Investigation and Evaluation on the Terrestrial Plants in Longhu Area of Shantou Special Economic Zone

Based on the field investigation and home analysis, the specific composition of terrestrial plants and vegetation types were described, the pollutant contents of do- minant species were discussed, and the ecological environmental quality of Longhu area was evaluated in this paper. The result shows that the plant specific compo- sition of the area is rich, there is no original vegetation, and over-standard rates of heavy metal in plant samples are relatively high. The situation of plant pollu- tion is similiar to that of water and soil.
