving the functions of national parks.we should give full play to the function of ecological education,follow the principle of regional division,and actively promote the transformation of communities.In the future,this paper can be used as a basis to continue to expand the research on the root causes of land use change,national park management,community residents’satisfaction and other aspects,and constantly enrich the regional research content.
