Detailed Ecological Footprint Accounting of Liaoning in 2006

Chinese Journal of Population,Resources and Environment 2008年第4期6卷 78-87页

Ecological footprint (EF) has received considerable attention as a useful indicator in the context of sustainable development. So far, EF has been used in numerous studies by academies, organizations and government authorities. However, the results of these studies failed to be comparable directly with each other due to imprecise data sets, unmodified accounting methods of pasture and fossil energy, ignored secondary products, undefined process of calculating yield factors and improper biocapacity for biodiversity. In this paper, we elaborated on EF estimating methods from six categories of consumption in order to overcome the limitations above. We adopted precise data and revised methods, calculated EF of some secondary products, introduced weighted factor to calculate yield factors and adjusted biocapacity by an appropriate amount. Meanwhile, we investigated the resource consumption of Liaoning Province in 2006 to assess EF. Its results showed that Liaoning Province overused its natural capital and was in an unsustainable state. We concluded that two specific problems that had arisen in EF assessment and gave some suggestions for Liaoning Province to improve its unsustainable state.

Quantitative evaluation of sustainable development based on ecological footprint method: a case study of Tianjin

Ecological Economy 2008年第2期4卷 172-179页

Since the coneept of sustainable devetopment emerged in the late 1980s, more and more countries and regions have been utilizing sustainable development as their developing stratety. But decades have passed without any effective methods available to quantitatively assess sustainable development. Since the ecological footprint evaluation method initiated in 1992, it has become popular in quantitative assessment of sustainable development because of its convenience, easy-understanding, and rehability. As one of the biggest coastal cities in north China and the economic center of the Bohai Coastal Region, Tianjin＇s gross domestic product （GDP） was 369. 762 billion yuan in 2005, accounting for 2.0°of the whole nation＇s GDP. The paper analyzes Tianjin＇s development with the ecological footprint method, and the results show that Tianjin＇s ecoiogical footprint and biocapacity in 2005 were 2.507gha/cap and 0.2 76gha/cap respectively. The ecological deficit was 2.230gha/*** from 1980 to 2005,Tianjin＇s ecological deficit per 10^4 yuan GDP decreased;while per capita ecological deficit has been tending to increase rapidly in recent *** these result demonstrate that Tianjin is in a state of unsustainable development.
