摘要
以白洋淀流域为研究区,基于生态足迹模型,结合统计年鉴数据、遥感影像数据,测算该流域2000年、2010年、2020年的生态足迹、生态承载力以及生态盈余(赤字)状况,并从时间和空间上分析其演化特征.结果表明,2000-2020年白洋淀流域整体以及大部分区县的人均生态足迹呈下降趋势,且具有南部高、西部低的格局;2000-2020年流域整体的人均生态承载力波动较小且存在空间分异,西北部人均生态承载力较高,中部、东南部人均生态承载力较低;2000-2020年流域整体处于生态赤字状态,但生态赤字水平在逐渐好转,西北地区生态盈余,中东部生态赤字,经济发展水平与生态盈余(赤字)紧密相连.
Abstract
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.
