As a political, economic and cultural center of the Tibet Autonomous Region, the Lhasa River needs to take planning and management of the basin. In the past 60 years, the temperature of Lhasa River Basin has been increasing gradually at an annual rate of 0.047 ° C, which leads to the water cycle variation of the river basin and its associated aquatic ecology and environment continue to change and evolve, and ecological environmental protection is affected by more uncertain factors. Based on the assessment of the ecological environment of the Lhasa River Basin, the comprehensive planning suggestions for the Lhasa River Basin were proposed from the aspects of water environment, land use, ecological pattern, and economic and social development. These suggestions are drawn on the examples of integrated planning and management of catchment in foreign countries and are referred to as the comprehensive planning of the seven major river basins in China.

The goal of this paper is to tackle joint decisions in assigning production and organizing transportation for single product in a production-transportation network system with multiple manufacturers and multiple demands. In order to meet practical situation, assume that the variant costs and the amounts of the consumption of raw materials that every manufacturer produces per unit product are all uncertain variables in manufacturing processes; meanwhile, the demands that each destination needs are random variables in the transportation problem. Then, a joint optimization model of production and transportation is developed, in which the uncertain chance constraint and the stochastic chance constraint are applied in the manufacturing processes and the transporting processes, respectively, and transformed into a deterministic form by taking expected value on objective function and confidence level on the constraint functions. Finally, a practical example points out the effectiveness of our model.
