Research of Wetland Characteristic in Wanfoshan Danxia Geomorphic Zone

In order to investigate the natural heritage value of biological diversity in Wanfoshan Danxia geomorphic zone,the wetland vegetation characteristic was researched.The results showed that there were 87 species 59 genera 33 families wetland plants in Wanfoshan,there were 4 species 4 genera 4 families fern and 83 species 55 genera 29 families angiosperm in these plants.There were 40 species marsh plants,40 species aquatic plants and 7 species wetland plants in the angiosperm plants.The distribution of the plants in the faculty and category was dispersed.There were 2 vegetation type and 18 groups that was marsh and aquatic.The wetland extensive characteristic was prominent and the terrain characteristic was strong.World blazon component accounted for 34.55%.There were 9 kinds of wetland in 15 distributing areas in china.There were 2 kinds of first and second protection plant of country in this area.The distributing area of relic plant isoetes sinensis was 1.8km×11.2km,actual community area was 8 700m2,78 309 cluster and the largest density was 32 cluster/m2.
