摘　　要：土地利用功能分区是国土空间开发保护与利用的重要前提。将最小累积阻力模型引入广西贺州市土地利用功能分区研究中,基于阻力约束视角开展建设用地、生态用地、农业用地扩张阻力评价,通过分析不同用地扩张的适宜性划分土地利用功能区。结果表明:(1)生态用地扩张阻力以各生态保护源为中心向四周扩张,农业用地扩张阻力由贺州市中部向四周递增,建设用地扩张阻力呈中部低、四周高的特点;(2)依据各类用地扩张的适宜性将贺州市划分为生态保护核心区、农业生产核心区、建设开发核心区、生态保护涵养区和生产生态拓展区,其空间分布与贺州市现状用地布局相符且契合相关规划的用途分区及管控要求。与传统适宜性评价相比,基于扩张阻力评价的适宜性分析综合考虑了各用地类型的垂直自然要素和水平扩张作用,为具体的土地利用功能分区提供了更为科学的依据;研究明确了各功能区的分布并提出对应的发展建议,能够为贺州市土地利用结构优化提供依据与指导。Land use functional zoning is an important prerequisite for the protection and utilization of land space development.The MCR model is introduced into the study of land use functional zoning in Hezhou City based on the perspective of resistance constraints.Evaluation of resistance to expansion of construction land,ecological land,and agricultural land,and divide land use functional areas by analyzing the versatility of expansion of different land types.The results show that:(1)The expansion resistance of ecological land is expanded to the surrounding areas with each ecological protection source as the center,the expansion resistance of agricultural land increases from the central part of Hezhou City to the four sides,and the expansion resistance of construction land shows the characteristics of low in the central region and high in the surrounding areas;(2)According to the suitability of various types of land expansion,the whole area of Hezhou City is divided into five categories:ecological protection core area,agricultural production core area,construction and development core area,ecological protection and conservation area,and production ecological expansion area.Its spatial layout is consistent with the current land layout of Hezhou City and is in line with the use zoning and control requirements of relevant planning.Compared with traditional suitability evaluation,the multi-suitability analysis based on the MCR model comprehensively considers the vertical natural elements and horizontal expansion effects of each land use type,and provides a more scientific basis for the specific land use functional zoning.The thesis clarifies the distribution of each functional area and puts forward corresponding development suggestions,which can provide basis and guidance for land use structure optimization in Hezhou.
