摘要
根据太湖水华爆发特点及文献资料检索,从气象、水动力、化学和生物等4个方面筛选出太湖水华爆发的17个要素,利用解释结构模型(ISM)分析了各要素之间的直接(因果)关系和间接关系,推导出太湖水华爆发要素整体关联层次结构图,从6个层次上直观反映了水华爆发过程,从系统角度分析了水华爆发原因,为水华预防及治理提供了若干参考依据。
According to the characteristic of algae bloom in the Taihu Lake and a lot of research literatures review, 17 essential factors associated with the algae bloom were selected from different environmental aspects of meteorology, lake-current, chemistry and biology. Direct (causal) and indirect relations among these factors were analysed using the interpretative structural modeling (ISM) method. The resulting integral relation structure diagram of those algae bloom essential factors showed clearly the entire course of algae bloom in six levels. It gave reason of algae bloom from the point of system and offers reference basis for guarding against algae bloom.
