江西省产业生态足迹变化研究

Study on Industrial Ecological Footprint Change in Jiangxi Province

利用生态足迹模型对1996～2004年江西省的生态足迹进行了计算,结果表明:江西省人均生态足迹由1.4083hm2增至1.6406hm2,其中耕地、草地比重在减少,其余在增加;按三次产业对生态足迹进行产业分解,其中第一产业对生态资源的占用比例最高,但增长速度最慢,资源利用效益最差;第三产业生态足迹量增长速度最快,效益最好;第二产业则介于第一、三产业之间;从第一产业中农林牧渔业生态足迹看,农业、牧业生态足迹呈减少态势,林业、渔业呈增长趋势,林业资源利用效益最好,其次是牧业和农业,渔业最差。

Ecological footprint of Jiangxi Province from 1996 to 2004 was calculated using the model of ecological footprint. The results showed： ①eeologieal footprint per capita of Jiangxi Province increased from 1.408 3 hm^2 to 1.640 6 hm^2, among which the proportions of cultivated land and grassplot reduced and others improved; ② decomposing ecological footprint into sectors, the occupancy percentage of first industry was tiptop, but its increment speed was the slowest and utilization benefit was the worst; ecological footprint of third industry increased quickest and the benefit was the best; second industry was between the first and third industry; ③ the ecological footprints of agriculture and animal husbandry were reducing, while those of forestry and fishery were increasing, and the resources utilization benefit of forestry was the best, animal husbandry, agriculture and fishery in turn.
