| 摘 要： | 本研究以＂空间序列＂代替＂时间序列＂的研究方法,探讨了云南大理苍山地区火烧迹地群落演替进程对植物多样性的影响。结果表明,在不同火烧时期的样方中,共记录种子植物70种,其中草本植物44种,占总物种数的63%左右,同时记录木本植物共26种,占总物种数的37%左右。植物生活型组成以草本植物为主;温带区系成分所占比重略高于热带成分,这可能与样方所处的生物地理位置和相对较高海拔有关;随着演替进程的推移,植物群落的物种多样性呈显著单调递减趋势,这可能与群落内部透光性的改善和营养物质的回归有关。

| Abstract: | The effects of successions of communities on plant species diversity were investigated based on the methods of transformation of spaces series into time series.The results showed that 70 plant species were recorded,including 44 herb species and 26 woody species.The life forms were mainly composed by herbs.The proportions of temperate elements were slightly much greater than that of tropical elements,which may be due to the location of biogeography and altitude.With the progress of succession,a decreasing tr... |
