| 摘 要： | 运用40年降雨、蒸发、径流的同步资料,计算了西北地区的降水总量为7981.9×108m3,地表水资源总量为2164.8×108m3;地下水资源量为1034.6×108m3,扣除重复量后的水资源总量为2304.4×108m3。分析了水资源的地区分布及年内、年际变化规律,评价了西北地区水资源质量,并总结了西北内陆河区径流主要形成于山区,散失于山前平原盆地等水资源六大特点。

| Abstract: | By using40years synchronal data of rainfall,evaporation and runoff,the precipita-tion,surface water resources,groundwater resources and total water resources excluding duplica-tions in Northwest China are calculated.They are7981.9× ,2164.8×108m3 ,1034.6×108m3 and2304.4×108m3 ,respectively.Based on the analysis of spatio-temporal distribution of water re-sources,the quality of water resources in Northwest China is evaluated,at the same time,6par-ticularities of water resources in Northwest China are,summarized. |
