Research On The Service Value Of Land Ecosystem In Heilongjiang Province Based On LUC

Since the new era,the economic and social development of Heilongjiang Province has entered a new stage.With the population growth in the province,the ecological environment problems people are facing are becoming increasingly prominent.Basically,it is the weakening and lack of land ecosystem services.Economic benefits and ecological environment are both opposite and interdependent.In the process of sustainable economic and social development,balancing the relationship between economic benefits and ecological environment is an urgent problem to be solved.The analysis of the impact mechanism of the value of land ecosystem services under the change of land use has become a hot issue in current political,economic and social research.From the perspective of land use,this paper selects Heilongjiang Province as the research area,takes 2005-2020 as the research period,based on the spatial remote sensing image data of Heilongjiang Province in 2005,2010,2015 and 2020,and refers to the evaluation model related to land use,to deeply analyze the characteristics of land use change in Heilongjiang Province.At the same time,the service value of the land ecosystem in Heilongjiang Province was calculated by using the equivalent factor evaluation model of the service value of the land ecosystem in China revised by Xie Gaodi in 2015,and the spatio-temporal distribution characteristics of the service value of the land ecosystem in Heilongjiang Province were systematically and deeply studied,and the service value of the land ecosystem of each service function in Heilongjiang Province was calculated,combined with sensitivity analysis,This paper discusses the mechanism of land use change and its impact on the service value of land ecosystem in Heilongjiang Province,which will provide reference and decision-making basis for the scientific and rational use of land resources in Heilongjiang Province,and lay the foundation for achieving the win-win goal of high-quality economic and social development and ecological environment protection.
