Abstract

In this study,through the investigation of the population and resource situation of Parrotia subaequalis at the habitat in Jinzhai,Anhui Province,the characteristics of the population were analyzed from the spatial distribution,the population structure,age and the spatial structure and so on.First,the results show that the Parrotia subaequalis is clustered distributed on the low mountains with the elevation of 400~700m.Second,most of the population are auxiliary species,and only some individual population can be the dominant species in local areas.Third,most are young trees in Ⅱ and Ⅲ age-classes,and they are mainly seed propagation,but the tiller initiation is also the important breeding way of Parrotia subaequalis.Forth,there is a negative phenomenon in the mortality of the population of Parrotia subaequalis,and that means there are rapid development or decline in the population due to high volatility.Therefore,it is urgent to take protection measures for Parrotia subaequalis in Jinzhai,and the artificial breeding and endangered mechanism research of Parrotia subaequalis should be propsed.

Key words： Parrotia subaequalis; population distribution; population structure; rare and endangered species; Jinzhai County
