| 摘 要： | 分析了1997～2008年拉萨市农业人口、非农业人口、人口密度状况对土地利用变化的意义,探讨了人口非农化与耕地变化之间的关系。结果表明,人口非农化趋势较为明显,耕地面积持续减少;拉萨人口非农化与耕地协调系数均小于1,拉萨市目前的人口非农化对耕地的影响并不严重。

| Abstract: | This paper analyzed the significance of the agricultural population, non-agricultural population, population density in the process of non-agricultural population from 1997 to 2008 in Lhasa City. It discussed the relationship between non-agricultural population and the variation of cultivated land. Results showed, the trend of non-agricultural population was significant while cultivated land decreased gradually. The coordination coefficient between non-agricultural population and the variation of cultivated land was less than 1, which indicated that the impact was not serious at present. |
