Based on 18 climatic factors of 34 climatological stations relative to ecology, the classification of ecological climatic distict of Fenhe River basin is studied by Q-cluster analysis method.

This paper chooses the representative Fen River in TaiYuan city zone as the research background, and applies systems method to research the black and stink of river.

In addition, the results of numerical simulation were in agreement with the results of actual water quality monitoring, showing that the method was reasonable and practical.

The trunk and main branches, such as Weihe River and Fenhe River, were the axletree of economic development in the Yellow River basin.

In addition to a large number of ice detection mechanism experiments in the laboratory, but also the use of old-fashioned ice thickness sensor to do on-site engineering application test in Fen river.
