摘要
水质适宜性是农田排水资源灌溉利用的前提,为探究河套灌区农田排水资源灌溉利用的可能性和模式,以河套灌区城关镇境内试验基地的农田排水为例,采用模糊数学评价法对排水水质适宜性进行评价,通过盐度、碱度、矿化度法以及综合危害系数法、灌溉系数法对模糊数学评价结果进行验证。结果表明,河套灌区夏灌期农田排水水质对灌溉利用较适宜,但有必要采取一定措施防止土壤发生盐碱化。
The suitability of water quality is the premise of irrigation of farmland drainage resources. In order to find out the possibility and mode of irrigation of farmland drainage resources in Hetao irrigation area, we took farmland drainage of test base in Chengguan Town as the research object. The suitability of water quality was evaluated by fuzzy mathematics, and the results were verified by methods of salinity, alkalinity and salinity, comprehensive hazard coefficient and irrigation coefficient. The results showed that the drainage quality of farmland in summer irrigation period was suitable for irrigation, but it was necessary to take some measures to prevent soil salinization.
