The current status of land use in Wulushan is described. The potential land productivity was evaluated by a fuzzy comprehensive method, We take each plot as a basic unit of evaluation on the basis of an index system of land resources in Wulushan which was developed from the investigation data. Evaluation of potential land productivity is the key part of land management. A guideline is presented in this paper for a proper utilization of the land resources and to develop the productive capacity of the land.展开更多

The primary preparedness for assessment was firstly introduced.Then,it was demonstrated that the main works of assessment,including design flood by rainfall-runoff modeling in watersheds,existing flood control capacity estimation,critical rainfall and stages determination,and flood dangerous zoning for the riverside villages in mountain-hill-area in Yuzhou district. Finally,some suggestions were provided to support flash flood management in Yuzhou district,including mining information from outcomes of flash flood disaster investigation and assessment,improving the monitoring and early warning system on flash flood,and identifying potential flash flood types and areas.展开更多
