摘要:
基于广西崇左市2001年和2010年两期遥感影像，在遥感、地理信息技术和统计分析工具支持下，应用分形理论对2001—2010年10 a间该地区土地利用类型形态复杂度与结构稳定度的时空格局进行实证研究。结果表明：（1）崇左市边境4县（市）各土地利用类型的分布都具有分形结构，2001年和2010年各地类斑块总体上形状比较规则，结构相对稳定；（2）10 a间各地类的分形维数逐步增大并向临界值1.5逼近，稳定性指数则不断减小并接近于0，呈现出高复杂性和低稳定性的分形演变趋势；（3）大新县和龙州县的水域、凭祥市和宁明县的林园地的复杂性升高而稳定性下降趋势最为明显，大新县和龙州县的未利用地、凭祥市和宁明县的草地变化幅度最小；（4）崇左市今后发展应加强土地利用的规划引导，采取有效措施来适当控制土地类型整体分形维数的增加，维持土地利用结构的稳定性。
Abstract:
Based on Landsat TM images of Chongzuo City, Guangxi in 2001 and 2010, fractal theory was applied to study the spatiotemporal pattern of the morphological complexity and structural stability of land use types in this area during the past 10 years under the support of remote sensing, geographic information techniques and statistical analysis tools. The results showed that: (1) the distribution of all land use types in 4 border counties or cities of Chongzuo City had fractal characteristics, on the whole, the shapes of each land use patch were regular, and the structure was stable in 2001 and 2010; (2)the fractal dimensions of each land use type had been gradually rising and approaching the critical value of 1.5, while the stability indexes continued to decrease towards 0, which led to the land use types to present the fractal evolution trend of high complexity and low stability; (3) the water of Daxin County and Longzhou County and the woodland and garden plot of Pingxiang City and Ningming County had the most obvious tendency of rising complexity and declining stability, on the contrary, the unused land of Daxin County and Longzhou County and the grassland of Pingxiang City and Ningming County changed the least; (4) in the future, Chongzuo City should strengthen the guidance for land use planning, and take effective measures to control increases in fractal dimension and maintain the stability of land use structure.
