生态环境预警的理论和方法探讨

An Approach on the Theory and Methodology of Ecological and Environmental Warning

生态环境预警是对人类活动引起的生态系统退化与环境质量恶化进行预测。并提出及时的警告。论文对环境影响强度、环境影响累积量、环境质量现状、环境标准、环境容量、环境影响响应、环境影响后果的概念作了较准确和规范的阐述，对不同生态环境预警类型进行分析，并给出定理评价的数学表达公式。

Ecological and environmental warning is defined that the forecast and warning must be given on time for ecologicaldegrading or environmental quality deteriorating caused by human activities. The paper explicates rigorously and normally someconcepts of the density of evironmental impact,accumulation of environmental impact,present environmental quality,environmentalquality standard,environmental capacity respondency of environmental impact,result of environmental impact. Maintime it analysesdifferent types of ecological and environmental warning,and gives out their mathemal formulas for quantitative valuation.
