| 摘 要： | 基于遥感和地理信息系统，应用转移矩阵方法和Kappa指数系列对岷江上游的耕地景观变化进行研究分析。研究结果表明1974到2000年间耕地景观数量一直处于增长趋势，且与其它景观类型相互转换频繁，耕地景观大部分由有林地转化。1974到1986年期间，耕地面积增幅最大。Kappa指数系列计算结果表明，虽然耕地景观在1986到2000年间耕地面积增加不明显，但空间位置变化剧烈。

| Abstract: | Based on RS and GIS, the change of farmland landscape with methods transition matrix and Kappa coefficient in the upper reaches of Minjiang River was studied. The results showed that area of farmland landscape kept increasing from 1974 to 2000, and conversion with other landscape types frequently. The farmland landscape mainly converted from the forest landscape. Area of farmland landscape increased dramatically from 1974 to 1986. According to the results of Kappa coefficient, though the area change of farmland was not obvious from 1986 to 2000, but the spatial change was dramatic. |
