| 摘 要： | 耕地整理类型区与整理区优先度划分是土地整理规划的基础。该文以北京大兴区为例，充分利用农用地分等成果，从耕地整理的基本目标出发，分析选取了土地整理类型区划分的因子，并运用模糊聚类方法划分整理类型区；提出了基于土地整理效益与评价单元对新增耕地和提高耕地综合生产能力的迫切性需求的双重目标的土地整理优先度评价指标体系和方法。结果表明，研究区内耕地最主要的限制性因素是土壤肥力偏低，亟需培肥地力的区域耕地面积为27 603.8 hm2，占总耕地面积的64.9%；其次是耕地地块的坡度、规模和景观指数等因素导致的耕地生产条件差，而需要实施整理工程的耕地占总耕地面积的17.86%；近期整理区分布与新增耕地相关的整理类型相一致，占区域总耕地面积的15.82%；中期整理区集中连片分布在该区的北部地区，占区域总耕地面积的46.18%；远期整理区在较长时间内以实施培肥地力工程为主，将来主要通过居民点和闲散用地整理增加耕地面积。研究结果可为区域土地整理规划编制和土地整理实践提供科学依据。

| Abstract: | Delineating arable land consolidation (LC) zones and the degree of priority zones is the basic work for LC planning. Taking Daxing district in Beijing as an example, the factors were chosen for arable LC zoning based on LC targets, and the fuzzy cluster were used for zoning LC types. Based on the dual-objectives, that are the LC benefits and the press for increasing arable land area and improving integrated production abilities, the evaluation factors and methods to determine the priority degree of LC were studied. The results show that: 1) the most serious restrictive factor is the lowest soil fertility, and the area of arable land which is urgent to cultivate the fertility is 27 603.8 hm2, occupying 64.9% of the total arable area in this region; 2) the bad production conditions caused by the unsuited gradient, little scale and irregular shape of arable land parcel is the second serious restrictive factor, and the area needed to implement consolidate project is 17.86% of the total arable area in this region; 3) the near LC zones is consistent in distribution with the area related with consolidation to increase arable land area, occupying 15.82% of the total arable area in this region, metaphase LC area occupying 46.18% distributes convergent and continuously in the northern Daxing, and the targets of LC in the long-term LC area is to increase arable land area by consolidating the rural residential area and unused land, while the main measurement is to maintain and cultivate soil fertility in a long term. The results can provide scientific instructions for regional arable LC planning and practice. |
