China's rapid urbanization slightly decreased habitat quality (HQ). This study analyzed HQ and urbanization level (UL) changes across multiple scales, revealing spatial variations and negative impacts, crucial for targeted conservation policies.
Area of Science:
- Ecology
- Environmental Science
- Urban Planning
Background:
- China's unprecedented urbanization presents challenges for sustainable development.
- Existing research on development-conservation links lacks spatial analysis, hindering effective policy.
- Understanding the spatial relationship between urbanization and habitat quality is critical.
Purpose of the Study:
- To quantify habitat quality (HQ) and urbanization level (UL) changes in China from 2000-2020.
- To investigate the multi-scale spatial response of HQ to UL.
- To provide a scientific basis for ecological policy formulation.
Main Methods:
- Multi-source data utilized to measure HQ and UL in 2000, 2010, and 2020.
- Spatial regression and geographically weighted regression employed to analyze relationships.
- Multi-scale analysis of HQ response to UL and landscape patterns.
Main Results:
- A slight decline in overall HQ observed between 2000 and 2020.
- Hot spots of HQ change concentrated in central-western transition zones; cold spots in fragile/urbanizing areas.
- UL negatively impacted HQ across most regions, with decreasing intensity over time; landscape pattern effects varied by scale.
Conclusions:
- Urbanization significantly impacts habitat quality, necessitating spatially explicit conservation strategies.
- The scale-dependent nature of these impacts requires tailored environmental protection policies.
- Findings support evidence-based policymaking for balancing development and ecological conservation in China.

Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
