The article discusses habitat quality in urban environments, particularly in relation to rapid urbanization in Suzhou, China, a key city in the Yangtze River Delta. It defines habitat quality as crucial for sustaining biodiversity and ecosystem stability, emphasizing the adverse effects of urban land expansion, which leads to habitat fragmentation and declines in biodiversity. Early assessments used static models based on field studies, but advancements in information technology have allowed for more dynamic and multiscale approaches, such as the InVEST model, which evaluates ecosystem services.
The research utilizes land use data from 2000, 2010, and 2020, employing the CA-Markov model to simulate future land use changes and the InVEST model to assess habitat quality changes. Findings reveal a general decline in habitat quality from 2000 to 2020, with predictions indicating continued deterioration by 2030 due to ongoing urban expansion. The study employs spatial autocorrelation to analyze habitat quality distribution, revealing significant low-quality areas primarily in urban centers and construction zones.
Factors influencing habitat quality include socioeconomic aspects, land use patterns, and environmental conditions, with the study suggesting strategies for habitat conservation, such as improving land use management and protecting vital ecological zones. The limitations of the research point to a need for more comprehensive analyses of socioeconomic impacts and external policies on habitat quality.
Key findings highlight the critical need to balance urban development with ecological sustainability to preserve habitats amidst ongoing urbanization. The comprehensive assessment models developed could aid decision-makers in managing urban land use effectively and ensuring the conservation of valuable ecosystems.
