Influence of landscape structures on river water quality at multiple spatial scales: A case study of the Yuan river watershed, China

Qiyu Xu et al.

Summary: This study evaluated the influence of landscape structures on river water quality at different spatial scales, finding that the impact varied depending on the distance from the river. Joint effects between landscape composition and landscape configuration were found to contribute significantly to explaining water quality variation. The regional division method used also had a considerable impact on the measured correlation between landscape structures and water quality, with larger basin area divisions enhancing the correlation.

Cleaner agricultural production in drinking-water source areas for the control of non-point source pollution in China

Rongjia Wang et al.

Summary: With continuous population growth and urbanization in China, pollution in drinking-water source areas from domestic sewage, aquaculture waste, and agricultural activities has become a significant issue. Implementing cleaner agricultural practices and constructing pollution treatment facilities are essential for protecting the environment and water quality.

The river chief system and agricultural non-point source water pollution control in China

Zhou Li et al.

Summary: The river chief system has shown effectiveness in reducing agricultural non-point-source pollution, particularly in reducing the negative impact of manure output from animal breeding operations on surface water quality. However, it has been found to be ineffective in addressing water pollution caused by fertilizer use, indicating room for improvement in cooperation among river chiefs and efforts to prevent fertilizer loads from entering surface waters.

The response of the migration of non-point source pollution to land use change in a typical small watershed in a semi-urbanized area

Yao Qian et al.

Summary: The research focuses on the impact of land use change on the migration of non-point source (NPS) pollution in semi-urbanized areas. By proposing the land use impact coefficient (LUIC) and optimizing land use types, it is possible to reduce the export coefficient (EC) of NPS pollution. The closer to the mainstream of the river, the more effective the reduction of EC by optimizing land use in areas with high LUIC values.
