【摘要】 通过三江平原4个具有代表性、典型性井灌稻农场的地下水动态分析有若干新发现:①从三江平原地下水动态分析,可进行地区农业用水量估算(与垂直补给为主者吻合)。若此推估量小于地区农业生态用水,说明有丰富的横向补给,有的可达雨养水稻有余;②即使4个典型区中开采强度大者地下水埋深在4~10 m,处于理想与允许埋深,具有抗灾、资源、环境生态水利功能,且尚有一定开采潜力。而全区平均地下水埋深虽约5 m,但开采强度偏小地区或地表灌区地下水埋深偏高,还应提高开采强度;③若三江平原全区开采强度达到4个典型区2006年开发利用水平,可发展以井灌稻为主的266.7×104hm2的宏伟规划;④从4个典型区现状分析,形成地下水库对于三江平原全区可达(200~400)×108m3的防洪除涝和多年调节地下库容,相当于全省总库容的2倍以上。可见三江平原开发利用地下水资源,除具有发展粮食生产,繁荣经济,且具有以上发现与功能。更多还原

【Abstract】 By dynamic analysis on groundwater of four represent and typical farm where well-irrigated rice has been developed very well,we get four points: ①By dynamic analysis on groundwater of Sanjiang Plain,we can make the valuation and calculation of agricultural water use.②Among four typical farms,even for the one whose groundwater was developed greatest,the buried depth is between 4-10 m and ideal.Which has functions of unti-disaster,resource and environment ecological conservancy? ③If the groundwater developing capacity of the whole Sanjiang Plain can get up to the level in 2006 of the four typical area,the great plan of developing 266.7×104 hm2 well-irrigating rice can be realized.④By enhancing the groundwater development,there will be a underground reservoir with(200-400)×108 m3 capacity formed in Sanjiang Plain.更多还原
