快速城市化进程中河南省域生态安全动态评价
The Dynamic Evaluation of Ecological Security during the Process of Rapid Urbanization in Henan Province
摘要
Abstract
Based on the ecological footprint theory, this paper constructed an evaluation model for regional ecological security assessment, and quantitatively evaluated the dynamic changes of ecological foot and ecological security in Henan province during the year from 1995 to 2008. The results show that the pet capita ecological footprint in Henan province has been increased from 1.2588 hm2 in 1995 to 2.6132 hm2 in 2008. The main reason is that the fossil-energy footprint increased 3-fold during the same time. The ecological deficit of per person has been increasing rapidly from 2000 with the growth from 1. 1616 hm2 to 2.1137 hm2, which results in the quick decrease of ecological security index from -1.6750 to -2.3735. This results show that the social-economic development in Henan province is unsustainable, and the ecological environment is in the state of insecurity, and even worse tendency. Finally, this paper gived suggestions to reduce ecological footprint and energy consumption, and maintain ecological security.关键词
