基于Stata研究川中紫色土区小流域土地利用变化特征分析
|
摘要
为了定量化研究土地利用变化特征,论文以川中小流域为研究对象,2004年第5期小流域竣工验收报告为基础数据,利用stata13.0软件,以小流域不同利用类型土地,生态环境治理后农地面积、林地面积、草地荒地及其他用地面积建立多元回归方程,分析不同利用类型土地前后的变化特征。结果表明:1)研究时段内不同利用类型土地变化的差异较大。耕地减少至41%,变化较为强烈;变化最为显著的是林地面积增长至48%,反超了耕地占土地总面积的比例;草地、荒地和其他用地降至12%,其变化也是稍有显著地。按土地利用变化程度的大小排序应为:林地>耕地>草地、荒地和其他用地。2)政策方向、经济收入等因素是影响土地利用变化的主要驱动力。
In order to study the characteristics of land use change based on the quantitative and Sichuan Basin as the researchobject,small watershed in 2004 fifth the acceptance report based on the number of data,using stata13.0 software,taking the smallwatershed of different land use types,ecological environment governance area of farmland,forest land area,and other land waste-land area,the multiple regression equations are extablished. The variation characteristics of different types of land use is analyzed.The results show that before and after:1)the study period of different types of land use difference changes greatly. The cultivatedland decreased to 41%,change is strong. The most significant changes of the area of forest land is increased to 48%,ahead of thecultivated land accounts for the proportion of the total land area;grassland,land and other land use fell to 12%,its change is slight-ly significant according to the change of land use. The degree of sorting should be:farmland > woodland> grassland,wasteland andother uses. 2)the policy,economic income and other factors are the main driving forces affecting land use change.
