| 中文摘要: |
| 随着全球环境恶化的速度加快,区域生态安全问题日益突出,特别是对高温伏旱区的生态安全的研究需求越来越迫切。本文利用基于能值理论改进的生态足迹模型,对重庆市江津区2002~2007年的生态安全现状做了全面评估。结果表明:(1)2002~2007年江津区均处于较安全等级,但是安全等级程度逐年下滑,因此需要密切关注;(2)在2002年之后,江津区一直处于强不可持续状态,程度呈逐渐加深的态势。 |
| 英文摘要: |
| With the accelerating pace of global environmental degradation, regional eco-security issues have become
increasingly prominent. As for the zone which has high temperature and drought in summer, the need of ecological secu-nity research is especially more and more pressing. Based on ecological footprint model improved by energy theory, a comprehensive assessment was made of the status of ecological security in 2002~2007 years of Jiangjin District in Chongqing city. The results showed that: (1) Ecological safety index of Jiangjin District was always in a relatively safe degree from 2002~2007, while the extent of security level was on the decline year by year, so it needs more attention from now on; (2) Ecological sustainability index of Jiangjin District has been in a strong non-sustainable degree since 2002, and the extent of the situation was gradually deepened. |
