Research On Plant Community Structure And Ecological Benefits Of Gulf Forest Park In Shanghai City

The plant community structure and the ecological benefits of the Gulf Forest Park were studied in the paper. According to the results,some proposals were put forward for the further construction of the Gulf Forest Park. The primary conclusion as following:1.The plant diameters of arbors in the Park ranked from 4 cm to 10 cm, which indicates that the forest grew equably.2.There is a difference in some extent in the diversity among plant communities. And the diversity of the community of Zilkova schneideriana+Celtis sinensis-Pittosporum tobiia-Veronica didyma Tenore is the highest in all the communities.3. As to all the plant in the Gulf Forest Park, the sequence is herbage layer>arbor layer>shrub layer on such ingredients as the abundance percent of species S, Simpson index, Shannon-Wienner index and Pielou index.4.There also have some problems as simple structure and poor heterogeneity in space of the Gulf Forest Park; less species in per plant community, the higher value of importance of superior species etc.5. The Gulf Forest Park environmental cleanliness is high.The aero-anion percent and pureness degree of atmosphere in the Gulf Forest Park is higher than city zone all the day. The study shows the aero-anion level is higher in arbor+shrub+grass typical forest collocation model or submarginal water area.6.The content of heavy metal of leaves in 10 kinds of primary trees in the Gulf Forest Park is lower than that in 8 kinds of primary trees in city zone significantly.7.The average temperature of day in the Gulf Forest Park is 10C lower than that in the park at city zone, and that number of the highest temperature of day is about 20C. The average relative humidity of day of different parts in the Gulf Forest Park is 62.94%, the number is 9% higher than the one in the others at the city zone.
