基于生态足迹的齐齐哈尔市土地承载力研究

以齐齐哈尔市为研究区,基于生态足迹理论,运用生态足迹方法,修正耕地和建设用地产量因子,对齐齐哈尔市2001-2012年生态足迹、生态承载力和生态赤字/盈余进行定量计算和分析。结果表明,①齐齐哈尔市耕地和建设用地产量因子均为1.78,人均生态足迹增长幅度较大,生态足迹呈上升趋势,土地生态足迹需求量大幅提高;②区域土地承载力略有增加,增加幅度较小,土地所能提供的生物生产面积有限,增长潜力不大;③区域土地生态安全度下降,生态压力指数大幅增加,出现严重生态赤字,且生态赤字不断扩大。结果显示,齐齐哈尔市生态环境已处于不安全状态,可持续发展受到威胁,应走集约化工业道路,采用严格控制耕地质量以及提高人口素质...

Summary:以齐齐哈尔市为研究区,基于生态足迹理论,运用生态足迹方法,修正耕地和建设用地产量因子,对齐齐哈尔市2001-2012年生态足迹、生态承载力和生态赤字/盈余进行定量计算和分析。结果表明,①齐齐哈尔市耕地和建设用地产量因子均为1.78,人均生态足迹增长幅度较大,生态足迹呈上升趋势,土地生态足迹需求量大幅提高;②区域土地承载力略有增加,增加幅度较小,土地所能提供的生物生产面积有限,增长潜力不大;③区域土地生态安全度下降,生态压力指数大幅增加,出现严重生态赤字,且生态赤字不断扩大。结果显示,齐齐哈尔市生态环境已处于不安全状态,可持续发展受到威胁,应走集约化工业道路,采用严格控制耕地质量以及提高人口素质等对策,改变齐齐哈尔市土地利用不合理现状。

Qiqihar is in the study area, based on the theory of ecological footprint and use the ecological footprint method, correction the farmland and construction land yield's factor, quantitative calculation and analysis the Qiqihar 2001-2012 ecological footprint, ecological capacity and ecological deficit/surplus. The results showed that, ① Qiqihar farmland and construction land yield factors were 1.78, the growth rate of per capita ecological footprint was larger, and the ecological footprint on the rise, a substantial increase in the demand for human ecological footprint on the land; ② Regional land carrying capacity increased slightly, but it increased to a lesser extent, the land can provide biological pro
