摘要

［目的］探讨土地整治规划的重要内容——土地整治分区，为确定土地整治重点区域和土地整治规划提供参考依据。［方法］以西北部生态脆弱区典型区域甘肃省兰州市为研究区域，基于生态保护视角，在充分考虑区域自然地理特征、土地利用特点及区域主要生态问题的基础上，从地形地貌、降雨、土壤类型、植被类型、水土流失、土地利用等5方面选取指标因子初步构建分区指标体系，并从水资源供给、水系分布及行政区划等方面进一步完善。同时运用ArcGIS空间叠加分析功能，使用综合分析法进行土地综合整治分区。［结果］形成了“方位+地貌+土地利用类型”命名的土地整治两级分区体系，二级分区较为详细。兰州市划分为7个一级区和15个二级区。［结论］中国西北部生态脆弱区域在土地综合整理过程中应该通过选择合理的指标体系分区进行整治。各分区应该针对其土地资源、水资源、生态环境状况等具体特征，基于生态保护视角采取有效措施进行土地综合整治。

Abstract

[Objective] To analyze the land consolidation regionalization

an important content of land consolidation planning

in order to provide basis for determining the key regional land consolidation and land consolidation planning.[Methods] We took Lanzhou City

Gansu Province

an ecological fragile area in Northwest China

as the research area. With the consideration of regional natural geographic features

land use characteristics and major regional ecological problems

a preliminary dividing index systems including terrain

rainfall

soil type

vegetation type

water loss and soil erosion was constructed. The established index systems were further improved based on regional water resource supply

water resource distribution and administrative divisions. ArcGIS spatial overlay analysis function was used.[Results] A two level regionalization system that named by the "orientation+landscape+land use type" was established

and the second level is more detailed. Lanzhou City was divided into 7 zones and 15 sub-zones.[Conclusion] The reasonable indicator systems should be selected for land remediation in the process of comprehensive land consolidation in Northwest China

and the characteristics of land resources

water resources and ecological environment conditions should also be considered for the different zones in the perspective of ecological protection.
