摘要
针对目前我国水资源紧缺、用大量污水进行农田灌溉造成环境污染的现状,指出了污水灌溉风险研究中的不足。利用农业干旱模型,通过非参数检验对污水灌溉风险的概率分布进行了研究,并利用江苏省南京地区某污灌区的实际资料,计算了当地污水灌溉风险的概率分布。
In the light of the present status of water resources shortage in China and environmental pollution caused by using a lot of sewage to irrigate cropland, the paper points out the shortage existing in the research on sewage irrigation risks. Based on the model of agricultural drought, the probability distribution of sewage irrigation risks is studied with nonparametric test, and the probability distribution of local sewage irrigation risks is calculated by using the actual data of sewage irrigation area of Nanjing city, Jiangsu province.
