| 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 elements of the overall land use planning. It is important to determine the future land use direction, formulate the land use structure and spatial layout adjustment strategy, and realize the regional land differentiation management and sustainable utilization. As the most important commodity grain base in China, Northeast China has a significance to the national food security. However, the economic development level of different provinces in Northeast China is quite different. The development of regional economy is unbalanced.The index system of characterizing the three-dimensional state of land use in the main grain producing areas was constructed, and the two-dimensional graph theory clustering method and GIS spatial analysis method were used to study the land use zoning of 184 county-level administrative units in northeast region, and differentiated land use regulation measures were put forward. The results showed that the three-dimensional evaluation index system of land use can clearly reflect the natural background condition, development status and future development potential of land use;the results of land use zoning in Northeast China obtained by two-dimensional graph clustering and GIS qualitative analysis had good spatial continuity as well as zoning integrity, which improved the feasibility and scientificalness of land use zoning. The northeast region was divided into twelve zones consisted of three city comprehensive development zones, two agricultural and animal husbandry land use zones, one agricultural and forestry land use zone, one agricultural, forestry and animal husbandry land use zone, five forestry and agricultural ecological zones. The research had certain reference significance for the management of land use in the main grain producing areas. |
