By solving management model, the optimal groundwater withdrawal 〓 of the Wuwei Basin in two irrigation periods are obtained,〓 shows that the pumping condition of groundwater in the region can divided into six sub-regions: the pumping sub-region with maximum 〓 is located in the river courses; the sub-region with minimum 〓 in the spring overflow zone; and non-pumping sub-region in the 〓 irrigated districts and desert area, and that the unique way to crese groundwater pumpage is to pirate evapotranspiration in the oundwater evaporation zone.

通过管理模型的运转，获得了武威盆地平水年、枯水年、丰水年三个典型年份各灌期地下水的最优开采方案。按年最优开采模数，区域地下水的开采条件可分为六个区，地下水最强的开采区位于出山河流的主河道、石羊大河和洪水河沿岸，最弱的地区为泉水溢出带，河水谨区和沙漠区下开采地下水。同时表明，袭夺潜水蒸发量可增加地下水的开采量，该区现状条件下增加地下水的开采量的唯一途径是袭夺潜水蒸发带地下水蒸发量。

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.

在流域输沙量动态模型的建立中，由于研究时段长、研究流域尺度大，对输沙量各影响因子进行全流域逐年动态监测十分困难，考虑输沙量的年际变化主要受降雨-径流水文条件和水土保持措施等土地管理活动的影响，首次提出与地表径流模数和治理时间相关的综合影响因子，并通过因次分析法和二元非线型回归法确定了具体的表达式。
