論文概要:Urbanization, as a dynamic process, has significantly influenced global population distribution, economic development, and environmental conditions. While it offers improved access to resources and services, rapid urbanization also brings critical environmental and ecological challenges, such as land degradation, loss of biodiversity, and urban heat island (UHI) effects. This study provides a comprehensive evaluation of the urbanization process and its eco-environmental impacts in China, focusing on urban sprawl and UHI phenomena.
Using remote sensing technologies and Geographic Information Systems (GIS), this research examines the spatial and temporal dynamics of urban expansion and its environmental consequences. The study employs maximum entropy and quadrant scatter analysis methods to assess urbanization and eco-environmental levels at the provincial scale. Furthermore, DMSP/OLS nighttime light data and Landsat imagery are utilized to measure urban dynamics and evaluate UHI effects in key metropolitan areas, including Beijing.
The findings highlight significant regional imbalances in urbanization and eco-environment development. While Eastern China demonstrates high urbanization levels, its eco-environmental indices indicate the need for improved sustainability measures. Conversely, regions in Northwest and Southwest China require accelerated urban development to achieve balanced growth. The analysis of UHI effects reveals a direct correlation between urbanization intensity and elevated surface temperatures, emphasizing the critical role of vegetation coverage and urban planning in mitigating thermal stress.
This study provides actionable insights into the interdependencies between urban growth and environmental sustainability. By proposing targeted strategies for eco-environmental enhancement and UHI mitigation, it contributes to the broader discourse on achieving sustainable urbanization. The research outcomes offer valuable guidance for policymakers and urban planners aiming to balance economic development with environmental conservation.
