Wild Resources of Ormosia purpureiflora and Its Spatial Distribution Pattern
摘要
Abstract
The geographical distribution and habitat of the key protected wild plant Ormosia purpureiflora were systematically studied by means of field germplasm resource investigation,and its population distribution pattern in Luofu Mountain was analyzed by using variance ratio.The results showed that O.purpureiflora was currently sporadically distributed in Luofu Mountain Provincial Nature Reserve in Guangdong and Nankunshan Provincial Nature Reserve in Longmen,Guangdong,with a very narrow range.A total of 2 144 individuals were surveyed in the two protected areas.More than 90%of the plants were shrubs with small crown width;and the rest were small arborescent.Ormosia purpureiflora grows in the middle of granite slopes and prefer warmth and humidity.The individuals in the population showed obvious aggregation distribution.This study has basically grasped the wild resource status and population spatial distribution pattern characteristics of O.purpureiflora,providing scientific basis for the protection and utilization of their germplasm resources.关键词
