    摘要:

    [目的] 以典型岩溶地貌及全国南部生态廊道相对发育与密度较高的柳州市为例,对自然空间进行精准分区并提出管制办法,为其他喀斯特地区研究提供科学参考。[方法] 基于空间叠置法、INVEST模型与最小累积阻力模型,提取全域尺度生态廊道,构建区域生态安全格局,实现自然资源空间精准分区。[结果] ①生态源区以大型林地为主,面积达3 531.24 km2,总体呈中部向南北部递增的趋势;②生态廊道呈以主要廊道为依托,次要廊道为承接的环状分布结构;③依据生态安全格局构建结果及自然地理特征将柳州市自然资源空间划分为禁止开发建设、限制开发建设、允许开发建设、优先开发建设4个管控区,并按照区域生态环境问题与空间主导功能提出差异化管制方法。[结论] 以生态安全格局为依据划分自然资源空间管制区,各管控区发展定位与目标差异较大,要实行差别化管制,促进区域的可持续发展。

    Abstract:

    [Objective] The natural resource space of Liuzhou City, which is located in Southern China with typical karst landform and relatively high development level and density of ecological corridors was accurately divided and a control method was proposed in order to provide a scientific reference for research in other karst areas. [Methods] Based on the spatial superposition method, the INVEST model, and the minimum cumulative resistance model, global scale ecological corridors were extracted, the regional ecological security pattern was constructed, and the precise spatial division of natural resources was determined. [Results] ① The ecological source region was dominated by large woodland with an area of 3 531.24 km2, and exhibited an overall increasing trend of fields from the central area to the south and to the north; ② The structure of ecological corridors was distributed in a ring shape that was supported by the main corridors and connected by the minor corridors; ③ According to the finished construction of the ecological security pattern and the natural geographical characteristics of Liuzhou City, the natural resources of this city were divided into four controlling areas: areas where development and construction are forbidden, areas where development and construction are restricted, areas where development and construction were permitted, and areas where development and construction were a priority. Differentiated control methods were proposed in accordance with regional ecological environment problems and spatially dominant functions. [Conclusion] The natural resource space control zone was divided on the basis of the ecological security pattern. The development positioning and goals of each control zone were quite different. Differentiated control must be implemented to promote sustainable development of the region.
