| With the rapid development of China’s economy,people’s land use is increasing,accelerating the depletion of land resources,and the ecosystem has borne great pressure,resulting in a continuous decline in the benefits of ecosystem services.As a link between natural ecosystems and human well-being,the achievement of sustainable ecosystem services in the region plays a crucial role.The decline of ecosystem service capacity will lead to more severe problems such as ecological security and sustainable use of resources in China,and the stability of the ecosystem in Northeast China,as an important ecological barrier area in China,involves China’s ecological security.Land-use change alters ecosystem patterns and processes,which in turn affects the ability to provide ecosystem goods and services.At present,it is urgent to study the impact of land use change on the spatial and temporal situation of ecosystem services in Northeast China,so as to make a scientific and objective assessment of the quality of ecological environment services in Northeast China,for the reference and reference of government departments,and refer to the assessment results to carry out targeted governance of ecosystem issues and effectively promote the management of ecosystem services in Northeast China.Taking Northeast China as the research area,this paper quantifies the spatiotemporal changes of land use in the whole region and various landscape areas in Northeast China in 2000,2010 and 2020,and uses two types of models of land use dynamics and land transfer matrix to analyze land use changes in Northeast China from2000 to 2020.Based on the model simulation results,the temporal and spatial evolution of ecosystem services in Northeast China was analyzed,and finally the impact of land use change on ecosystem services in Northeast China was comprehensively discussed.Based on the results of the discussion,the relevant countermeasures and suggestions conducive to land use and ecological protection in Northeast China were put forward,so as to realize the sustainable development of ecosystem services in Northeast China. |
