Abstract:

This thesis made investigations and studies of plant community structure according to the Shenshuiwan park’s 20 samples. It analyzed plant compositions, layer structure characteristics and seasonal characteristics. The results showed that the species composition is over concentrated and the same species is near specifications. Horizontal structure is flaky combination and poor promiscuity. The vertical structure includes trees、shrubs and grass. The most obvious advantage layer is trees. The advantage of shrubs and grass is poor. Although the park considered seasons in planting trees, the number of evergreen is still limited. This thesis will put forward optimized countermeasures to the existing plant communities of Shenshuiwan park through the structural characteristics of Shenyang common natural plant communities.
