| 摘 要： | 为有效控制黑河流域非点源污染,改善黑河水库水质,按照行政区将黑河流域划分为9个地域单元。通过专家评判模式估算出了各行政单元的土壤侵蚀量。利用吸附态氮磷污染估算模型估算出了污染物流失量和吸附态氮磷污染负荷。结果表明,厚畛子乡、陈河乡、甘峪湾乡以及马召乡4村是非点源污染控制的关键源区。退耕还林、减少耕地、增加植被覆盖度、合理利用土地是控制土壤侵蚀型非点源污染的有效措施。 |

| Abstract: | To control effectively non-point pollution of the Heihe basin and improve water quality of Heihe river basin,the basin was partitioned to nine zones based on basin district.The expert judgment model was adopted to estimate the soil erosion intensity,and the absorbed nitrogen and phosphorus estimating model were used to estimate absorbed nitrogen and phosphorus loads.Houzhenzi county,Chenhe county,Ganyuwan county and four village of Mazhao county are the key regions of non-point source pollution control.Returning farmland for forestry and pasture,decreasing tillage land,increasing vegetation cover ratio and rationally land use plan would be the effective measures of controlling absorbed nitrogen and phosphorus pollution. |
| Keywords: | soil and water loss type non-point source pollution estimating Heihe watershed |
