A study on regional forced land use convertion and optimal allocation --Taking the Three Gorges Reservoir Area as an example
区域土地利用类型的胁迫转换与优化配置—以三峡库区为例

The structure and layout of land use have been greatly changed because of the low lying land submergence,resettlement,movement of new towns and industrial and mining enterprises resulting from the construction of the Three Gorges Reservoir Area(TGRA).Therefore,how to construct the new macro patterns of land use types according to the principle of landscape ecology and sustainable developmental norm are not only the keystone of resettling a million of migrants and allocation of production in TGRA in the next ten years,but also are related to harmonious and sustainable development of economy,society,resources and environment in the future.In this paper,the ways and process of conversion of land use types under the forced conditions including land submergence and use allocation are analyzed.Then,with a view to different hierarchies from factor controlling,zone design to optimal system models,the models and measures of land eco design are put forward.Based upon which,considering the harmonious development of industries,the optimal allocation schemes of land use are formulated.
