摘要: 土地整理生态环境评价及其时空配置是进行区域土地整理的科学基础.文中以山东省青州市为例,在深入分析土地整理特点和青州市自然社会条件的基础上,构建了土地整理生态环境评价指标体系和评价模型;运用综合指数法和GIS技术取得各评价单元综合得分,在此基础上进行了区域土地整理时空配置.结果表明,青州市耕地和未利用地共1 446 km2,近期土地生态环境整理区主要分布于平原区的西北部,占耕地和未利用地总面积的15.35%,中期整理区分布于平原区的西北部和中部,占13.58%,远期整理区分布在平原区的北部,40.71%,不整理区分布于丘陵区,占30.36%.研究结果可为青州土地整理规划和实施提供科学依据.

Abstract: Eco-environmental evaluation and spatial-temporal collocation of land consolidation is the basis of regional land consolidation. Taking Qingzhou County of Shandong Province as an example, this paper established the eco-environmental evaluation index system and evaluation model of land consolidation, based on the systematic analysis of land consolidation characteristics and natural and social conditions of Qingzhou County. The comprehensive score of each evaluation unit was obtained by integrated index evaluation method and GIS techniques, and the spatial-temporal collocation of regional land consolidation was proposed accordingly. The results indicated that in Qingzhou County, the total area of cultivated and un-utilized land was 1 446 km2, among which, the land consolidation area in near future mainly distributed in the northwest part of plain region, occupying 15.35% of the total, mid-phase land consolidation area mainly distributed in the northwest and central parts of plain region, occupying 13.58%, land consolidation area in specified future mainly distributed in the north part of plain region, occupying 40.71%, and non-land consolidation area mainly distributed in hilly region, occupying 30.36%. These results could provide scientific instruction for the land consolidation planning and implement in Qingzhou County.
