目前，在灌溉回归水的水质预测方面缺乏相关的模型和计算公式。文章以海南省某灌区为例，首先采用类比分析得到了灌区灌溉回归水水量，然后结合灌区当地气候、水文特征，借鉴土壤中养分流失公式，采用化肥中养分流失公式计算灌溉回归水中总氮和总磷浓度。通过与当地调查研究专题结果对比分析，文章的计算结果与之差别很小。文章采用的计算方法可行，计算结果较为真实的反映了灌溉回归水的水质。

At present , the quality of irrigation return flow forecasted the lack of models and relevant calculation formula.Taking Hainan someone irrigation area as an example , the quantity of irrigation return flow was obtained by analogy analysis , and combining with climate , hydrological characteristics of irrigation , using the formula of soil nutrient loss, the quality of irrigation return flow was calculated by the fertilizer nutrient loss formula.By comparison with the results in the locality , the difference between the results was very small.The computation methods of this text was feasible and the results reflected the quality of irrigation return flow.
