摘要
[目的]探索提高县(市)尺度农用地整治新增耕地潜力评价效率、精度,降低评价成本的方法,为土地利用总体规划和土地整治专项规划提供参考。[方法]以GIS全域空间分析方法为主的农用地整治新增耕地潜力评价技术方法体系,即基于区域"二调"更新、土地利用总体规划、农用地整治经验等国土数据成果,在现阶段县/市尺度农用地整治新增耕地潜力评价技术思想及技术原则下,先确定待整治农用地规模,再测算新增耕地面积,最后计算新增耕地系数,进而进行新增耕地潜力类型区划分。[结果]温州市农用地整治新增耕地潜力测算结果合理,且具有较强的实用性。[结论]该技术方法体系实现了从基础图件数据输入整理、到潜力测算评价、再到成果图表输出的程序化操作,不仅有效提高县/市尺度农用地整治新增耕地潜力评价效率,降低评价成本,而且紧密衔接于当前土地管理工作实际,具有较高的推广应用价值。
[Objective] The aims of this study are to increase the efficiency and accuracy of the potential evalu- ation of newly-increased cultivated land from farmland consolidation on the scale of county(city), reduce the cost of the evaluation, and to provide reference for the overall planning of land use and land remediation planning. [Methods] A new technical system based on the GIS spatial analysis method was used. Based on data from the second investigation of land-use and the general land use planning, combined with the experience from land consolidation, we first developed new principles and perspectives for the potential evaluation, then determined the scale of agriculture land to be processed, then measured the area of the newly-increased farmland, and then calculated the coefficient of newly-increased farmland, finally delineated the fivepotential zones. [Results] The potential of newly-increased cultivated land from farmland consolidation in Wenzhou City is reasonable and more practical. [Conclusion] The empirical study showed that the technical system could provide a proceeding operation of inputting the basic data, measuring and evaluating the potential, and outputting the results. Such technical system not only has the advantages of improving the efficiency and reducing the cost of the potential evaluation at the same time, but also well adjusts the current land management practice, which presents considerable promotional value.
