%X Watershed, a kind of complex huge system incorporating lots of constituents, demands proper methods to carry out integrated planning so as to guide its sustainable development. In this paper, an integrated approach, the Inexact Multiobjective Programming (IMOP) model is promoted to solve the problem. The IMOP improves upon the existing multiobjective programming methods, such as fuzzy/stochastic MOP methods. It can bring the system components into a single framework, and efficiently coordinate and optimize objectives. Also it can better address system uncertain features, especially considering that it allows uncertainty presented as interval numbers to be directly communicated into modeling process without necessarily known possibilistic or probabilistic information. IMOP is regarded as a useful tool for system analysis and optimization, and it has already been widely employed worldwide to solve many optimization problems. It can reconcile multiple and conflicting objectives scientifically and deal with the insufficient and inexact information effectively as well. At the meantime, watershed system is characterized by dynamic, multi-objective and information insufficiency. Therefore IMOP is suitable to the watershed planning and optimizing. Resting on the watershed's characteristics, the Inexact Multi-Objective Programming on Watershed Economic-Environmental System (IMOPWEES) model is built and applied to Lake Qionghai Basin, Sichuan Province. In the case study, the optimum schemes in different periods under different scenarios are obtained. Moreover, the aspects of the plant structure, tour-service structure, water resource allocation, pollutants discharging, forest expanding and soil erosion are particularly considered in the paper to demonstrate the results and the scenario analyses. The study fully indicates the effectiveness, practicality and operability of the IMOPWEES model and its applicability to the integrated planning of watersheds. Undoubtedly, it also provides a good means for the related researches.
