摘要
在灌溉期,粮食主产区农业生态受到灌溉水质的重大影响。聊城是山东省重要的粮食生产基地,选取灌溉河流--马颊河作为研究对象,布设5个监测断面,其中干流3个、支流2个,于春季灌溉期进行水质监测采样。采用单因子指数法进行水质评价,分析该时期潜在的农业生态安全隐患。研究结果表明,马颊河作为灌溉用水是可以达标的。通过分析,对农业生态安全影响不大。
In the period of irrigation, Water quality affects agro -ecological safety. Liaoeheng City is one of the most important food producing bases. Taking Majia River for example, five monitoring sections, of which the main stream of three, two tribu- taries, are carried out in the spring of irrigation water quality monitoring sampling. Through single - factor index of water quality evaluation, it is analyzed whether the period of the agro - ecological potential security risks. The results showed that ： surface water of Majia River will be safe to irrigate in the near future and the impact of the agro - ecological safety is not significant.
