Dynamic Analysis on the Emergy Value of Langfang Industrial Ecosystem
摘要
Abstract
Using emergy theory and method, the development of langfang industrial ecosystem during 1998 - 2009 was analyzed. An index system, which involved three aspects of emergy flow, emergy efficiency and system sustainability, was constructed to evaluate the Emergy of Langfang industrial ecosystem. The results showed that the emergy flow all increased to varying degrees, the emergy self-sufficiency was high, the environment load rate increased sharply and the potential population carrying capacity was far less than actual population quantity. All these indicated ttial the development of Langfang industrial ecosystem was largely dependent on local resources, especially those nonrenewable resources, at the cost of local resources and environment, the utilization degree of resources in other places was not high. The sustainable development index of the ecosystem showed significant increasing trend, while the eco-efficiency index firstly declined and then improved, the e-cosystem presented unsustainble development trend.关键词
