Spatio-temporal Analysis of Ecological Carrying Capacity in Coal Mining Cities based on RS and GIS

12135,2926,12136

This paper used remote sensing data and geographic information system (GIS) technique, as well as social and economy development index to improve the traditional ecological carrying capacity model in order to analyze the spatio-temporal dynamics of ecological carrying capacity. Results showed that the ecological carrying capacity per capita kept declining from 1985 to 2015. The declining trend became more obvious from 2000 to 2015. Social and economy development had an impact on the decline. As for the spatial distribution of ecological carrying capacity, the city showed a strong variability between regions with high capacity in urban center and low capacity in the surrounding county. The main ecological carrying capacity transfer types were crop land, forest, construction land and mining land. The obtained results also proved that the study of ecological carrying capacity can be used in future urban planning.
