Among them there are 1 541 species of seed plant,which belong to 492 genera and 90 families and only accounts for about 6.26% of whole country flora. In Shiyanghe basin, there are 1 361 species of forage plants, 547 species of drug-using plants, 148 species of ornamental plants, 138 species of vegetable plants, 62 species of fibre plants, 60 species of honey plants, 42 species of aromatic plants, 40 species of starch plants, 37 species of oilseed plants and 26 species of pesticide plants. There are abundant genetic resources in Shiyanghe basin. Among them there are 115 species of sand plants, 172 species of salt plants, 269 species of xerophyte and the extreme xerophyte plants and 340 species of hardy plants. The result is objectively reflected status of seed plant diversity in Shiyanghe basin. Furthermore, strategies for conserving biodiversity in Shiyanghe basin were suggested.
