Evaluation Of Ecosystem Service Function Value In Western Jilin

The ecological environment is the basis for human survival and development,the production and life of human beings cannot be separated from the support and service of the ecosystem.Therefore,the objective understanding and evaluation of the ecosystem,and reasonable quantitative analysis of its service function have great significance for us to achieve sustainable development with the harmonious coexistence of human beings and the ecological environment.Remote sensing technology has great advantages in data acquisition.It can achieve large area synchronous observation,with strong timeliness and comprehensive and comparable data.Therefore,remote sensing technology is widely applied in various research fields.This study is based on the remote sensing technology,GIS analysis method,combine with ecological service environmental ecology analysis methods and means,cover and landscape the change of land use in the study area,analyze the three aspects as well as the function value of ecosystem services,and have finished the reasonable forecast which was based on the Markoff model.Meanwhile,a suitable index model was built to compare the ecosystem services and economic development of two main parts of the research area,Baicheng and Songyuan.The results show that:(1)The dominant land use types in the area is farmland,and affected by human factors,In the type of land use,the area of cultivated land,grassland,construction land,unused land increase,the other three types of land use area reduced,various types of land use landscape area shaped complex broken,reduce the degree of difference.(2)As for the ecosystem service function,ecological service function value of the western region of Jilin is expected to become weakened,the ecosystem service function value in the area in 2025 was only 65 billion 441 million yuan,accounting for about 65.48% of the initial state of the region,if things go onlike this,the healthy development of the economy produce adverse effect.(3)The economic contribution rate of the ecological service economy in Baicheng is lower than that of Songyuan,and the economic development and the utilization of ecological environment resources are at a disadvantage.
