| 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. |
