摘要

Shiyang River basin is a special inland river basin in China, of which the population density is the biggest, per capital GDP is higher and the average per person water resources possession is the least. As a result, the contradiction between supply and demand of water resources is prominent, and the ecological environment deteriorates seriously in this region. Moreover the urbanized advancement development also gave Shiyang River water resources and the ecological environment research the new challenge. This paper shows that the basin water resources has already been seriously overloaded, and the basin comprehensive governing program ought to be urgent, through analyzing the present water supply volume, ground water equilibrium, the present water consumption level, the water used efficiency and the present supply and demand balance of Shiyang River basin. The prominent question of this basin is the scarce water resources, the contradiction of supply and demand, the suddenly dropping groundwater table, the intensifying of ecological environment degraded trend, degeneration of the Qilian Mountainous area ecology, the weakness of water source self-control function, the irrationality of economic structure, low efficiency of the water used, the distemperedness of the management system, the weak water resources unification management. After analyzing the origin of these questions, It is suggested advancing water saving, establishing saving water society, adjusting economic structure reasonably, optimizing disposition of water resources, developing the ecology construction vigorously, improving the ecological environment diligently, actualizing water resources unification management and attemper, enlarging water pollution preventing and controlling, enhancing the water environment quality unceasingly. By countermeasures to reserve source in south part of basin, develop oasis of middle part, control north part sandstorm, with the measure of protecting upper river, reforming middle river, rescuing down stream to prevent the trends of ecological environment degrading, improving the efficiency of water resources utilization, realizing integrate administration and sustainable utilization of water resources of basin, it will support the sustainable development of society, promote harmonic relationship between human and nature.
