| 摘 要： | 针对规模化畜禽养殖业发达地区畜禽粪便引发的重金属和可溶性盐污染负荷重等问题,以杭州市为例,分析了杭州市各区县由畜禽粪便引起的氮、磷污染负荷.同时,通过空间分析与基于土壤盐分和重金属累积模型的模拟预警分析,评估了畜禽粪便农用过程中对温室土壤次生盐渍化和重金属累积的潜在影响.结果表明,杭州市畜禽粪便氮磷污染负荷分布不均,以...

| Abstract: | Heavy metals and salinization resulted from intensive livestock production have been significant environmental problems in breeding developed areas.Livestock manure-derived nitrogen and phosphorus loads in farmland of districts in Hangzhou were calculated respectively in this study.The main heavy metals and salt content in livestock manure samples were analyzed and the potential risk was evaluated by the methods of simulating prediction on the accumulation model of salt and heavy metal in soil.As a result,t... |
