Study On Optimization Of Land Use Structure In Huyi District Based On Carbon Emissions

Land use patterns are an important factor affecting the carbon balance of regional ecosystem.It is of great significance to explore the low-carbon land use development structure and construct a low-carbon national spatial development pattern for reducing carbon emissions from land use,regional sustainable development and maintaining ecosystem balance.In view of this,this article takes Huyi District as an example to analyze the temporal and spatial evolution characteristics and driving mechanisms of land use,as well as the carbon emissions of land use.With the goal of reducing carbon emissions as the optimization goal,the land use structure is reasonably configured,and optimization measures and suggestions are proposed to provide reference for the formulation of regional land spatial utilization policies.The research results indicate that:(1)There were significant differences in the changes in land use types during the study period.The area of forest land,construction land,water,and other land has increased,while the area of farmland,garden,and grassland has decreased,mainly due to changes in farmland,construction land,and forest land.The intensity of land development and utilization has increased,with Ganting Street having the highest intensity and Shijing Street having the lowest intensity.The main mode of land use change is the conversion of farmland to construction land,while the transfer of other land types is relatively weak.(2)During the research period,the carbon emissions from land use increased by132131.59 tons,and the increase in indirect carbon emissions from the development and utilization of construction land is the main reason for this result.With the growth of the social economy,the risk of carbon emissions from land use in the research area has increased,mainly in Level I areas,but the area is on a decreasing trend,while other higher level risk areas are on an increasing trend.(3)Through quantity and spatial accuracy tests,it was found that using the PLUS model to simulate the land use situation in the study area is feasible and can achieve good simulation results.According to the original land use policies and historical change patterns,it is simulated that the expansion trend of construction land is obvious in 2030,and the occupied land is mainly farmland;The area of forest land and grassland increased,while the area of other land types showed a decreasing trend.At the same time,the carbon emissions from land use are still increasing,which to some extent threatens the security of regional ecosystems.(4)After optimizing the quantity structure of land use,the land use structure tends to be reasonable,which is more conducive to the low-carbon development of national land space.After optimizing the spatial layout,the production and construction activities in the southern part of the research area have been curbed,which is conducive to the protection and restoration of the ecological environment in the Qinling Mountains;Strengthening the connectivity of water is conducive to the construction of ecological corridors and the maintenance of regional ecological security patterns;The expansion trend of construction land has been effectively controlled,which is conducive to improving the efficiency of conservation and intensive utilization on the basis of carbon reduction,while reducing the degree of interference to farmland and regional ecosystems;The ecological land patches and coverage area in the central and northern regions have increased,and the "green expansion" effect is significant,which is conducive to ensuring the ecological security of the entire region.
