中文摘要:
      以宁夏集中连片特困区——西吉县为研究对象,基于特殊困难地区独特的生态系统特点构建其评价指标体系,采用生态承载力模型,对西吉县2007-2016年生态承载力能力进行评价研究。结果显示:研究期间西吉县生态弹性力指数和承载媒体的支撑力指数整体呈现出上升趋势,而其承载对象的压力指数在研究期间变化较为明显,整体上呈现出波动下降的趋势,由2007年的0.500 5下降至2016年的0.415 8。但总体看来,西吉县生态承载力指数呈现出上升趋势,生态系统的承载能力不断提高。
英文摘要:
      Taking Ningxia concentrated poor area, Xiji County, as the research object, based on the unique ecological system characteristics of special poor areas, constructed its evaluation index system, and using the ecological carrying capacity model, evaluated the ecological carrying capacity of Xiji County from 2007 to 2016. The results show that:during the period of study, the ecological elasticity index of Xiji County and the supporting index of supporting media showed an overall upward trend, while the pressure index of its carrying objects changed significantly during this period, and the fluctuation trend showed a downward trend as a whole, from 0.500 5 in 2007 to 0.415 8 in 2016. However, in general, the index of ecological carrying capacity of Xiji County showed a trend of upward change, and the carrying capacity of the ecosystem continues to increase.
