Results show that phanerophytes is the dominant life form in the three forests, in which micro-phanerophytes is in the largest proportion, and then followed by hemicryptophytes. In the three communities, the principal leaf size is mesophyl1, the main light eco-form is heliophyle, and the dominating water eco-form is mesophyte.

结果发现，3个群落都以高位芽植物为主，其次为地面芽植物；在高位芽植物中又都以小高位芽植物比例较高；3个群落的叶型谱以小型叶为主，光照生态类型谱以阳生种类为主，水分生态类型谱以中生种类占优势。
