摘要
测算1994年-2015年日照市生态足迹及生态承载力,剖析日照市可持续发展状况;从人口规模、经济发展和科技水平三方面选取10个生态足迹影响因子,使用偏最小二乘法分析日照市生态足迹影响因子的重要性。研究结果表明,日照市1994年-2015年人均生态足迹大致呈上升趋势,人均生态承载力数值与变化幅度均较小,表现为生态赤字;从各影响因子来看,城镇居民人均消费支出、第一产业产值、第二产业产值对生态足迹的影响显著,第三产业产值对生态足迹影响最小。
The ecological footprint and the ecological carrying capacity of Rizhao City were analyzed from 1994 to 2015.The sustainable development state of Rizhao City was evaluated.Ten ecological footprint-influencing factors were selected from the aspects of population size,economic development and technological level.Using partial least squares analyzed the importance of the influencing factors of ecological footprint of eco-city in Rizhao city.The results showed that the per capita ecological footprint of Rizhao city was increasing from 1994 to 2015.The value and varied range of per capita ecological carrying capacity were relatively small,which revealed the ecological deficit obviously.Among the ten ecological footprint-influencing factors,the output of primary industry,secondary industry had a significant impact on the ecological footprint,and output of tertiary industry had the least impact on the ecological footprint.
