The widespread depravation of the global water environment has caused pollutions and safe problems of drinking water resources, especially in big cities.

In this paper,a model system and new algorithm are developed for the coordinative management of water resources utilization and regional economic development, according to the theory of the hierarchical optimal control on a large-scale system.

In this paper, a multilevel hierarchical optimal model and a new algorithm are developed for the coordinative management of water resources utilization and regional economic development, according to the theory of the hierarchical optimal control on a large-scale system.

Present situation and countermeasure of water resources development in Yangling;

And the response of runoff to water resources development(extraction for use) is estimated quantitatively based on the comparison between the observed and natural runoff data of Taonan hydrological station during 1961-2000.

Based on the introduction of exploitation and utilization of water resources in Geermu-Nuomuhong region, the environmental macro-effects caused by the exploitation of future water resources are discussed with the quantity equilibrium method, aiming at the environmental problems in the exploitation and utilization of water resources before.

Therefore,it is neccessary to strengthen the study on water resource,analyze the potentiality in depth,which is of great importance to water resources optimization management and the fully development and utilization of water resources in Henan Yellow River Water Irrigation District.
