| Abstract: |
| Nonpoint source pollution（NPS）has emerged as a significant factor affecting securities of water resource and water environment, and thus NPS studies attracted much attention and concerns domestically and internationally. That is why it becomes one of the most challenging research fields in earth and environment science. The scientific and efficient management of NPS has been incorporated into national strategic plans. To ensure the sustainability of the water environment, therefore, promoting NPS research and control under the new circumstances and policies has become an urgent task. This study comprehensively reviews and summarizes the current status of NPS research, outlining primary methods and typical remediation measures. In light of the major issues identified in this study and the current situation of water pollution control in China, corresponding recommendations are provided, along with some constructive suggestions. This study can be valuable and informative for the comprehensive supervision, assessment, and management of NPS, contributing to the enhancement of China′s water pollution control systems. |
