| 摘要: |
| 选择典型高原生态脆弱区中的林芝市为研究对象。以2005、2010和2015年3期土地利用数据为基础,同时结合研究区社会经济统计数据,采用GIS技术及SPSS分析功能,研究林芝市土地利用的空间动态变化特征,分析影响林芝市LUCC的驱动因子。研究结果表明：2005～2015年间建设用地与林地面积变化量最大,分别增加了16.4 km2和减少了17.1km2；草地和林地持续减少,而建设用地和水域持续增加；在空间上草地面积主要转移方向为建设用地和水域,林地的转移方向主要为建设用地和草地。总体来说10年间林芝市的土地覆被宏观生态状况处于逐步恶化的趋势；林芝市农牧人口的增长、农牧业及社会经济发展是林芝市土地利用变化的主要驱动力。 |

| Abstract: |
| Taking Nyingchi in the typical plateau ecologically fragile area as the study object. Based on the land use data of 2005, 2010 and 2015, combined with the socio-economic statistics of the study area, using GIS technology and SPSS analysis, the spatial dynamic characteristics of land use in Nyingchi were studied, and the driving factor of LUCC in Nyingchi was analyzed.The results show that the area of construction land and forest land changed the most from 2005 to 2015, increasing by 16.4 km<sup>2</sup> and decreasing by 17.1km<sup>2</sup> respectively; the grassland and forest land continued to decrease, while the construction land and water area continued to increase; the main transfer direction of grassland area in space is construction land and waters, the transfer direction of forest land is mainly construction land and grassland. In general, the macro-ecological status of land cover in Nyingchi is gradually deteriorating in the past 10 years; the growth of population engaged in agriculture and animal husbandry, development in agriculture and animal husbandry and social and economic improvements are the main driving forces for land use change in Nyingchi. |
