摘　　要：土地整治分区是土地整治规划的重要内容,可为确定土地整治重点区域和土地整治规划提供参考依据。本文围绕土地整治分区的目的,系统探讨了黄土台塬土地整治分区的原则、标准和依据,结合"形态+物质+成因"的分类体系对黄土台塬进行空间信息提取,从自然资源、台塬特征、土地整治限制因素等3个层面,自上而下、逐级细化形成土地整治三级分区体系,将黄土台塬分为4个宏观地貌一级区、11个形态影响二级区和20个条件限制三级区,并就各三级分区的分布、特征及土地整治限制条件等进行分析,提出了相应的整治重点和土地整治模式。Land consolidation regionalization means considering the diversity of regional natural resources, socio-economic conditions, agricultural farming systems and land use restrictions, and then dividing one area into several sub-zones comprising the same land consolidation type, direction and project measures. As an important part of land remediation programming, land consolidation regionalization provides a basis for determining priority areas and main direction of land remediation. Here, we give a brief overview of previous research on land consolidation regionalization and then present an explicit definition. We systematically study the principle, criteria and basis of land consolidation and extract the Loess Platform using the classification system of ＇shape ＋ material ＋ causes＇. Given the particularity of the Loess Platform landscape, as well as the goals and direction of regional land remediation, we establish a three-level regionalization system for the Loess Platform from up to down, detailed step by step according to three analysis dimensions （natural resource, feature of Loess Platform and limiting factors of land remediation）. In accordance with this regionalization system, we divided the Loess Platform into four first-level macro landform zones, 11 second-level form-affected zones and 20 third-level condition-restricted zones and analyze the distribution, character and limiting factors of these sub-zones to determine key patterns of land remediation. This research will provide a reference for land remediation within the region, and some limitations of this study are discussed.
