| 中文摘要: |
| 借助高分遥感影像，通过目视解译手段提取红河流域内工业区、工厂、矿山、尾矿库和水产养殖场5类水环境污染源信息，并对中越境内污染源状况对比分析。结果表明，红河流域越南境内的工业区、水产养殖场数目均多于中国境内，而中国境内的矿山、尾矿库数目均多于越南境内，两国境内的工厂数目相当。此外，矿山和尾矿库主要分布在红河干流及一级支流附近，增加了红河重金属污染风险。 |
| 英文摘要: |
| Based on high resolution remote sensing images，the information of five water pollution sources，from industrial district，factory，mine，tailing reservoir and aquafarm in the Red River Basin，were derived by visual interpretation. Comparing these pollution sources in China Vietnam border，the number of industrial districts and aquafarm in the Red River Basin of Vietnam were much larger than that in China. However，there were much more mines and tailing reservoirs in China than that in Vietnam. The number of factories were the same in China as in Vietnam. In addition，most of the mines and tailing reservoirs located near the main and tributary stream of the Red River，which increased the risk of heavy metal pollution in that area. |
