基于系统论的山区县土地多功能利用空间格局及权衡/协同

    Spatial patterns and trade-offs/synergy analysis of multifunctional land use in mountainous counties based on system theory

    • 摘要: 土地功能是土地本身所特有的能力,基于土地作用视角下土地功能的分类进行研究,有利于明确区域发展基础及发展潜力。厘清土地多功能权衡/协同关系,是实现土地多功能协同开发,推动区域土地资源高效利用的关键。该研究基于土地作用视角下土地功能的分类,以河北省阜平县为研究区,采用空间分析和相关性分析等方法,从村域尺度出发,对阜平县土地多功能进行评价、空间可视化以及相关性分析。结果表明:阜平县土地各功能在空间分布上存在着不同规律;阜平县土地多功能在总量上和结构上存在相反的空间分布格局,阜平县土地各功能间的协同程度较低;村域视角下的阜平县土地多功能权衡/协同研究,6种功能的15种两两组合中仅有生态功能和原材料供给功能之间存在权衡关系,其余均为协同关系,其中景观功能和支撑功能间的协同作用最为显著,两种功能间的相关系数为0.6431。该研究进一步完善了土地多功能研究体系,为阜平县土地资源高效利用和管理策略的制定提供了参考依据,同时,相关研究结果也可为土地资源管理领域提供参考。

       

      Abstract: Land function is the unique ability of land itself, and research based on the classification of land function under the perspective of land role is conducive to clarifying the basis of regional development and development potential. The multifunctional use of land represents an effective strategy for addressing the scarcity of land resources and for enhancing their overall value. The examination of the spatial distribution pattern of multifunctional land use enables the grasping of the spatial development status of multifunctional land use in a detailed and intuitive manner. Furthermore, the clarification of the multifunctional trade-offs and synergistic relationships of land use facilitates the understanding of the impacts of each function, which can contribute to the configuration and layout of future territorial spatial planning. This paper selects Fuping County of Hebei Province as the study area based on the classification of land function under the perspective of land role. Previous research results are referenced and the resource allocation and actual situation of Fuping County are combined with the objective of selecting appropriate land element factors as evaluation indexes. The resulting evaluation index system is then constructed. In order to quantify and analyse the multifunctionality of land, two distinct approaches were employed: the weighted composite index method and Simpson's inverse index method. These were used to assess the extent to which land exhibits multifunctionality in a quantitative and structural manner. Furthermore, Pearson's correlation analysis and bivariate local Moran's index were utilised to examine the quantitative relationship and spatial correlation of multifunctional land use. The results show that: (1) The spatial distribution of land functions in Fuping County is subject to a number of influences, including natural and other factors, which give rise to a variety of patterns. (2) The spatial distribution of land multifunctionality in Fuping County exhibits contrasting patterns in terms of total volume and structure, indicating a low level of structural synergy between land functions within the county. In terms of total volume, the multifunctionality of land in Fuping County exhibits an overall spatial distribution pattern of “low in the centre and gradually increasing towards the north and south”. With regard to its structural characteristics, the multifunctionality of land in Fuping County is characterised by a spatial distribution pattern of “high in the centre, gradually decreasing towards the north and south”. (3) The study of land multifunctional trade-offs/synergy in Fuping County at the village scale revealed that, among the 15 two-by-two combinations of six functions, only the ecological function and raw material supply function exhibited trade-offs, while the remaining combinations were synergistic. These included the landscape function and supporting function, the production function and supporting function, and the historical record function and supporting function. The production function and historical record function, the historical record function and supporting function, the production function and landscape function, and the five combinations of these five synergistic relationships are more pronounced. Furthermore, the landscape function and supporting function, and historical record function and supporting function demonstrate synergistic relationships across the majority of Fuping County, accounting for 52%. This equates to 47% and 52.61% of the total area, respectively. This study represents a further improvement to the land multifunctional research system and provides a reference basis for the development of land resource utilisation and management strategies in Fuping County. Furthermore, the relevant research results can be applied to land resource management fields such as the optimal regulation of national land space.
