【摘要】：土地利用分区是土地利用总体规划的基础和关键内容,对于确定区域未来土地利用方向、制定土地利用结构与空间布局调整策略,实现区域土地差异化管理与可持续利用具有重要意义。本文通过构建表征粮食主产区土地利用"本底-现状-潜力"三维状态的指标体系,运用两维图论聚类法对东北地区184个县级行政单元进行土地利用分区研究,并提出差异化的土地利用调控措施。结果表明:土地利用"本底-现状-潜力"三维评价指标体系可以清晰地反映土地利用的自然本底条件、开发现状和未来发展潜力特征;两维图论聚类法和GIS定性分析法相结合得到的东北地区土地利用分区结果具有较好的空间连续性和区划完整性;将东北地区划分为城市综合发展区(3个)、土地利用区(2个农牧、1个农林和1个农林牧)和林农生态区(5个),针对不同类型区采取不同的土地利用指标调控措施。
[Abstract]:Land use zoning is the basis and key content of the overall land use planning. In order to determine the future land use direction of the region, the adjustment strategy of land use structure and spatial layout is formulated. It is of great significance to realize regional land differentiation management and sustainable use. In this paper, by constructing the index system of "background, actuality and potentiality" of land use in main grain-producing areas, the land use zoning of 184 county-level administrative units in Northeast China is studied by using two-dimensional graph theory clustering method. And put forward the differentiated land use control measures. The results show that the three dimensional evaluation index system of land use "background-present-potential" can clearly reflect the natural background conditions of land use, the development status quo and the characteristics of future development potential; The results of land use zoning in Northeast China obtained by the combination of two dimensional graph theory clustering method and GIS qualitative analysis method have good spatial continuity and regionalization integrity. The northeast area was divided into urban comprehensive development area (3), land use area (2 agriculture and animal husbandry, 1 agriculture, forestry and animal husbandry) and forestry ecological region (5). Different land use index adjustment measures were adopted for different types of areas.
