| 摘 要： | 以北方农牧交错带典型生态示范村尧勒甸子村为例,应用参与式农村评估法(PRA)并结合GPS与野外测量,恢复了该村1949年后50 a来的土地利用历史过程与格局,利用GIS分析其1950-1999年的土地利用变化特点.运用因子分析和逐步回归分析方法揭示了人类活动因素对土地利用变化的作用.结果发现1985年以前耕地面积扩大,草地面积减小,沙地面积迅猛持续增加;1985年以后土地利用变化向相反的方向发展,土地利用结构趋向合理.

| Abstract: | With Village Yaoledianzi,an ecological demonstration village in the ecotone between agriculture and animal husbandry in north China as an example,the land use history from 1950 to 1999 has been reconstructed on the basis of PRA,GPS and field measurement.The characteristics of the changes in land use has also been analyzed by spatial overlay in GIS.Factor analysis and stepwise regression are used to probe into effects of human activities on land use.It is found that before 1985 cultivated land and sand land expanded both at the cost of grassland;land use turned in reverse and to be more logical after 1985. |
