黑龙江省江川灌区灌溉水资源的综合评价

在介绍江川灌区流域概况的基础上，提出了该灌区所面临的地下水灌溉水稻米质差、产量低、大米销路不好等问题的解决办法，即发展地表水灌溉水稻，通过引松花江水来解决灌溉水源；分别对地下水、地表水(松花江水)的水量和水质进行评价。结果表明，该灌区的地下水严重超采、水质中总铁量超标(超6mg/L)，pH值偏碱，不适合用于农业灌溉；地表水(松花江水)除铁离子略高外，其余各项指标均满足灌溉要求，为该灌区引松花江水灌溉水稻提供了较为科学的依据。

Comprehensive Evaluation on Watering Resource of Jiangchuan Watering Area in Heilongjiang Province

On the basis of introducing Jiangchuan river basin of watering area, made suggestions for bad quality of rice. low production, poor sale by underground water watering in this area. That is developing ground surface water to water rice by drawing Songhua river. Evaluated on the volume and quality of underground water, ground water(Songhua River).The result was that underground water was extracted too was alkalinity which wasnt fit for agricultural irrigation; various indexes of ground water was satisfied with irrigation except for a little high ironions. This provided scientific foundation for drawing Songhua River to water rice in this watering erea.
