Evaluation and spatial-temporal pattern of ecological carrying capacity in Baiyangdian Basin based on ecological footprint model
Taking Baiyangdian Basin as the research area,based on the ecological footprint model,combined with statistical yearbook data and remote sensing image data,the ecological footprint,ecological carrying capacity and ecological surplus(deficit)of the basin in 2000,2010 and 2020 were estimated,and their evolution characteristics were analyzed from time and space.The results showed that,from 2000 to 2020,the ecological footprint of Baiyangdian Basin as a whole and most districts and counties showed a downward trend,with a pattern of high in the south and low in the west.From 2000 to 2020,the ecological carrying capacity of the basin as a whole fluctuated little and had spatial differentiation.The per capita ecological carrying capacity in northwestern areas was relatively high,while the per capita ecological carrying capacity in central and southeastern areas was relatively low.From 2000 to 2020,the whole basin was in a state of ecological deficit,but the level of ecological deficit was gradually improving.The ecological surplus in northwest China and the ecological deficit in central and eastern China were closely related to the economic development level.
