Multi-Dimensional Critical Control of Water Resource in Bayannur

Water resources system is characterized by complex interdependent components with multi-dimensional objectives. In this paper, multi-dimensional critical control of water resources is analyzed. Some indexes are used to set objective for each dimension and a model for multi-dimensional critical control is established. The case of Bayannur is studied as an example: the model is solved to derive Bayannur's initial water allocation for different aspects in the target year 2020. The relationships between economic benefits and per capita food consumption, the amount of over exploitation of groundwater, and the sewage emission are analyzed based on this model to obtain the relationship curves between the economic dimension and social, environmental, and ecological dimensions. The balance of regional water resources will be a constraint to impact water allocation. Finally, the objections and constraints are applied to the model based on the relationship curves and the balance of regional water resources. Under three demands, three best water use plan is proposed. This study provides a strong basis for planning and allocating water use in Bayannur.
