基于广西陆地边境2001—2012年土地利用变更数据，运用土地利用动态度、土地利用程度、土地利用结构信息熵等指数系统分析土地利用变化特征，并采用生态系统服务价值评价方法，分析土地利用变化引起的生态效应。结果表明：（1）广西陆地边境土地利用呈现“林地—耕地—未利用地”主导的地域结构特征，近11年来土地利用的变化速度不断加快，反映了人类活动对土地利用变化的影响强度逐渐增大。（2）土地利用结构信息熵和均衡度呈现总体波动下降态势，优势度则逐年上升，说明土地利用系统向着相对有序方向发展，土地利用结构的动态演变过程，主要表现为农业内部结构调整、未利用地的开发及建设用地的增加，同时预示着边境经济发展形式的调整优化过程。（3）土地利用变化产生了较好的生态效应，生态系统结构不断优化，土地利用生态服务价值年均增长11．7％，土地利用整体生态效益持续提高，说明边境社会经济的发展并未以生态环境的恶化为代价，其发展是可持续的。

Based on detailed survey data of land use from 2001 to 2012 ,using the dynamic degree mode ,change of land use degree mode and information entropy to analyze the characteristics of land use change ,and using ecosystem services evaluation methods to analyze ecological effects caused by changes in land use patterns ,results show that :(1) Regional structure of land use in Guangxi border is forest land ,cultivated land ,unused land .T he speed of the change of land use has been accelerating in the last 11 years ,it can reflect that the intensity of the influence of human activity on the land use change is gradually increasing .(2)The information entropy and equilibrium degree gradually decrease in trend of fluctuations ,but the dominance degree is rising year by year ,which reflects the land use system is developing tow ards a relatively orderly state ,the dynamic evolution of land use structure is mainly expressed as the internal restructuring of agriculture ,the exploitation of unused land and the increase in the construction land .Meanwhile ,it can also indicate the optimization process of border e‐conomic development form .(3)The change of land use produces a better ecological effect ,and the structure of the ecosystems is continuously optimized ,the value of land use ecological services increa‐ses by 1 1.7% annually ,the overall eco‐efficiency of land use continues to improve ,the development of the social economy in the border is not at the price of the ecological environment ,and its development is sustainable .
