| 摘 要： | 采用生态足迹理论，对南阳市的生态可持续发展状况进行了定量评估，计算结果表明：南阳市2005年人均生态足迹为0．9921hm^2，人均生态承载力为0．4946hm^2，人均生态赤字为0．4976hm^2，说明南阳市的发展正处于一种不可持续状态，人类对自然的利用程度已经超过了本地区自然生态系统所能承载的能力。南阳是南水北调中线工程水源地和渠首所在地，虽然水源地丹江口水库和渠首地的生态环境很好，但若水源地和渠首所在地南阳这一大环境的生态可持续发展不能实现，这势必会影响到中线工程的质量和长期效益的发挥。对此应予以关注。

| Abstract: | Using the ecological footprint theory,the ecological sustainable situation of Nanyang in 2005 is calculated and analyzed.The results show that the ecological footprint is 0.9921hm2 per capita,the ecological capacity is 0.4946hm2 per capita,the ecological deficit is 0.4976hm2 per capita.It shows that Nangyang is in an unsustainable situation,the utilization degree of human has exceeded the natural carrying capacity of this area's ecological system.Nanyang is the location of water source area of middle route ... |
