Short Summary

This study quantifies the impact of urban areas on vapor pressure deficit (VPD) in neighboring rural regions across China, revealing that 69% of cities exhibit significantly faster atmospheric drying in their adjacent rural areas compared to remote rural stations, primarily driven by urban-rural temperature gradients.

Objective

• To quantify urban impacts on vapor pressure deficit (VPD) in neighboring rural areas across China.

Study Configuration

• Spatial Scale: National scale across China, focusing on neighboring rural areas (NRS) surrounding cities and remote rural stations (RRS) far from urban influence, including analysis within urban clusters.
• Temporal Scale: 35 years (1985–2019).

Methodology and Data

• Models used: Statistical comparison of observational data.
• Data sources: Station observations from neighboring rural stations (NRS) and remote rural stations (RRS).

Main Results

• During 1985–2019, 69% of cities showed faster VPD growth in their neighboring rural stations (NRS) than in their remote rural stations (RRS).
• The mean drying rate in NRS was 27.5% higher than that of RRS.
• This disparity in drying rates was more pronounced during summer, especially within urban clusters.
• The temperature difference between NRS and RRS dominated VPD variations, attributed to the urban-rural temperature gradient where temperatures gradually decline outward from urban cores.

Contributions

• Reveals a potential and significant urban influence on atmospheric drying in neighboring rural areas.
• Highlights previously underappreciated ecosystem risks in these critical neighboring rural areas.
• Emphasizes the need for targeted adaptation strategies in sustainable urban development planning.
