- 摘要:
- 以长春市净月潭森林公园为研究对象，采用线路调查、定点辐射状调查和特殊地区重点调查相结合的方法，研究了该地区种子植物种类组成及属的区系地理成分，以期为野生植物多样性保护和科学管理提供科学依据。结果表明：该地区种子植物种类组成丰富，共87科 314属503种，其中裸子植物2科6属9种，被子植物85科308属494种（双子叶植物68科256属415种，单子叶植物17科52属79种）。优势科现象明显，寡属科、单属科比率较高。该地区植物区系组成复杂，共有15个分布区类型和9个变型；温带成分占主体（212属，占总属数的81.54%），表明了该区温带植物区系历史起源；但特有现象不明显。与相邻7个地区的区系多样性比较和聚类分析表明，香农-维纳指数差异明显（2.557~2.960），其中老秃顶子和努鲁儿虎山较高，五大连池和长白山较低；而辛普森多样性指数差异并不显著（0.743~0.811）。聚类分析表明，净月潭植物区系与长白山、张广才岭地区关系较近。
- Abstract:
- The research selected Jingyuetan Forest Park in Changchun as research object,floristic composition and floristic elements of spermatophyte in this area were studied by using method of combination of line survey,spot radiation survey and special area investigation,in order to provide scientific basis for the protection and scientific management of wild plant diversity.The results showed that the floristic composition was abundant in this area,there were 503 species,314 genera and 87 families,which contained 9 species,6 genera and 2 families of gymnosperms and 494 species,308 genera and 85 families of angiosperm.It was notable in dominant family,the single-genera and few-genera of angiosperm are rich.The composition of floristic was complex,it contained 15 distribution types and 9 variants types.The temperate elements of genera dominate obviously amounting to 212 genera and making up 81.54% of the genus total in the park.China unique genera was not obvious.Compared with adjacent area,floristic Shannon-Wiener index were obviously different form other 7 area (2.557-2.960),while Simpson′s diversity index were not (0.743-0.811).Shannon-Wiener index of Laotudingzi and Nuluer Hu Mountain were quite high,while Wudalianchi and Changbai Mountain were low.Greater similarity was found among Jingyuetan Forest Park,Changbai Mountain and Zhangguangcai Mountains by cluster analysis.
