  • Medicinal Plant Diversity at Cham Chu Nature Reserve Area, Tuyen Quang Province

    • Authors: Pham, Thi Oanh; Ngo, Duc Phuong; Do, Thi Xuyen; Nguyen, Trung Thanh (2018)

  • A total of 443 medicinal plant species were recorded in Cham Chu Nature Reserve Area belonging to 325 genera and 120 families. Most of the medicinal plant species in Cham Chu Nature Reserve Area are Angiosperms with 425 species (95.94%) (360 Dicotyledonae, 65 Monocotyledonae), 6 species belong to the Gymnosperms (1.35%), 10 species are Polypodiophyta (2.26%), Psilotophyta and Lycopodiophyta are only one species (0.23%). The richest 3 families are Euphorbiaceae with 22 (4.97%) species, Rubiaceae with 17 (3.83%) species and Asteraceae ranks third, with 16 (3.61%) species, respectively. When the medicinal plant of the area are analysed by Raunkiaer’s life form system, the results are fol...

  • The Relationships Between Environmental Factors and Phytoplankton Diversity Indices in some Estuarine Ecosystems of Vietnam

    • Authors: Nguyen, Thu Hien; Do, Thi Xuyen; Nguyen, Trung Thanh (2016)

  • This study was carried out from 2011, 2012 and 2015 with 4 times at 10 stations of each estuary from 7 estuarine ecosystems. They are Van Uc (Thai Binh river), Ba Lat (Red river), Thuan An (Huong river), Cua Dai (Thu Bon - Vu Gia river), Soai Rap (Dong Nai river), Co Chien (Tien river) and Dinh An (Hau river). The results showed that the physico-chemical parameters are mostly met the standard limit for aquatic lives, except for COD. The salinity level of the estuaries in Center and South are higher than the estuaries in North. Five algal divisions have been found in these estuaries are Bacillariophyta, Chlorophyta, Cyanobacteriophyta, Pyrrophyta and Dinophyta. Among of them, Diatom (B...
