摘 要:土地整治对土地利用空间布局优化具有重要的引导作用.本文选取北京市大兴区1∶10 000土地利用现状数据,以乡镇作为分析单元,进行空间重构方法探讨;其次从高标准基本农田建设要求出发,确定空间重构分析参数及标准值;最后对土地整治过程中存在的空间重构问题进行分析研究.结果表明:(1)大兴区各乡镇的耕地面积比例未达到60%的依次是亦庄镇、旧宫镇、西红门镇、黄村镇等,仅礼贤镇达满足要求,土地整治需通过土地利用转型解决;(2)满足高标准建设中形状指数要求的耕地斑块仅有2538块,占全区19.30%,形状指数处于1.06—1.5的比例最大;(3)农田基础设施占有率除旧宫镇、礼贤镇、榆垡镇、安定镇、庞各庄镇、魏善庄镇的农田基础设施不到8%外,其余各镇的农田基础设施占有率均已超出标准值,且以亦庄镇、西红门镇尤为严重;(4)大兴区大于13.3hm2以上的耕地斑块数共705块,占全区总斑块数的5.36%,需通过小块并大块实现耕地集中连片,以达到区域农业规模化生产.Land consolidation and rehabilitation plays an important role of guiding on the optimization of spatial distributing of farmland. This paper selected land use data of Daxing District at the scale of 1∶ 10000 as a case study,and analyzed the problem of spatial restructuring existing in construction of well-facilitated capital farmland. The results show that( 1) Area proportion of farmland in most townships in Daxing District does not reach 60%. The townships which have the biggest difference between the proportion of farmland in Daxing and 60% were mainly located in Yizhuang,Jiugong,Xihongmen,Huangcun,etc. Only Lixian township achieves this area ratio. Land remediation can be resolved through the transfer of land use types.( 2) There are only 2538 patches meet the construction requirements of well-facilitated capital farmland in the all townships in Daxing District,which account for 19. 30% of the total patches of farmland.( 3) Occupancy of farmland infrastructure in the study region is 8. 46%,which exceeds the standard value of 0. 46%. In addition to the townships of Jiugong,Lixian,Yufan,Anding,Panggezhuang,Weishanzhuang,the occupancy of farmland infrastructure is less than 8%.( 4) There are only 705 patches meet the construction requirements of well-facilitated capital farmland in the all townships in Daxing District.
