Taking Tunchang County in Hainan Province as a case study, dual self-organizing model accounting for geographical space as well as attribute space, was proposed. The geographic space information included the longitude and the latitude of the administrative villages. These indices such as the potential, the urgency and the feasibility were combined to construct the attribute space. The results demonstrated that the potential, the urgency and the feasibility of land reclamation were quite different among the villages. The model scores for the villages were significantly higher in the southern region than that in the northern region, and they were higher in the eastern region than that in the western region. The most desired land reclamation projects would be carried out in Poxin Town, Nankun Town, Xichang Town, Tuncheng Town. The 161 villages were divided into 6 project regions through dual self-organizing model. Based on the comprehensive score, the 6 project regions were classified into three types: priority remediation area (near-term), key remediation area (medium-term) and moderate remediation area (long-term). The area percent of three types were 25.14%, 41.83% and 33.03%, respectively. The developing orientations and suggestions for the land reclamation projects were given according to the characteristics of different influence factors. The results provide the scientific foundation in planning and implementing the project of land reclamation in Tunchang County, and is helpful in improving the level of land consolidation planning as well as promoting the land reclamation progress and the sustainable development.

以海南省屯昌县为例, 构建兼顾地理空间和属性空间的双重自组织模型, 对土地整治项目区进行时空配置。地理空间采用行政村几何中心点的 x, y坐标表示, 属性空间采用土地整治潜力、土地整治迫切性和土地整治可行性表示。结果表明, 屯昌县各行政村土地整治潜力、土地整治迫切性和土地整治可行性空间差异显著, “南高北低”和“东高西低”特征明显, 亟需开展土地整治项目的有坡心镇、南坤镇、西昌镇和屯城镇等。采用双重自组织模型, 将 161 个行政村划分为 6 个土地整治项目区。基于综合评价得分, 将屯昌县划分为优先整治区(近期)、重点整治区(中期)和适度整治区(远期), 面积比例分别为 25.14%, 41.83%和 33.03%, 并提出不同土地整治分区的目标导向和整治建议。研究结果可为屯昌县土地整治项目规划与实施提供科学依据, 同时对提高区域土地整治规划水平、促进土地整治事业可持续发展具有积极作用。
