榆次玉湖公园种子植物多样性的研究

Studies on the Diversity of Seed Plants in Yuhu Park,Shanxi Province

山西省晋中市榆次区玉湖公园的种子植物呈现多样性的特点:公园内共有种子植物75种,隶属于33科、58属;公园内种子植物的生活型有草本、灌木和乔木3种,其中乔木种类最多;公园种子植物果实类型有12类,果实为蒴果的种类最多;公园内种子植物除有绿化的作用外,还有药用、观赏、作为工业原料等多种重要的经济用途.加强对公园内种子植物的保护和开发工作,需要大力开展科学研究工作,制定发展计划,根据地方资源建立特色产品,合理引进外来种.

The diversity of seed plant in Yuhu Park was analyzed and the results are as follows： （1）There are 75 species ofseed plants,belonging to 58 genera and 33 families,including 10 species of Gymnosperm （7 genera and 10 families） and 65species of Angiosperm （51 genera and 28 families）. （2）The living styles fall into 3 types： herbs,bushes and trees. The type oftrees has the most species,being 39 species. （3）There are many types of fruit,amounting 12 types. And the type of capsule seedplant is 22 species,which is the most. （4）Most of the seed plants in the park can afforest environment,meanwhile,they havemany economical use,such as for medical purpose,industrial materials and watching. At the same time,some suggestions aboutprotection and development of the seed plant in Yuhu Park have been stated,as following： undertaking more scientific researches,setting up development routine,establishing special products and introducing some extra-species reasonably.
