Response of LUCC Carbon Emissions to Landscape Pattern Change in Lu'an City based on Frastate
In the process of achieving the"double carbon"goal,it provides scientific decision-making support for Lu'an city to formulate regional low-carbon development strategies,optimize land use structure and improve land management efficiency.Based on the land use data of Lu'an city in the fifth period from 2000 to 2020,the landscape pattern index was calculated by using Frastate4.2 software,the carbon emission coefficient method was used to quantitatively evaluate the carbon source and carbon sink of the land,and the gray correlation model was used to quantitatively analyze the correlation degree between the two.The results showed that:1)From 2000 to 2020,the degree of landscape fragmentation in Lu'an city increased significantly,and the distance between patches was scattered,which led to the development of landscape system to more complex levels,and at the same time,the landscape diversity also changed from singularity to complexity.2)During the same period,the carbon sources and carbon sinks in Lu'an city showed an increasing trend,but the growth of carbon sources made Lu'an city a net carbon emission area,and the total carbon emissions showed an increasing trend.3)There was a significant correlation between the growth of carbon emissions in Lu'an city and the fragmentation of landscape pattern,the enhancement of distribution complexity,the increase of inter-patch dispersion,and the reduction of the maximum patch area.Landscape pattern change is a key driving force affecting carbon emissions in Lu'an city.Therefore,when formulating regional low-carbon development strategies,it is necessary to comprehensively consider the dynamic changes of landscape pattern,and effectively reduce carbon emissions and promote regional sustainable development by rationally adjusting land use patterns and optimizing land use measures.
