This essay is intended to discuss the relationship of land consolidation and eco security in hilly and mountainous regions of Southwest China based on the development trends of land consolidation at home and abroad and from the angle of target regional division of labour of land consolidation. It points out, as a typical eco friable region, to ensure the eco security is the first important target of land consolidation in the hilly and mountainous regions of Southwest China. The regional eco location is especially important because it is located in the upper reaches or headwaters of great rivers such as Changjiang, Zhujiang, Lancang rivers, etc. and it is one of the typical regions with plentiful biodiversities. Investigation and analysis indicate that not only the natural ecosystem is vulnerable in the hilly and mountainous regions of Southwest China, but also it's the role of eco protective screen is weakening.For example, the reality rate of forest coverage is far more low the theory lowest vegetation cover rate in Southwest China except Yunnan province. Thus, the regional eco security, especially the land resource security is facing numerous threats. As a natural water collecting unit and an integral land ecosystem, it is regarded the small watershed land consolidation is the representative pattern of land consolidation to ensure the safety of the regional land resources and regional eco security and realize regional sustainable development of the hilly and mountainous regions in Southwest China.The model's core concept is to allot different land consolidation countermeasures suitable for the features and ideal function of different landform positions of small watershed in order to realize different targets of land consolidation. That is to say, to arrange the macro countermeasures of land consolidation according to the special characteristics of the land ecosystem of small watershed, such as to adjust the land use structure, and allocate micro countermeasures of different standard according to the features of different landform positions, such as to close hillside to facilitate afforestation in the watershed regions, to return farmland to forest and grassland on steep slopes exceeding 25 degrees,to build terraced fields in areas where the slope ranges from 8~25 degrees, and to develop flood land.
