摘　　要：以宜春市为例,基于生态足迹模型分析了2000—2020年江西宜春市人均生态足迹、人均生态承载力,以及结合土地利用可持续性指数、万元GDP生态足迹、生态足迹多样性指数、生态经济系统发展能力指数、生态足迹指数,探索基于生态足迹模型的人口与经济承载规模预测。结果表明,宜春市人均生态足迹自2000年到2020年增加235%,而人均生态承载力增加不过174%,当下宜春市资源的需求量远超生态所能提供的供给量。2000年,宜春市生态发展状态处于接近平衡状态,但目前已处于生态不可持续发展状态,虽然宜春市的经济发展模式正在向可持续发展方向发生转变,但生态赤字总体仍存在逐步增大的趋势。为了缩小供求之间的缺口,着力提高宜春市的生态承载力是势在必行的。Taking YiChun city as an example,based on the ecological footprint model,the per capita ecological footprint,per capita ecological carrying capacity,including the sustainable index of land-use,GDP’s ecological footprint,ecological footprint diversity index,ecological economic system development capacity index,ecological footprint index of YiChun city from 2000 to 2020 were analyzed.The population and economic bearing scale prediction were explored based on the ecological footprint model.The results show that the per capita ecological footprint of YiChun city has increased 235% from 2000 to 2020,while the per capita ecological carrying capacity has increased only 174%.At present,the demand for resources in YiChun city far exceeds the quantity of ecological supply.In 2000,the state of ecological development was close to balance,but yiChun city has been in the state of ecological unsustainable development,although the economic development mode of YiChun city is changing to the direction of sustainable development,but the overall ecological deficit is still gradually increasing.In order to reduce the gap between supply and demand,it is imperative to improve the ecological carrying capacity of YiChun city.
