Abstract:

This paper investigated the waterside forests of 88 countries in Fujian by using stratified sampling method. The results showed the plant composition included 30 families, 42 genera and 48 species. The species were mainly composed of mountainous type, hill type and flat type, while coastal type was relatively scarce. The plant numbers of flat type was richest, followed by coastal type and mountainous type, while hill type was relatively rare. The coast type was dominated by ornamental and fruit species, and the main applied species included Dimocarpus longgana,Phyllostachys edulis,Dendrocalamopsis oldhami,Celtis sinensis,Liquidambar formosana,Pterocarya stenoptera,Cinnamomum camphora,Salix babylonica,Salix dunnii,and Phragmites australis. The waterside forests mainly distributed by rivers, followed by rills, and further less by the ponds. Most of the forests were distributed unilaterally and bilaterally along the waters, while the minority distributed around the waters. There were continuous and scatter distribution patterns, and the two had similar number proportion. Distribution length was usually within 50 meters, some distribution could be over 100 meters, and the length between 50 and 100 meters was scarcely found. The plants on waterside forests mainly were large and medium in dimension, with the average height of most plants around 10 meters. The forests were healthy, and the proportion of health plants, fair plants and poor plants were 15.82%,75.24%,8.94%, respectively.
