基于土地整治适宜性评价的全域土地综合整治潜力分析——以上饶市郑坊镇为例

Potential Analysis of Comprehensive Territorial Land Consolidation Based on Land Consolidation Suitability Evaluation: A Case Study of Zhengfang Town, Shangrao City

  • 摘要: 全域土地综合整治是优化国土空间格局、落实耕地保护任务的重要抓手。针对当前整治潜力评估中缺乏系统性技术路径的问题,本文以江西省上饶市广信区郑坊镇为实证区域,从适宜性评价切入,综合运用GIS空间分析与典型地块调查法,构建“评价—识别—调查”的潜力分析路径。结果表明:广信区郑坊镇整治潜力总面积为666.53hm2,以耕地提质改造为主,空间上集中于镇域中部和北部地势平坦、耕地连片区域;结合乡镇规划与农户意愿,可进一步将潜力图斑细化为高标准农田新建与改造、补充耕地、建设用地整理等子项目类型。典型地块调查验证了潜力分类的总体可靠性,但局部地块在土地平整度、灌溉排水等工程细节上仍存在差异。本文提出的分析路径能够有效识别整治潜力,并通过规划与意愿协同机制实现子项目科学划分,可为全域土地综合整治的潜力评估与标准化实施提供理论框架与实践参考。

     

    Abstract: Comprehensive territorial land consolidation is a critical lever for optimizing territorial spatial patterns and fulfilling cultivated land protection mandates. Targeting the absence of a systematic technical framework in current consolidation potential assessment, this paper takes Zhengfang Town, Guangxin District, Shangrao City, Jiangxi Province as the empirical study area. Starting from suitability evaluation, it comprehensively adopts GIS spatial analysis and typical plot survey methods to construct an 'evaluation-identification-investigation' potential analysis workflow. The results show that the total consolidation potential area of Zhengfang Town, Guangxin District is 666.53hm2, dominated by cultivated land quality improvement and transformation, and spatially concentrated in the flat, contiguous cultivated land areas in the central and northern parts of the town. Combined with township planning and farmers' willingness, the potential patches can be further subdivided into sub-project types including high-standard farmland construction and upgrading, supplementary cultivated land, and construction land consolidation. Typical plot surveys verify the overall reliability of the potential classification, while local plots still present discrepancies in engineering details such as land leveling, irrigation and drainage. The analysis path proposed in this paper can effectively identify consolidation potential, and realize scientific sub-project division through the collaborative mechanism of planning and public willingness, which can provide a theoretical framework and practical reference for the potential assessment and standardized implementation of comprehensive territorial land consolidation.
