河北省旱灾情况及成因

The Situation and Cause of Drought in Hebei Province

通过对河北省旱灾情况及其成因的分析,表明河北省旱灾成因主要是因为降水量少而不均匀,降水变率大,生态恶化,水资源贫乏,农田水利设施建设滞后。河北水资源严重短缺是长期生态破坏的恶果,主要由于山区森林植被破坏和平原湖泊沼泽消亡。中古时代的河北水资源丰富,水稻种植规模可观。要加大资金投入,大力实施退耕还林、还牧,恢复和改善黄土高原生态环境;要加快设施和技术改造,推广实施节水灌溉技术。

Through analyzing the situation and cause of drought in Hebei Province,it showed that the main reasons of drought in Hebei Province were the small amount and unevenness of precipitation,the instability of precipitation,deterioration of ecology,shortage of water resources and the lag of water conservancy facilities.The serious shortage of water resources was the disastrous result of long time’s ecological destruction which mainly included the destruction of forest vegetation cover in mountains and the extinction of plain lakes and swamps.In Middle Age,the water resources in Hebei Province were abundant where the scale of rice cultivation was considerable.The situational change of drought in Hebei warned us to enlarge the capital investment,we should greatly carry out the campaign to restore the farmland to forests and pastures,restore and improve the ecological environment of Loess Plateau,fasten the pace of facility and technological reconstruction and popularize as well as enforce the water saving irrigation technology.
