摘 要:对赣东北地区 (进贤、东乡、临川、余江 )低丘红壤坡地浅层地下水位的周年变化规律、水质情况及旱季供水能力等进行了系统研究。研究结果表明 ,这一地区的浅层地下水位平均为 4.3 8m ,3~ 8月为高水位期 (平均水位 3 .42m) ,9月至次年 2月为低水位期 (平均水位 5.3 5m) ,水质呈酸性 ,硝态氮含量较高。降水量、地形、地质等因素对地下水位有十分明显的影响。旱季打井提水 ,只要井深达到贮水层 (砂卵石层 ) ,一般水量充足 ,可满足旱季果园灌溉需求。The author systematically studied the moveable regularity of shallow subsurface water in low hilly red soil region of northeast Jiangxi (Jinxian, Dongxiang,Linchuan and Yujiang), the results were as follows :the average water table level was 4.38m;the water level was high (3.42m) from March to August, and it was low (5.35m) from September to February of the next year; the subsurface water was acidic, and contained much NO\+ -N \-3; rainfall, elevation and soil texture had very obvious influence on the water table level; in dry season, the well whose bottom had reached to the aquifer (gravel-pebble stratum) generally had plenty of water for the irrigation of orchard.\;
