【摘要】：研究塔里木盆地生态赤字的动态变化,为政府部门合理规划塔里木盆地人与自然和谐发展提供依据,运用生态足迹和适度人口模型,计算了塔里木盆地2002-2010年的生态足迹、生态承载力和适度人口规模,并将其与现实人口进行对比分析。结果表明:2010年塔里木盆地人均生态资源需求明显大于人均生态资源供给,生态处于不可持续状态。动态来看,2002-2010年间,塔里木盆地适度人口规模与实际人口数反向变化,生态赤字呈扩大趋势,赤字人口从2002年的166.83万人大幅增加到2010年的569.26万人,人类对耕地、草地和化石能源用地的开发和利用超出了其生态承载力的阈值,塔里木盆地人口与资源环境协调性在下降。认为这是塔里木盆地人口增长、人均生态资源需求增加的反向影响,以及技术进步、资源利用效率提高的正向影响共同作用的结果。
[Abstract]:This paper studies the dynamic changes of ecological deficit in Tarim Basin, and provides a basis for government departments to plan the harmonious development of human and nature in Tarim Basin. The ecological footprint of Tarim Basin from 2002 to 2010 is calculated by using ecological footprint and appropriate population model.Ecological carrying capacity and appropriate population scale are compared with real population.The results show that the per capita demand for ecological resources in Tarim Basin is obviously larger than the per capita supply of ecological resources in 2010, and the ecology is in an unsustainable state.From 2002 to 2010, the moderate population scale in Tarim Basin changed inversely with the actual population, and the ecological deficit increased from 1.6683 million in 2002 to 5.6926 million in 2010.The exploitation and utilization of grassland and fossil energy land exceed the threshold of ecological carrying capacity, and the coordination between population and resource environment in Tarim Basin is decreasing.It is considered that this is the result of the negative effect of population growth, the increase of ecological resource demand per capita, as well as the positive effect of technological progress and resource utilization efficiency in Tarim Basin.
