大型水电工程胁迫下川西高山地区土地整理模式——以甘孜州泸定县为例

探讨在大型水电工程相继修建的前提下的川西高山地区土地开发整理模式,做到有效增加耕地面积,提高土地利用效率,妥善安置移民。采取实证研究和规范研究相结合的方法进行研究。研究结果表明,川西高山地区土地整理模式可采用工程防护模式、开发未利用地模式、生物工程模式和土地平整模式等。川西高山地区土地整理必须突破水利设施、土壤改造和施工条件差等3项限制性因素,从土地整理的社会效益、经济效益和生态效益的综合体进行整体效益评价。

Menacing by Big Hydropower Project on Land Consolidation Models of High Mountainous Regions in West Sichuan——Case Study of Luding County, Ganzi Zang Autonomous Region

The purpose of the paper was to search for the models of land consolidation,effectively to increase the area of farmland,to improve land-use efficiency on the condition of menacing by big hydropower project.Integrated approach of empirical and normative research was employed.The results indicated that the models of land consolidation in west Sichuan had the engineering-protecting model,developing unused land,bio-engineering model and land consolidation modle for use.Conclusions were drawn as follows:it was necessary that broke through the restrictive factors in west Sichuan mountainous regions,such as the shortage of watersoil reconstruction and conditions of construction bad.It was necessary that the benefit of ecology,economy and society were concerned synthetically when the model of land was consolidation.
