Net primary productivity (NPP) dynamics and associated urbanization driving forces in metropolitan areas: a case study in Beijing City, China

摘要: Context Eco-environmental effects of urbanization are a focus in landscape ecology. Objective The influences population, economic and spatial development during the process Beijing City, China on net primary productivity (NPP) were analyzed. responding mechanism NPP different stages was also examined to develop advice about ecoenvironmental sustainability urban development. Methods Using Carnegie Ames Stanford Approach model, we estimated NPP. linear regression polynomial analysis, analyzed responses urbanization. Results High areas located northeast Yanqing, northwest Miyun, northern Huairou Pinggu. distribution generally occurred following order from high low NPP: outer suburbs, inner encircled city center, city. Because heat island effect winter, center higher 2009 than 2001. There negative correlation between both urbanization, but an increase population did not necessarily lead immediate decrease An analysis dynamics five kinds zones showed that resulted lasting observable loss over time space, although there some promotion highly urbanized zones. Conclusion three response urbanization: damage stage, antagonistic coordination stage. stage threshold depends local eco-environmental management planning interventions.
