中国西北部生态脆弱区典型区域土地综合整治分区--以甘肃省兰州市为例
Division on Land Consolidation of Typical Area for Ecological Fragile Area in Northwest China- A Case Study in Lanzhou City of Gansu Province
摘要
Abstract
[Objective] To analyze the land consolidation regionalization ,an important content of land consoli‐dation planning ,in order to provide basis for determining the key regional land consolidation and land consol‐idation 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 charac‐teristics and major regional ecological problems ,a preliminary dividing index systems including terrain ,rain‐fall ,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 administra‐tive divisions .ArcGIS spatial overlay analysis function was used .[Results] A two level regionalization sys‐tem 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 indica‐tor 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 con‐ditions should also be considered for the different zones in the perspective of ecological protection .关键词
