| 摘 要： | 近年来,由于受人类活动的影响,地表与地下产水的下垫面条件发生了变化,造成水资源量、可利用量等水资源情势发生了变化,为此采用统计分析方法对宁夏各水资源分区1956—2000年径流系列进行了分析和预测.通过分析认为,宁夏年径流量周期性变化不明显,在总的趋势上宁夏今后一段时间内径流将处于偏枯阶段.

| Abstract: | Owing to impact of human activities in recent years,underlying surface conditions of surface and underground water production have changed.This caused amount of water resources and available water resources change.Based on the statistical analysis of 1956-2000 runoff series in different regions in Ningxia,this paper presented the wet and dry fluctuation and the general changing tendency of water resources in Ningxia.The conclusion is that the change of annual runoff has no obvious cycle,and the runoff will be in a dry stage in the coming period in Ningxia. |
