广西1990-2002年生态足迹动态分析

生态足迹是一种评估区域可持续发展程度和量度维持人类的自然资源消费量的帐户工具。本文以广西为例，结广西1990、1995、2002年三个时期的生态足迹及生态承载力进行计算和分析，结果表明，12年以来，广西人均生态足迹和生态赤字均呈快速增长态势，人均生态足迹从1990年的为0.9908hm^2增加至2002年的1.3369hm^2；人均生态足迹赤字从1990年的0.5821hm^2增加至0.9521hm^2。这表明人类对自然资源的利用已经超过了生态系统的承载能力，区域生态经济系统处于人类过度开发利用的重压之下，必须引起重视。

ECOLOGICAL FOOTPRINT DYNAMIC ANALYSIS OF GUANGXI CHUANG AUTONOMOUS REGION,FROM 1990 TO 2002

Ecological footprint is a significant accounting tool for overall assessment of the status of sustainable development, and a comprehensive indicator for human resources consumption. It was developed in the early 1990s by M. Wackernagel and W. Rees. In this paper, the three ecological footprints of Guangxi zhuang Autonomous Region in 1990,1995,2002 were calculated,and the status of sustainable development was analyzed based on the data of the statistical yearbooks.The result shows that ecological footprint per capita of Guangxi quickly increased from 0.9908hm2 in 1990 to 1.3369hm2 in 2002,and ecological deficit per capita of Guangxi had quickly increased from 0.5821hm2 in 1990 to 0.9521hm2 in 2002. The ecological footprint deficit shows that the human load has already stayed beyond the regional ecological capacity,and the regional natural ecosystem is under great pressure of human activities.
