【目的】讨论并分析土地利用多功能性及其相互间的耦合情况,为区域土地可持续利用提供支撑。【方法】以系统论为核心指导,从土地利用现状分类和土地利用规划分区两个维度,推演土地利用多功能机理并据此构建评价指标体系,运用熵值法、模糊综合评价法、耦合协调模型和灰色关联模型,分析广西及其各市2008-2017年土地利用各功能的综合发展水平和耦合协调程度及其时空演变特征。【结果】结果表明:(1)2008-2017年,广西土地利用各功能的综合评价水平指数由0.2709上升到0.7812,各功能均得到了长足发展与进步。(2)广西土地利用各功能综合水平的排名为:文化性功能>经济性功能>社会性功能>生态性功能,土地利用过程中的生态功能尚有较大提升空间。(3)广西土地利用各功能耦合协调类型经历了“中度失调—轻度失调—濒临失调—勉强协调—初级协调—中级协调”的演变过程,在14个地级市中,以桂林、柳州和南宁为最优。【结论】广西土地利用各功能总体呈向好发展态势,各市土地利用的生态性、经济性、社会性和文化性功能的耦合协调度差异较大,发展不均衡,区内土地利用各功能间尚未形成稳定、高效的协调发展机制。为提高土地利用多功能水平,广西应以桂林市、柳州市和南宁市为核心节点,以点带面,走以文化性功能为引领,以生态性功能提升为关键,统筹社会性和经济性功能协调发展之路。 |

This paper discusses and analyzes the multi-function of land use and the coupling coordination between them, so as to provide support for the sustainable use of regional land. Under the guidance of system theory, this paper deduces the multi-functional mechanism of land use from the two dimensions of land use status classification and land use planning zoning, and then constructs the evaluation index system based on it. Using entropy method, fuzzy comprehensive evaluation method, coupling coordination model and grey correlation models, this paper analyzes Guangxi and its cities in 2008-2017 The comprehensive development level, coupling coordination degree and temporal and spatial evolution characteristics of land use functions. The results show that: (1) From 2008 to 2017, the comprehensive evaluation level index of all functions of land use in Guangxi increased from 0.2709 to 0.7812, and all functions have made great progress. (2) The comprehensive level of land use in Guangxi is as follows: cultural function >economic function > social function > ecological function. There is still much room for improvement of ecological function in the process of land use. (3) The coupling and coordination types of land use in Guangxi have experienced the evolution process of "serious maladjustment - moderate maladjustment - mild maladjustment - near maladjustment - reluctant coordination - primary coordination - intermediate coordination". Among the 14 prefecture level cities, Guilin, Liuzhou and Nanning are the best. In general, the functions of land use in Guangxi are developing well. The coupling and coordination degree of ecological, economic, social and cultural functions of land use in different cities are quite different, and the development is unbalanced. There is no stable and efficient coordinated development mechanism among the functions of land use in the region. In order to improve the multi-functional level of land use, Guangxi should take Guilin City, Liuzhou city and Nanning City as the core nodes, point to area, cultural function as the guide, ecological function as the key, and coordinate the development of social and economic functions. |
