摘要
环境承载力评价是判断区域能否可持续发展的重要技术手段之一.现有综合评价多混淆压力指标和状态指标、压力指标和承载力指标,采用的线性相加难以真实反映承载状态,且未能准确、定量地判断超载或富载的程度.为克服上述问题,基于对环境承载力组成的量化计算,尝试构建向量-承载剩余率模型评价区域环境承载状态.同时,给出环境承载状态的指示指标以及环境压力的控制指标.
Integrated Assessment of Environmental Carrying Capacity(ECC) is one of important tool to detect status of sustainable development for a region.Most of traditional assessments of ECC couldn't discriminate pressure index and state index,and misused pressure index with carrying capacity index.They might not present a real carrying status using linear plus model.Most important is that they couldn't bring out accurate and quantitative assessment results,and couldn't tell the specific degree of over-carrying or carrying.A new model,vector-capacity surplus model,based on computing all parts of ECC,is proposed.Except the carrying capacity index system,a state index system rapidly indicating carrying status and a pressure-mitigated index system showing the level of reducing environmental pressures are suggested.
