摘要
以沈水湾公园内的20个样地为对象进行植物群落结构的调查与研究。分析了样地内植物的组成、群落的层次结构特征和季相特征。结果表明,沈水湾公园植物群落的物种组成过于集中,相同物种规格相近;水平结构为片状组合,混交性较差;垂直结构为乔灌草3个层次,其中乔木层的优势最明显,灌木层和草本层的优势较差;季相上虽在栽植时考虑到了四季有景,但常绿树种的数量仍十分有限。通过沈阳地区最常见的自然植物群落—油松栎林的结构特征对沈水湾公园植物群落提出了优化对策。
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.
