Investigation on alt wetland vegetation of Miaodao mountains in Yuexi county

The alt wetland vegetation grown under the valley forest with 1.4 hm^2 total area in Miaodao mountains of Yuexi county was investigated. The result indicates there are vascular plants of 90 families, 180 genera,258 species with the predominance of Polygonaceae, Fabeaceae, Rosaceae, Cyperaceae, Compositae and Gramineae.

The living form of community with middling leaf grade is composed of supraterraneous bud, ground bud and hydrophyte. There are four layers of arbor, shrub, herbage and plant between layers in the community structure. The species diversity in herbage layer is more than that in shrub one.
