Theory And Practice On Efficient Utilization And Protection Pattern Of Water And Soil Resources In Typical Arid Area

One of the most basic principle of efficient utilization of water and soil resources is acts as circumstances permit, to the region the way of using the water and soil resources, use the scientific research theory instruction, according with the analysis of the target area's situation and make the concrete plan after research, proposed practical feasible innovation measure for the local water and soil resources efficient utilization and sustainable use, this is theory significance and the practice value on the t highly effective utilization of water and soil resources research, achieve the region sustainable development.This article take the land utilization planning, the water resource management, the conservation of water and soil, the sustainable development theory as the instruction, determines the nature of unifies with the quota method, analyze the Qira County water and soil resources characteristic and the present utilization, calculating the balance of water supply and requirement, making the optimized matching of water and soil resources, take the way of water and soil resources of efficient utilization and protection. The paper obtains the following conclusion:1. The Qira water and soil resources use is unbalanced, conducts the water and soil resources efficient utilization is the inevitably request of Qira water and soil resources sustainable use and the social economy sustainable development.2. Enhances the farmland irrigation coefficient of utilization is the prerequisites to achieve the Qira water and soil resources balance. Under the circumstances of the effective irrigation area should not be reduced, life, industrial, forestry and animal husbandry and fishery ecological water can only increase but not be appropriated, irrigation water affected by the water carrying capacity and the level of economic development restrictions, through improving water and water-saving irrigation is the inevitable choice for water and soil balance in Qira.3. Through the balance of water supply and requirement calculate and the present situation supply and demand forecast, with the character of each region, raised the different way of water and soil use to each region.4. Adjust the resources development intensity, make Value of resources and order the resource developments are the strategic focus of efficient utilization of water and soil resources. Strengthen the hydraulic engineering construction, develop the saving water of agriculture is the effective action of water and soil resources highly effective use and the protection in Qira.
