摘　　要：在生命周期评价(LCA)中土地利用的生态影响受到了越来越多的关注,但土地利用生态影响特征化模型和特征化因子尚未很好确定,问题的关键在于如何科学选择评价指标.根据LCA的需要,基于土地的四个主要功能,从指标相关性、稳定性、数据可得性等方面开展深入分析,最终确定土地利用面积、占用时间、地形、NPP和有机质含量等5个指标作为LCA中土地利用生态影响评价指标,可据此建立特征化模型并得到相应的特征化因子.Ecological impacts of land use have been received more and more attentions in LCA,but the characterization model and factors have not been confirmed yet.The key question is how to choose the scientific ecological impact indicators.Based on the main functions of land,an indicator dataset for land use impact assessment in LCA was proposed from the viewpoint of correlation,stability,availabilities and so on.The indicator dataset is consist of five indicators,namely land use area,duration,terrain,NPP and soil organic matter.It is possible to create feasible characterization model and derive characterization factors.
