| The Lake Erhai Watershed is located in Southwestem China with an area of around 2,500 km{dollar}sp2.{dollar} There exist a number of human activities, such as agriculture, industrial productions, tourism, forestry, net-cage fish culture and lime/brick productions. Lake Erhai, with its freshwater resources, has been playing a vital role in the local socio-economic development. However, the watershed is now confronted by many environmental problems, especially the degradation of the lake water quality due to the discharge of human-made contaminants. The purpose of this research is to provide a plan for sustainable development of the Lake Erhai Watershed with a special emphasis on the lake water quality protection.; As a large-scale regional water quality management system, the Lake Erhai Watershed is associated with multiobjective, uncertain, dynamic and interactive features. There has been no study for the region which simultaneously considered all these complex features. From a methodology point of view, the existing approaches for multiobjective programming under uncertainty are limited by a number of difficulties. Consequently, a hybrid inexact-fuzzy multiobjective programming (IFMOLP) method is proposed and applied to the project for the Lake Erhai Watershed. (Abstract shortened by UMI.)... |
