摘  要:
诸多指标与河道生态系统相关而且彼此相关,找出其中对生态系统发展具有限制性意义的因子显得尤为重要。因子分析是在表达大部分信息的前提下,利用几个归纳性的综合指标取代原有多个变量的统计方法。运用该方法对新孟河水生态系统中发挥限制性作用的影响因子进行分析,通过数据处理和检验后的结果表明:悬浮物和水动力条件2项指标可以对生态系统中最重要的关注点水生生物产生直接的影响,且与生物多样性间存在显著的相关关系。

摘  要:
Many indexes are related to riverway ecosystem and correlated with each other,so it is significant to figure out limiting factors for the development of ecosystem. Factor analysis is a counting method substituting original variables with several conclusive comprehensive indexes under the premise of expressing most information. This method was applied to analyze influence factors that limit ecosystem of Xinmeng River. Through data processing and test,it was found that both suspensions and water power could directly affect aquatic organisms,which were most important concerns in ecosystem,and it showed significant correlation between these factors and biodiversity.
