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,Zanthoxylum planispinum,Rhamnus heterophylla,Rubus biflorus,and Pyracantha fortuneana;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.[Ch,4 tab. 15 ref.]
