摘要
简述生态环境因子划分标准，尝试确立一种新的划分方案，论述扰动因子研究内容，讨论最佳生态原则。根据环境因子的相互关系和存在特点及对生物的作用，环境因子首先可划分为时刻存在作用因子和间断发生作用因子。前者研究的核心是其固有的规律性和限制性及其时对生物的作用，后者研究的核心是其发生的时间强度和频次及其对生物的作用。三条最佳生态原则分别是间断发生作用因子发生时间、强度和频次的限制原则，它可为经营管理生态系统提供具体的理论指导。
According to thecharacterkdcs of environmental factors and their inter relations andresponses of organisms to enviromental factors.The cnviromental factors might be dividedinto followings;1.Continuous factors.(1).Prifnary periodic factors. (2).derivcd periodic factors.(3).stable factors. 2.Discontinuous factors (disturbance factors). (4). Periodic factors(natural)(5).irregular factors(natural)(6). man-made factors(maybe continuous). Any factor occurres intervally has optimum occurence time ,optimum intensity and op-timum frequency, They are optimum principlcs and limited principles.
