广西西江流域“三生用地”时空分异特征研究

Study on Spatial and Temporal Differentiation Characteristics of Ecological-Living-Industrial Land of the Xijiang River Drainage Basin in Guangxi

研究以土地利用的多功能性为切入点,基于土地利用现状分类构建了"三生用地"分类体系,将广西西江流域2005年与2015年两个时间点的土地利用现状从空间上分为了生产生态用地、生态生产用地、生态用地及生活生产用地四大类,并针对其利用情况对各个类型的三生分类用地提出了相应的优化配置方案。研究表明,广西西江流域各类功能用地面积差异较明显,且分布较为不均匀,生态环境保护情况良好,生态生产用地广泛分布于整个西江流域,在西北部地区占比相当大,大部分生产生态用地及生活生产用地集中在西江流域中南部,生活生产用地占比较少。

Taking the versatility of land use as the starting point, this paper constructs the classification system of ecologicalliving-industrial land based on the classification of land use status. The land use status of Xijiang River Basin in Guangxi in 2005 and 2015 is spatially divided into four categories: Production ecological land, ecological production land, ecological land and living production land. According to its utilization, this paper puts forward the corresponding optimal allocation scheme for each type of ecological-livingindustrial classification land. The research shows that the difference of various functional land area in the Xijiang River drainage basin of Guangxi is obvious, and the distribution is relatively uneven. The ecological environment protection is good. The ecological production land is widely distributed in the whole Xijiang River Basin, which accounts for a large proportion in the northwest. Most of the production ecological land and the living production land are concentrated in the south central part of Xijiang River Basin, while the living production land accounts for a small proportion.
