Abstract:

This paper explored land environmental issues in Three Gorges Resettlement Area, taking Wushan County as a case. Having summarized the major land environmental problems as well as their causes in the Wushan Resettlement, the paper set six river basins as its research units and chose eight representative factors of environmental risk from three aspects of ecosystem risk, social risk and environmental pollution risk. The paper made a risk evaluation of land environmental problems in the regions by employing Delphi method and Analytic hierarchical programming(AHP), and proposed a pattern of eco- friendly utilization in the regions for the sake of their sustainable development.

Key words: land ecological security, patterns of eco- friendly utilization, resettlement, risk evaluation, Three Gorges
