赣州市2012~2016年生态安全评价

Ecological Safety Evaluation of Ganzhou City from 2012 to 2016

以江西省赣州市为主要研究对象,本文主要根据2012~2016年江西省统计年鉴数据、运用生态足迹模型对当地生态安全进行定量研究,评价赣州市的生态安全情况,以分析该市可持续发展潜力。结果表明:赣州市2012~2016年间人均生态足迹和人均生态承载力变化整体呈现上升趋势,人均生态足迹从2012年的0.997 hm2增加到2016年的1.188 hm2。2012~2016年间赣州市一直处于生态赤字状态,生态压力指数均大于0.8,处于不安全状态,该市2012年生态情况表现为较不安全,2013~2016年期间更是处于极不安全状态。表明该市生态压力较大,经济发展处于不可持续状态,自然生态与社会经济发展的协调性有所下降,结合赣州市的实际情况,提出了相应的建议与措施。

Taking Ganzhou City Jiangxi Province as the main research object, this paper applied the ecological footprint model to quantitatively study the local ecological security based on statistical yearbook data of Jiangxi Province from 2012 to 2016. Meanwhile, the condition of ecological security was evaluated to analyze the potential sustainability of Ganzhou City. The results showed that changes in per capita ecological footprint and per capita ecological carrying capacity of Ganzhou from 2012 to 2016 indicated an overall upward trend. More specifically, per capita ecological footprint increased from 0.997 hm2 in 2012 to 1.188 hm2 in 2016. Ganzhou City had got an ecological deficit from 2012 to 2016 with its ecological stress indexes greater than 0.8, which was an unsafe state. The city’s ecological condition was relatively unstable in 2012 while it turned extremely unsafe from 2013 to 2016. It indicated that the coordination between natural ecology and socio-economic development in Ganzhou declined, and the city had intense ecological pressure as its economic development was unsustainable. Combining the actual situation of Ganzhou City, corresponding suggestions and measures were put forward.
