基于三维生态足迹的2000年~2014年石河子生态安全评价

Ecological Security Assessment of Shihezi from 2000 to 2014Based on Three Dimensional Ecological Footprint

利用生态足迹分析方式,对石河子2000年~2014年的生态足迹、生态承载力、生态赤字和生态压力进行计算和动态分析研究。其结果表明:人均生态足迹由2000年的2.388216 hm2增加到2014年的6.049847 hm2,增加速度为0.244109hm2/年,增加幅度为60.52%。人均生态赤字由2000年的-0.72892 hm2增加到2014年的-4.47925 hm2,增加速度-0.250022hm2/年,增加幅度为83.73%。这表明生态足迹需求高度大于生态足迹供给,当前的生态系统处于极不安全状态,发展模式也是不可持续的,且不可持续性较强。说明石河子在城市化进程加快在带来经济效益同时,也加剧了人地矛盾,严重破坏了生态环境。研究最后结合本地区特点提出了一些科学合理的对策。

In this study,the ecological footprint,ecological carrying capacity,ecological deficit and ecological pressureof Shihezi from2000to2014were calculated and analyzed by means of ecological footprint analysis.The resultsshowed that:the per capita ecological footprint increased from2.388216hm2in2000to6.049847hm2in2014,with anincrease rate of0.244109hm2/years,with an increase of60.52%in the range of.Per capita ecological deficit increasedfrom-0.72892hm2in2000to-4.47925hm2in2014,an increase rate of-0.250022hm2/years,an increase of83.73%.This shows that the ecological footprint demand is higher than the ecological footprint supply,the current ecosystem isin a state of extreme insecurity,the development model is not sustainable,and the degree of sustainability is growing.This shows that the acceleration of urbanization in Shihezi has brought economic benefits,but also exacerbated the contradictionbetween man and land,seriously damaged the ecological environment.Finally,some scientific and reasonablecountermeasures are put forward according to the local characteristics.
