摘要:
[目的] 探究中越边境带广西段土地利用变化特征及其驱动力,为优化该地区土地利用结构提供依据。[方法] 采用土地利用动态度、土地利用转移矩阵和莫兰指数分析中越边境带广西段1980-2018年土地利用变化时空特征,并构建多元线性回归模型探究其驱动力。[结果] ①1980-2000年和2000-2018年两个时段中越边境带广西段的综合土地利用动态度分别为0.43%,4.50%。2000年以前土地利用变化速度较为平缓,之后土地利用变化速度加快。②各土地利用类型之间均发生相互转移行为。1980-2000年、2000-2018年参与土地转移面积分别为4 775.92,46 730.06 hm2;建设用地和水域面积增加,耕地、林地、草地和未利用地面积减少,其中建设用地新增面积9 134.47 hm2,90%来源于耕地、林地、草地和未利用地减少的面积。③中越边境带广西段各土地利用类型存在显著正向空间自相关关系,表现出较强的空间集聚效应,但局部空间集聚效应发生变化和迁移。④边境贸易是加速该地区土地利用变化的主要因素之一,与人口、经济和政策等因素共同影响中越边境带广西段土地利用变化。[结论] 中越边境带广西段土地利用变化存在明显的空间分异特征,随着边境开放开发速度加快,土地利用格局演变加速。

Abstract:
[Objective] The characteristics and driving force of land use change in the border zone between Guangxi Zhuang Autonomous Region of China and Vietnam were explored to provide a basis for the optimization of land structure utilization.[Methods] The spatial-temporal characteristics of land use change in the China-Vietnam border zone of Guangxi Zhuang Autonomous Region from 1980 to 2018 were analyzed using the land use dynamic index, land use change matrix, and Moran index. A multiple linear regression model was built to explore the driving force.[Results] ① The comprehensive land use dynamic degrees of the China-Vietnam border zone of Guangxi Zhuang Autonomous Region during the periods of 1980-2000, and 2000-2018 were 0.43% and 4.50%, respectively. Before 2000, the land use change was relatively mild, and the pace accelerated thereafter. ② Land-use-type transfer occurred for all the lands. In the stages of 1980-2000 and 2000-2018, the overall transferred land acreages were 4 775.92 and 46 730.06 hm2, respectively. In addition, the construction land and water area expanded, and the arable land, woodland, grassland, and unused land decreased. Moreover, 9 134.47 hm2 was added to the construction land, and 90% can be traced back to arable land, woodland, grassland, and unused land. ③ The types of land in the China-Vietnam border zone of Guangxi Zhuang Autonomous Region showed an obvious positive spatial autocorrelation and a relatively high space agglomeration effect, and changes and transfers occurred in the regional space due to agglomeration effect. ④ A principal factor contributing to the land utilization change in the area was border trade, which was accompanied by population, economy, policy, and other factors affecting the land use change in the China-Vietnam border zone of the Guangxi Zhuang Autonomous Region.[Conclusion] The land use change in the China-Vietnam border zone of the Guangxi Zhuang Autonomous Region has obvious spatial differentiation characteristics. With the acceleration of border opening and development, the evolution of land use patterns accelerated.
