Assessing cold exposure risk during cold waves in Beijing using high spatiotemporal resolution population data and temperature variations.

In the context of global warming, the frequency and intensity of extreme weather events are intensifying. Although cold waves have significant impacts on human health, related research remains insufficient. This study integrates high-resolution population dynamics and temperature data to assess cold exposure risks during cold waves in Beijing, addressing a critical research gap in urban public health.

Exploring the ecological security evaluation of water resources in the Yangtze River Basin under the background of ecological sustainable development.

The Yangtze River (hereafter referred to as the YZR), the largest river in China, is of paramount importance for ensuring water resource security. The Yangtze River Basin (hereafter referred to as the YRB) is one of the most densely populated areas in China, and complex human activities have a significant impact on the ecological security of water resources. Therefore, this paper employs theories related to ecological population evolution and the Driving Force-Pressure-State-Impact-Response (DPSIR) model to construct an indicator system for the ecological security of water resources in the YRB.
