Research on vegetation species and coverage situation of golf course cluster at Yongding River

Yongding River is considered as one of sandstorm resources to Beijing under long term drought in spring or fall. Plant species and vegetation coverage were investigated at 48 plots in 12 sampling sites inside or outside of golf courses from Luzhou Bridge to the beginning line of Raoshang along the Golf Course Cluster. The results showed that plant species varied greatly among the sites, and vegetation coverage inside was higher than that outside of golf (P0.01), in descendent order was greens (95%), fairways (more than 60%), roughs (more than 60%) and the side area (less than 40% in 60% area). The outside of golf area was erosible by wind.
