| 摘 要： | 天祝县土地利用/土地覆盖变化对石羊河流域的环境变化影响很大,研究其变化可为天祝县及石羊河流域可持续发展提供决策依据。基于3S技术,探测了20世纪末天祝县土地利用/土地覆盖变化情况,利用土地利用变化动态度和土地利用转移矩阵分析了变化的特点。主要结果如下:耕地增加较快,主要增长方式是毁林草地和开荒;未利用地转变为林草地在空间分布上很有规律,80%以上分布于4000 m左右的高山顶部。

| Abstract: | The environmental changes of Shiyang River watershed have been greatly affected by land-use and land-cover change(LUCC) in Tianzhu County.Basing on remote sensing,geographic information system and global positioning system(3S),LUCC in Tianzhu county in the late 20cn were studied,and the feature of changes by land use,dynamic change degree and land use conversion matrix were analyzed.The results show that the important feature of LUCC in Tianzhu County in the late 20th century.Farmland had risen rapidly by destroying wood-grass as well as reclamation;the phenomenon of unused land changing into wood-grass land was unusual.From the view of spatial distribution,81.03% of this change happened on top of the mountains of 4 000 meters high above sea level. |
