Niche characteristics for dominant species of a wild Pueraria lobata community in the Guizhou Karst Region
摘要
Abstract
Based on plots of the Pueraria lobata community in the karst area of Guizhou, the niche width, niche proportional similarity, and population overlap of 16 dominant species were analyzed. Results demonstrated that; 1) the top six niche breadths from first to sixth were Pueraria lobata, Lindera communis , Zan-thoxylum planispinum, Rhamnus heterophylla, Rubus biflorus, and Pyracantha fortune ana; 2) Pueraria lobata adapted well to the rocky, desertified environment of the karst; 3) the proportion of niche similarity for all species pairs was between 0 and 1 with the degree of similarity for resource use being different; 4) these 16 populations did not show a strong niche overlap as different resource use was noted; and 5) primary species in this study with a higher niche width did not have a higher niche overlap. Although for sustainable development some prospects of using Pueraria lobata for feed have been mentioned in the literature, increases in mowing and other human interference measures would be a drawback; also the lack of resource sharing for the Pueraria lobata community meant it was unstable.
