摘要
运用生态足迹模型,对湖北省1985—2004年的生态足迹进行了时间序列的测度。结果表明:20年间,湖北省人均生态足迹需求均大于其人均生态承载力;比较其同时段不同尺度范围的生态赤字/盈余时发现,湖北省生态足迹在省与国家尺度上处于不可持续发展状态,而在全球尺度上处于可持续发展状态。在各种土地类型中,人均耕地生态赤字最大,人均林地处于生态盈余状态,且人均生态足迹需求增长最快的是水域,人均生态承载能力增长最快的是林地;总体上看,湖北省的人均生态足迹和人均GDP持续增长,而万元GDP的生态足迹一直呈现下降趋势;控制建设规模、保护耕地、增加新技术投入量是解决湖北省人均生态赤字过高的重要途径。
By using ecological footprint model, the ecological footprints in Hubei Province from 1985 to 2004 were measured in temporal sequence. The results showed that from 1985 to 2004, the per capita demand of ecological footprint in Hubei Province surpassed the per capita ecological capacity. The comparison of different scale ecological deficits/surplus in the same periods of time indicated that on provincial and national scales, the ecological footprints in Hubei Province were not in a sustainable development status; but on global scale, they were in a sustainable one. Among all kinds of land types in Hubei Province, farmland had the highest ecological deficit per capita, while forestland was in surplus. Water area had the fastest increasing speed in the demand of per capita ecological footprint, while forestland had the fastest one in the demand of per capita ecological capacity. Overall, the per capita ecological footprint and per capita GDP in Hubei Province kept increasing, while the ecological footprint of ten thousand Yuan GDP presented a downward trend. To control the scale of construction, protect the farmland, and increase the input of new technologies would be the important measures to solve the problems in ecological footprints in this province.
