Based on the essential principle of sustainable development, this paper puts forward a general idea on water resources optimization and eco-environmental protection in Qaidam Basin, and identifies the competitive multiple targets of water resources
optimization. According to the Multiple Targets Decision by the Closest Value Model, the best plan of water resources optimization, eco-environmental protection and sustainable development in Qaidam Basin is finally decided.

Les AA. utilisent la technique du contrôle optimal dans le cadre d'un modèle dynamique d'équilibre, afin de déterminer le rôle de la politique publique locale (fiscalité et dépenses) dans la création des avantages comparatifs de certaines régions
Optimization requires equilibrium flow to decrease under mild congestion, but increase under hypercongestion. However, both increasing flow needed under hypercongestion and decreasing flow needed under mild congestion should be accompanied
by decreasing density. Thus, inflow of vehicles should always be discouraged to either increase or decrease flow of vehicles for economic efficiency. Moreover, even when optimal policy requires equilibrium flow to increase, the optimal flow itself must decrease
Structural patterns of land types and optimal allocation of land use in Qinling Mountains
in mountainous areas, namely, spatial, quantitative and qualitative structures of mountainous land types. After the all-around comparative analysis, an optimal allocation of land use in Qinling Mountains has been put forward according to the principle
