老挝凯山丰威汉市土地资源的空间优化配置

[目的] 通过土地资源的空间优化配置，提高土地利用效率，促进各类产业和基础设施的合理布局，为区域社会经济综合发展提供理论依据。[方法] 将GIS空间分析技术、Logistic回归分析方法与CLUE-S模型相结合，以老挝凯山丰威汉市为研究区域，开展土地资源空间优化配置研究。在空间适宜性和数量结构的约束下，以用地需求、限制因素、转换规则和空间特征为基础进行模型运算，对凯山丰威汉市土地资源进行空间优化配置。[结果] 城市建设用地和水田在原有基础上向适宜区域扩张，分布较为稀疏的林业用地因得到开发利用而相应减少，其他用地类型在数量上和空间上的变化均不明显。[结论] 城镇化建设和农业发展能够为凯山丰威汉市的经济发展提供基础和支撑，同时需要兼顾生态保护，促进土地资源的统筹协调可持续利用。

Spatially Optimum Allocation of Land Resource in Kaysone Phomvihane City, Laos

[Objective] By optimizing the spatial allocation of land resources, the efficiency of land use can be improved, and the rational distribution of various industries and infrastructure can be promoted in order to provide a theoretical basis for the comprehensive development of the regional social economy.[Methods] The study was conducted at Kaysone Phomvihane City in Laos. GIS spatial analysis technology, logistic regression analysis, and the CLUE-S model were combined to carry out the research on the spatial optimization of land resources. Under the constraints of spatial suitability and quantity structure, model calculations were performed on the basis of land demand, limiting factors, conversion rules, and spatial characteristics to optimize the spatial allocation of land resources in Kaysone Phomvihane City.[Results] The urban construction land and paddy fields expanded to suitable areas on the original basis. The relatively sparse forestry land was developed and utilized, resulting in a moderate reduction in area. Other land types had small changes in quantity and space.[Conclusion] Urbanization and agricultural development can provide the foundation and support for the economic development of Kaysone Phomvihane City. At the same time, ecological protection should be taken into account to promote coordinated and sustainable use of land resources.
