Identifying critical riparian zones for eco-environmental management of the Yangtze River through pollution mapping.

Riparian zones, which are critical interfaces between terrestrial and aquatic ecosystems, are essential for biodiversity, water quality, and landscape stability but are increasingly threatened by anthropogenic activities. The Yangtze River is the longest river in Asia, the riparian zones of which are highly affected by humans, however, they are less studied in terms of pollution change and distribution, which hinders efficient eco-environmental management. This study explored land use and nitrogen and phosphorus non-point source pollution variations in the middle and lower Yangtze River riparian zones from 1995 to 2015 and identified critical risky segments as management priorities.

Evolutionary game analysis of indoor radon mitigation with local government involvement.

Radon is the second leading risk factor for lung cancer after smoking. As a public policy, radon mitigation not only involves radon control technology or its cost-benefit analysis, but also includes the decision-making process of local governments. In this study, the evolutionary game theory was used to analyse the interaction between local governments and residents based on the subsidy of the central government.
