    摘要:

    国土综合整治与生态修复对保障区域生态质量、优化生态安全格局和提升生态系统服务功能有积极的促进作用,优化分区是国土综合整治与生态修复工程安排中不可或缺的重要环节。本文以广西壮族自治区贺州市昭平县为例,提出了基于潜力 - 动力 - 压力框架的县域国土综合整治与生态修复分区方法,研究结果表明:国土综合整治潜力从农用地整理潜力、土地开发潜力等方面进行分析,生态修复潜力从植被恢复潜力、水源涵养潜力、防风固沙潜力和生物多样性潜力方面进行分析,各潜力空间分布不均匀;国土综合整治与生态修复动力中,归一化植被指数和林地覆盖率总体水平较高,草地覆盖率北部高于南部,水域面积比西部高东部低,建设用地面积比空间分布不均衡;国土综合整治与生态修复压力中,人均耕地面积南部高于北部,地均生产总值东部高于西部,农村居民人均纯收入西北高东南低;分区结果显示,昭平县 1 个乡镇属于优先整治修复区,4 个乡镇属于重点整治修复区,7 个乡镇属于适度整治修复区。研究结果可为区域国土综合整治与生态修复的工作部署与工程布局提供重要指导。

    Abstract:

    Comprehensive consolidation and ecological restoration have a positive promoting effect on ensuring regional ecological quality, optimizing ecological security patterns, and enhancing the value of ecosystem services. Zoning of comprehensive consolidation and ecological restoration of land space is an indispensable and important part of the arrangement of projects. Taking Zhaoping County, Hezhou City, Guangxi Zhuang Autonomous Region as an example, a zoning method of comprehensive consolidation and ecological restoration of land space was proposed based on Potential-Motivation-Pressure framework for county-level. The main conclusions were as follows: the potential of comprehensive consolidation was mainly analyzed from the aspects of new arable land potential, arable land quality improving potential, land development potential, land reclamation potential, rural construction land potential and urban construction land potential. While the potential of ecological restoration was mainly analyzed from the aspects of vegetation coverage potential, water conservation potential, windbreak and sand fixation potential and biodiversity potential. In the motivation index, the overall level of normalized difference vegetation index was relatively high, the overall level of forest coverage was relatively high, and the grassland coverage rate was significantly higher in the north than that in the south. The distribution pattern of water area ratio was higher in the west and lower in the east, and the spatial distribution of construction land area ratio was uneven. In the pressure index, the per capita arable land area was higher in the south than that in the north, the per capita GDP was higher in the east and lower in the west, and the per capita net income of rural residents was higher in the northwest and lower in the southeast. Zoning of comprehensive consolidation and ecological restoration of land space showed that there was one town in Zhaoping County that belonged to the priority rectification and restoration area, four towns that belonged to the key rectification and restoration area and seven townships that belonged to the moderate rectification and restoration area. The research results had important guiding significance for the arrangement and engineering layout of comprehensive consolidation and ecological restoration of land space.
