摘要
利用监督分类和非监督分类相结合的分层提取分类方法对南川市2000年遥感影像进行解译。然后结合1995年土地利用现状数据,运用分类结果比较法求得研究区土地利用/覆盖变化转移矩阵,据此对南川市1995─2000年土地利用/覆盖变化进行研究。结果表明:南川市1995─2000年耕地、居民点及工矿用地面积增加,林地、草地面积相对减少。这一土地利用/覆盖变化的驱动力主要是南川市城市化与经济发展速度的加快、产业结构的调整以及人口增长与消费方式的转变。
The image of Nanchuan in 2000 was interpreted using a multi-extracting method combining supervised classification with non-supervised classification. Then based on the land use data in 1995, a land use change matrix for 1995-2000 was worked out using a classification comparison method. The results showed that the area of land used for agriculture, residential settlements and industry and mining was increasing, however the area of woodlands, and grasslands was decreasing. The driving forces of the change were mainly acceleration of urbanization and economy development, adjustment of industrial structure, rapid growth of population and change in patterns of consumption.
