| 摘 要： | 对海河流域平原地区在灌溉条件下N、P形态转化和淋失进行了研究.结果表明,平原地区在灌溉条件下,干湿交替的土壤中将产生硝酸盐及少量亚硝酸盐,这些产物将随灌溉水一起向心土层渗漏,逐渐脱离生物循环进入地质大循环,造成地下水污染.

| Abstract: | The N,P form conversion and leaching under the condition of irrigation in the plain area of Haihe River basin were investigated. The results show that more nitrate and less nitrite have been produced in this area when the soil is under the conditions of wet and dry alternations. These products will be leached with the irrigation water into the subsoil and gradually leave biological cycle and enter the geological cycle and causing the groundwater pollution. |
