| 摘要: |
| 为满足自然资源发展规划的需求，本文基于山江海视角，以桂西南喀斯特区-北部湾海岸带为研究对象，采用地貌类型、地质类型、土壤类型、植被类型和土地利用要素构建了山江海地域系统关键带三级分类方案，运用空间叠置法对分类要素进行叠加和制图综合分析，并进行山江海地域系统关键带区划分类、制图和环境因子分析研究。结果表明，可将桂西南喀斯特区-北部湾海岸带划分为38个一级单元、78个二级单元、111个三级单元。一级关键带分类中海拔山地-非碳酸盐岩区占据面积最大，为19.10%；二级分类中海拔山地-非碳酸盐岩区-红壤性土占据面积最大，为13.98%；三级分类中低海拔丘陵-非碳酸盐岩区-复盐基红黏土-针叶林-河渠占据面积最大，为15.21%。研究结果表明，本文所提出的关键带综合分类方案可体现区域特征中的差异和驱动因素，因此可为自然资源地表系统规划提供理论基础，同时可为国内外相关研究提供参考依据。 |

| Abstract: |
| In order to meet the needs of natural resources development planning, based on the perspective of mountains, rivers and seas, this article takes the coastal zone of Karst Area in Southwest Guangxi-Beibu Gulf as the research object. Based on geomorphic types, geological types, soil types, vegetation types and land use elements, a three-grade classification scheme for the key zones of the mountain, river and sea territorial system was constructed. The spatial overlay method is used to overlay and map the classification elements, and the zoning, mapping and environmental factor analysis of the key zones of the mountains, rivers and seas regional system are carried out. The results show that the Karst Area in Southwest Guangxi-Beibu Gulf coastal zone can be divided into 38 primary units, 78 secondary units, and 111 tertiary units.In the first-grade key belt classification, the mid-altitude mountains-non-carbonate rock area occupies the largest area, accounting for 19.10%. In the second-grade classification, the mid-altitude mountains-non-carbonate rock area-red loamy soil occupies the largest area, accounting for 13.98%. In the third-grade classification, the area of low-altitude hilly-non-carbonate rock area-complex salt-based red clay-coniferous forest-river canal occupies the largest area, accounting for 15.21%. The results indicate that the comprehensive classification scheme for key zones proposed in this study can reflect the differences and driving factors in regional characteristics.Therefore, it can provide a theoretical basis for the planning of natural resources surface system, and at the same time, it provides a reference for relevant research at home and abroad. |
