Based on formal ImPACT identity which describes environmental impacts (Im) as a function of population(P), affluence(A), intensity use(C) and efficiency(T), a new "ImPACTS" identity as a framework for sustainability science was produced, where S denote the level of social resources, m is assigned to management and I is changed from formal environmental impacts to the trade-off between environmental impacts and development.

Based on formal ImPACT identity which describes environmental impacts (Im) as a function of population(P), affluence(A), intensity use(C) and efficiency(T), a new "ImPACTS" identity as a framework for sustainability science was produced, where S denote the level of social resources, m is assigned to management and I is changed from formal environmental impacts to the trade-off between environmental impacts and development. Finally, we demonstrate the utility of ImPACTS by performing an empirical analysis of our integrated impacts assessment on the Earth by using existing data of Ecological footprint and Human development index. In an attempt to analyse the relationship between ecological footprint and social development using existing data, developed countries showed a great advantage over developing countries in terms of energy resource use efficiency due to their social and technological development. Global warming shows that humanity has gone beyond the sustainable scale of the Earth. We thus suggest that every country should increase its global share of ecological footprints within the sustainable scale of the Earth, rather than simply decrease its ecological footprints. The reason why current analysis contradicts the conventional ecological footprint analysis is that ecological footprint's concept simply considers the land embodied in goods and attributes a high ecological footprint value to high-income countries, and effects of trade on social development and in turn on the environment have not been considered. The ecological footprint analysis ignores the effects of development mainly in the stock of social resources on environment. The critical point in sustainable development is to harmonize environment and development. Examples from water shortage in northern China and China's food security and world energy consumption show that managing and mobilizing social resources should be considered as an alternative to mitigating human impacts on the environment and adapting to these impacts.

可持续发展要求必须在一个地球的约束下,最大限度地满足人类的发展需求。通过分析生态足迹与人类社会发展的关系,从可更新和不可更新资源利用效益角度来看,在发展的可持续性上发达国家比发展中国家在利用地球容纳环境和社会期望方面具有明显的优势。同时,气候变暖的事实说明,人类对不可更新化石燃料的开采和利用速率已经超过地球上生态系统吸收CO的能力。各国要取得社会发展并使之具有可持续性,应该在地球的可持续性尺2度范围内增加自己的全球足迹份额,而不是简单的减少足迹。以中国的南水北调、北粮南运,粮食安全及世界石油消费利用为例说明了社会资源在缓解和减轻环境影响方面的作用。在剖析经典的IPAT等式及其变种等式ImPACT分析框架的基础上,提出了一个新的可持续性评价研究框架—ImPACTS等式,并讨论了新等式的政策含义。在ImPACTS等式中,新增项S——代表社会资源的状态(社会发展状态),m代表管理,用来强调人类采用协调的方式来解决超过可持续性尺度这一问题的重要性,I因此变成了集成的影响评价—对环境的影响和社会发——展的损益评价。

Growing evidence demonstrated that human has dramatically altered the global environment.Identifying the specific forces driving environmental impacts is a hot topic in the field of sustainable development.One key limitation to a precise understanding of anthropogenic impacts is the absence of a set of refined analytic tools.Firstly,the analytic utility of the well-known IPAT identity and its newly advance,including the developed ImPACT identity and STIRPAT model,is assessed.Then the stochastic model in details and illustrated its application are introduced.With STIRPAT,it is easy to determine the population and affluence elasticity of impact,using cross-sectional,time-series data,and the antilog of the residuals in STIRPAT can be interpreted as a specific multiplier of technology on environmental impacts or the eco-efficiency of technology.Secondly,taking China as a case,the anthropogenic driving forces of environmental impacts using the STIRPAT model and cross-sectional data in 1999 is unpacked.The ecological footprint was taken as the index of environmental impacts due to its strength in accounting for impacts wherever they occur geographically and providing a common unit of measurement for comparing diverse types of impacts.A series of index like urbanization rate,economic structure,economic system position and natural location are considered in the empirical model.Among these variables,the social and political variables like economic system position and natural location are coded as dummy variables.The quadratic terms of affluence and urbanization rate are included to examine the environmental Kuznets curve hypothesis.Thirdly,the analysis results show that population has a proportional effect(approximately unit elasticity) on ecological footprint,and affluence monotonically increases the ecological footprint with a relative low degree than population. Natural location appears to affect the ecological footprint,with southern China having considerably lower impact than northern China.At he same time,the technological eco-efficiency of sample provinces was discussed in details.The most important finding in the empirical study was that overall finding don't support the environmental Kuznets curve hypothesis.Finally we discussed the advantage of using the STIRPAT and analyses the reason why not support the environmental Kuznets curve hypothesis in empirical analysis.Based on the analysis of future environmental impacts using estimation model,we put forward that the social adaptation should be taken as the direction of succeeding research.

辨明人类活动各因素对环境影响作用的大小,并依此找寻发展的对策是当前可持续发展研究的核心问题之一.分析了IPAT等式在分解环境影响中人文因素的作用;采用生态足迹作为环境影响的测量指标,利用STIRPAT模型,以1999年中国各省市的截面数据为例,分析了人口数量、富裕程度、现代化及经济区位和自然区位对环境影响的具体作用,并在此基础上探讨了中国各省(市)的技术生态效益.结果表明:人口数量是当前环境影响的一个主要驱动因子,环境影响与人口数量近同比例变化,富裕程度或现代化程度增加也将加剧人类对环境的影响.在观测数据范围内,分析结果不支持存在环境Kuznets曲线的观点.最后分析讨论了不支持存在环境Kuznets曲线的原因及STIRPAT模型的优缺点,并指出社会适应性能力可作为下一步深入研究的方向.

Analysis of environment impact of human activities has become a hot topic in the current time.On the basis of introducing the ImPACT identity,combined with a case study of virtual water consumption in Gansu province during 1990-2003,the utility of the ImPACT identity in environment impact assessment is explored.It is found that,compared with the period of 1990-1995,in 1996-2000 and 2001-2003 income of Gansu province increases dramatically,and use intensity and efficiency improve greatly,which...

Analysis of environment impact of human activities has become a hot topic in the current time.On the basis of introducing the ImPACT identity,combined with a case study of virtual water consumption in Gansu province during 1990-2003,the utility of the ImPACT identity in environment impact assessment is explored.It is found that,compared with the period of 1990-1995,in 1996-2000 and 2001-2003 income of Gansu province increases dramatically,and use intensity and efficiency improve greatly,which adjust the virtual water consumption.Income elasticity analysis shows that when income increases 1%,the amount of agricultural production consumption per capital will increase 0.13%,while use intensity will decrease 0.87% and environment impact will increase 0.14%.Comparison analysis shows that,in 2000,the virtual water intensity of rural area(0.706 m~(3)5Yuan~-1) is dramatically higher than that of urban(0.051 m~(3)5Yuan~-1).Adjusting the consumption structure in a proper way will do good to reduce environment impact.Setting up an environment objective and examining the responsibility of driving forces shows that higher objective requires higher improvement for both producer and consumer.As the environment objective of achieving 50% of the amount of virtual water consumption in 2003,with the use intensity decrease by 1.5 times and efficiency improve one time based on the "actual situation" of the period 1990-2003,it is possible to achieve the objective in a reasonable period(28 years) meanwhile with a more rapid economic development.In conclusion,ImPACT identity can be used to analyze the effect of driving forces on environment impact quantificationally and it is significant for seeking sustainable policies.

应用ImPACT等式,分析了甘肃省1990—2003年虚拟水消费中人类活动对环境的影响.结果表明:相比1990—1995年,1996—2000年和2001—2003年甘肃省收入显著提高,而使用强度(单位GDP的农产品消费量)和效率(单位农产品消耗的虚拟水量)大幅度改善,对环境影响(虚拟水消费量)起到了调节作用.收入弹性分析表明,收入增加1%将引起人均农产品消费量增加0.13%,使用强度下降0.87%,而环境影响增加0.14%.2000年甘肃省城镇和农村虚拟水消费对比分析表明,农村的虚拟水强度(0.706 m3.元-1)显著高于城镇(0.051 m3.元-1),合理改善消费结构能降低虚拟水强度从而减轻对环境的影响.应用ImPACT等式设置环境目标并检验其可行性,结果表明:在1990—2003年的基础上,使用强度降低1.5倍,效率提高1倍,能够保障经济的增长,并在合理的时间范围内(28 a)实现虚拟水消费量减少到2003年的50%,是一种可行的选择方案.
