Abstract: Sprouting is a common phenomenon for Karst plants,and this may closely relate to the site condition.Three 100m parallel transects were established along a top-down Karst hill slope in semi-humid evergreen broad-leaved forest in Shilin County in Yunnan Province.The sprouting characteristics of the plants(diameter at breast height or basal diameter ≥3cm)were surveyed on a 10m ×10m quadrat base.Regression analysis was used to analyze the relationship between the sprouting characteristic of plant and the distance of the plots to the hilltop on the slope(DTH).Results showed the number of all the sprouts,the average sprouts number of the sprouters and the average sprouts number of the stools decreased with increasing DTH.In contrast,the average of plant height increased with increasing distance from the hilltop.There were no significant relationships between the sprouting rate of stools,the average DBH of the stools and distance from the hilltop.So,we can conclude that taller plants and less sprouting will be found with increasing DTH,and shorter plants and more sprouting with decreasing DTH on the Karst hill slope.
