| 摘 要： | 通过现场调查、盆栽试验和采样分析的方法，研究了用草浆废水灌溉海涂芦苇湿地对土壤理化性质、微生物数量和芦苇生长的影响。结果表明，灌溉后土壤中的有机质、N和P含量有所增加，土壤盐份含量明显下降，同时土壤中的细菌、放线菌和霉菌的均大幅度增加。一定质量浓度的造纸废水灌溉对湿地芦苇的生长有促进用、对土壤的性质有改良作用，但废水质量浓度过高则对土壤的理化性有不利影响。本文推荐造纸废水灌溉海涂芦苇湿地的适宜质量浓度为1000mg／L以下。 |

| Abstract: | Through field investigation, pot experiment and sample analysis, effects on the soils, animalcules and reeds in seashore wetland irrigated by pulp wastewater were studied in this paper. Results showed that the amount of organic matter,nitrogen and phosphorus in the soils were increased, and also the salt proportion was decreased. Contemporary, experiment exhibited a distinct increase in bacteria, actinomycetes and fungi after the soils were irrigated. It did well to the soils and reeds irrigated by pulp wastewater, but there had some side-effect if the concentration was too high, and the feasible concentration of wastewater for irrigating on reeds wetlands was below 1 000 mg/L. |
| Keywords: | Pulp wastewater wetland soil reeds animalcule |
