| 摘 要： | 我国是施肥施用量最大的国家,不合理的磷肥施用所造成的农业非点源污染已经对环境产生了严重的不良影响。本文主要是在GIS的技术支持下,利用磷指数法,对我国农用地非点源磷污染危险性进行评价。从计算结果来看,我国九大流域中,东南河流片和淮河流域为很高危险区域,珠江流域、长江流域、海河流域和西南河流片为高危险性区域,松辽河流域和黄河流域为中危险性区域,内陆河流片为低危险性区域。 |
| 关 键 词： | 农业非点源污染 磷指数法 GIS技术 评价 |

| Abstract: | A large amount of chemical fertilizers have been used in China.The unreasonable phosphorus fertilization has an adverse impact on the environment,particularly the agricultural non-point source pollution caused by agricultural nutrient loss.Under the GIS technical support and the reference on the widespread applied phosphorus index method.Then the target system was established and the phosphorus pollution risky indexes were calculated.The result indicated that the Southeast Rivers region and the Huaihe River... |
| Keywords: | agricultural non-point source pollution phosphorus index method the GIS technology appraisal |
