基于生态足迹模型的山区生态经济协调发展定量评估--以贵州镇远县为例

采用国际上逐渐引起重视的衡量可持续发展的生物物理方法——生态足迹(Ecological Footprint),在简要介绍该理论方法的基础上,针对当前我国西部山地型生态经济类型区发展现状和面临的生态问题,以我国西南山区镇远县为例,采用该地区生态经济发展的截面资料,对其生态经济协调发展的状态进行了定量评估,并对其发展趋势做了保守估计。结果表明:目前地区的生态足迹需求小于生态供给能力,生态盈余为0.0677hm~2;生态空间供需结构存在明显的不对称性;自然资源利用率低于整个西部和东部沿海省份。以目前的趋势来看,生态盈余状态最多能维持5～15a。

Value of the Coordination to Eco-economy in Mountain District Based on Ecological Footprint Model

Ecological footprint which be put forward in recent years by ecological-economist is a useful indicator for measuring the pressure imposed by human on natural capital and also a powerful indicator for regional sus-tainability. On the base of analysis about EF theory' s background, the concept, theory and method is concisely introduced in this paper. By taking the mountain district of Zhen-yuan county as example, this paper applies the ecological footprint indicator to value the coordination state of the regional ecological economy, furthermore, we made a forecast to its development trend. After research, we can draw the conclusion as follows: now, the need of EF is less than the supply of EF in Zhen-yuan. surplus is 0.0677 hm2; the structure between supply and need is anisomerous; the ratio of use is much lower; according to current trend, ecological surplus could only maintain 5~15 years.
