摘要
大型工程建设对区域社会、环境、经济造成长期影响,关系到区域的可持续发展。从项目评价研究来看,环境评价实际上已经独立成为一个体系,而社会评价仅停留在定性层面,因此需要研究以全寿命期成本为核心的项目评价。项目生态成本包括社会成本、环境成本和工程成本,需要厘清三者的边界。现行的工程成本来自货币化的相对体系,不能解决资源的绝对价值的度量问题,因此资源绝对价值度量的量化模型亟待研究。基于系统生态学的能值分析能够计算生态系统的物质流动和能量传递,并直接把资源价值转化为太阳能值质量(Emergy)。
Large-scale project construction impacts on regional society, economy and environment for a long period.It also relates to the sustainable development. That appears the project evaluation has the essential obstinate disease. In view of project evaluation, environmental evaluation has already become a independent system in practice, as well as the social evaluation stopped on the qualitative level. Thus the project evaluation is needed taking life-cycle cost as the core. In fact, the economic evaluation of project includes social cost, environmental cost, and social cost. The research scope of large-scale project cost should be expurgated on the boundaries, especially between the environment and society cost. The existing engineering cost come from the financial system, it can not control the measurement of resource absolute value. Moreover, the absolute value measurement of resource needs to study quantitative model right now. The Energy analysis based on systematic ecology could calculate the material flowing and energy transferring of ecological system. The method can apply to any kind and level ecological energy system including economic-social system. It is very significant on theory and practice that it extends the applied fields of ecology, enriches construction project management theory and assists to the project evaluation and investment decision.
