吉林省自然资源综合区划、动态变化及其原因分析
Comprehensive regionalization,dynamic changes and cause analysis of natural resources in Jilin Province
摘要
Abstract
[Objective]Conducting comprehensive zoning analysis of natural resources can promote the"two unifications"management of natural resources,and provide scientific solutions for natural resource asset management,national spatial planning and use control,ecological protection and restoration,and other earth system issues.[Methods]Taking Jilin Province as an example,based on the framework of basic surveying and mapping results,digital elevation models,and high-resolution remote sensing images,a comprehensive zoning index system is constructed from multiple dimensions such as terrain and geomorphology,temperature and precipitation,vegetation coverage,water production modulus,and resource proportion to conduct natural resource comprehensive zoning and analyze its dynamic change characteristics.[Results](1)The region is divided into 19 natural resource sub regions,among which the southern mountainous humid forest mining sub region,the eastern mountainous humid forest mining sub region,and the northern high plain semi humid cultivated land sub region have the largest areas,accounting for 15.26%,12.79%,and 10.35%,respectively.(2)From 2010 to 2020,the succession of natural resources manifested as the mutual transformation between cultivated land,forests,and grasslands.The overall trend of dominant resource changes in the study area was a decrease in forest resources and an increase in cultivated land resources,specifically manifested as the transformation of forests into cultivated land and grasslands into cultivated land.The mutual transformation between forest land and cultivated land was mainly located in the semi humid cultivated land sub area of the northwest inclined plain and the humid forest cultivated land sub area of the eastern basin.The mutual transformation between grassland and cultivated land was mainly located in the humid cultivated land sub area of the central plateau.The average proportion of cultivated land in the western cultivated land sub area increased from 56.6%to 59.2%,and the average proportion of forest land in the eastern forest cultivated sub area decreased from 66.5%to 54.9%.[Conclusion]Jilin Province's natural resources are dominated by forest land and arable land.Influenced by national policies,climate conditions,and socio-economic factors,the advantages of arable land resources in the western and central regions have relatively increased,while the advantages of forest land,grassland,and water resources in the western region have decreased.关键词
