基于Stata研究川中紫色土区小流域土地利用变化特征分析
Study on the Characteristics of Land Using Change in Small Watershed of Purple Soil Area in Sichuan Province Based on Stata
摘要
Abstract
In order to study the characteristics of land use change based on the quantitative and Sichuan Basin as the research object,small watershed in 2004 fifth the acceptance report based on the number of data,using stata13.0 software,taking the small watershed 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 cultivated land decreased to 41%,change is strong. The most significant changes of the area of forest land is increased to 48%,ahead of the cultivated 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 and other uses. 2)the policy,economic income and other factors are the main driving forces affecting land use change.关键词
