摘　　要：生态状况内在判断指标是反映生态状况自身变化情况的指标.生态状况处于何种阶段的判断指标,需要从层次性、系统性、现实性、重要性4个方面来考虑.综合考虑包括森林生态状况、土地荒漠化和沙化状况、水土流失状况、生物多样性状况、湿地生态状况、草原生态状况、农田生态状况、城市生态状况等8项指标,8项指标又可以细化为各自的分项指标.通过应用生态综合指数法对生态状况进行分析和综合评估,得出我国生态状况处于治理与破坏相持阶段这一重要结论.The inner assessment indicator on ecological status is one that reflects the change of ecological status itself. The assessment indicator on the phase of ecological status needs to be considered from 4 aspects： hierarchy, system, reality and importance. In general, the system of assessment indicators includes 8 indicators： forest ecological status, the status of land desertification and sandification, the status of land erosion, the status of biology diversity, wetland ecological status, prairie ecological status, the status of croplands and city ecological status, which can be further divided. Through an analysis and comprehensive evaluation using ecological comprehensive index （ECI）, an important conclusion is drawn that Chinese ecological status is in the balanceable phase between harness and destruction.
