随着农业生产的发展,农业用水量急剧增加,在许多地表水不足的地方,积极开采地下水发展水田。黑龙江省绥化地区近些年打井种稻面积就达91.3万宙。这些地区由于冬春季节地下水补给减少,到泡田灌溉期后,地下水可利用量明显降低,水的供需矛盾日渐突出。特别是有些地方盲目发展水田,过量开采地下水,不但造成降落漏斗,而且由于水源不足,种稻不成,造成很大的经济损失。笔者认为,对地下水资源必须合理开发和保护。一、强化管理限量开发要建立健全水政水资源管理体系。各级水利部门要切实转变职 With the development of agricultural production, the amount of water used in agriculture has risen sharply. In many places where surface water is not enough, groundwater is actively exploited to develop paddy fields. Suihua Prefecture in Heilongjiang Province in recent years, drilling up to 91.3 million rice area. Due to the reduction of groundwater recharge during the spring and winter in these areas, the availability of groundwater has been significantly reduced after the irrigation period of the soils, and the contradiction between supply and demand of water has become increasingly prominent. In particular, the blind development of paddy fields in some places and excessive exploitation of groundwater have not only led to the decline of funnels, but also caused great economic losses due to insufficient water resources and lack of rice. The author believes that groundwater resources must be properly developed and protected. First, to strengthen the management of limited development to establish and improve water and water management system. Water conservancy departments at all levels must effectively change their positions
