楚雄市生态足迹的动态变化研究

Study on the Dynamic Change of Ecological Footprint in Chuxiong City

"生态足迹"作为一种生物物理量的定量测评方法,在全球范围内应用越来越广泛。本文在获取大量基础数据的基础上,计算了楚雄市1993—2007年的生态足迹。通过计算发现,楚雄市的人均生态足迹逐年上升,从1993年的0.68 hm2上升到2007年的1.02 hm2。其中,耕地生态足迹增长对人均生态足迹上升的贡献率最大。生态足迹的上升与GDP的增长有明显的相关关系(R=0.803),通过曲线拟合,发现二者CUB曲线拟合度最高,为0.829。

As a kind of quantitative assessment to biomes, Ecological Footprint method is used more and more widely in the global scope. On base of gain large amounts of data, the author calculated the ecological footprint from 1993 to 2007 of the city of Chuxiong. Through computation showed that the ecological footprint of Chuxiongpercapita is rising year by year, from 0.68 hm2 rise to hm2 1.02 in those years. Among them, the ecological footprint of cultivated land per capita growth on the contribution of the ecological footprint rise is the largest. The ecological footprint rises and GDP growth has obvious relationship （ R = 0.803）, through the curve fitting CUB curve fitting degree, found that the highest, for 0. 829.
