摘要: 石羊河流域位于甘肃省河西地区东部,大致在北纬37°07'-39°24',东经101°22'-104°04'之间。行政范围包括武威、古浪、民勤三县和金昌市的全部,天祝县的一部分,及肃南县的皇城区,山丹军马场的一部分。流域长300公里,流域面积41149平方公里。流域地势南高北低,自西南向东北倾斜,由南向北可分为四个地形区:①祁连山山地,②走廊平原,③北山山地,④阿拉善高原。

Abstract: Shiyang He River drains a basin of 41,149 Square Kilometers, in this basin the discharge of surface water is about 1,594,600,000m3, and the ground water amounts to 1,049,600,000m3.which mainly comes from the conversion of the stream whereas the recharge of underground flow, precipitaton and condensation water counts for little. The utilization of land today is somewhat irrational. According to the calculation of the balance between land and water resources,the exploita-t ion and utilization of water resources, the overused distinctly, thus causing a series of variation of environment and problems in production. From now on we must consider the river basin as a whole and make reasonable arrangements for the whole area the irrigated lands should be determined based on the quantity of water supply, when distributing the water within both the upper reaches and the lower reaches should be sure to use the water economically and take the road of increusing perunit area yield and create the highly effective artificial ecosystem.
