林芝市退耕还林时期土地利用变化研究
A Study of Land Use Changes in Linzhi City During the Grain for Green Program Period
摘要
Abstract
To reveal the characteristics of land use changes after the conversion of farmland to forest in Linzhi City,explore the relationship between different driving factors and land use conversion changes,and provide a scientific basis for ecological projects in Xizang,this study was based on the land use change data of Linzhi City in 2000,2010,and 2020,and combined statistical materials for analysis.According to the research results,during the period from 2000 to 2020,the farmland area in Linzhi City showed an increasing trend,with a specific area change of an increase of 72.05 km²,which may be related to the local population growth.In terms of land use,the areas of farmland converted to forest,shrubland,and grassland were 56.30 km²,2.06 km²,and 60.53 km²,respectively.Regarding the dynamic degree of land use,the single dynamic degree of farmland changed from-1.83%to 3.93%.There was a relative tendency in the conversion intensity of farmland to shrubland and grassland.The relative intensity of farmland converted to forest was similar to the values of shrubland and grassland.In terms of the relationship between driving factors and land use,there was a positive correlation between the gross domestic product,the gross product of the primary,secondary,and tertiary industries,and farmland.Economic growth and the implementation of the policy of converting farmland to forest may have influenced the land use changes in Linzhi City.The specific impact of the policy on the land use changes of the regional ecosystem still needs further in-depth verification.关键词
