SPATIAL DISTRIBUTION AND FACTORS OF ECOLOGICAL FOOTPRINTS IN COAL RESOURCE-BASED CITIES
China's coal resource-based cities have been entrapped into plight due to their excessive mining activities,which can get resolved through studying the spatial distribution and path optimization of ecological footprints in coal resource-based cities.This paper,based on China's 35 coal resource-based cities,uses energy ecological footprint model and sustainability indicators to measure their energy ecological footprints,ecological deficit/remainder,ecological efficiency and ecological sustainability,and employs STIRPAT model to study their factors.Energy ecological footprints are closely related to energy consumption in coal resource-based cities,largely varying regionally,of which central to eastern China has the maximum energy ecological footprint.Most coal resource-based cities are loosing balance in ecological supply and demands,but their resources utilization efficiency can be gradually promoted under technical advances and supportive policies from perspective of ecological efficiency.Regression results of STIRPAT model shows a positive impact of economy and population on energy ecological footprints in coal resource-based cities,but negative from technical advances.This paper presents suggestions for coal resource-based cities in economic transformation and sustainable development.
