Finally, this paper analyzed the status and problems about the landscape of waterfront of Haihe results of the study are as follows:(1)The form of revetment is four. Eight plots are the rectangular cross-section, are most, secondly, six plots are the double rectangular cross-section, again, four plots bination of double-cross-section, finally only one plot is natural cross-section. The proportion is 8:6:4:1.(2)There are 82 kinds of ornamental plants, belonging to 34 families and 60 genera, the species ofArbor layer and Shrub layer and Herb layer respectivelyare 40 to 20 and 22, the proportion is 2:1:.
