麻竹林地坡中、下部的凋落物现存量、持水性,以及土壤的持水能力都显著高于坡上部,同时,3个坡位的土壤持水能力总体显著高于农耕地。因此,麻竹作为主要造林竹种,生态效益显著,在水源涵养功能方面起着良好的作用,在营林时需考虑坡位的立地条件或加强管护力度,以发挥更大的生态效益,同时获取更大的经济和社会效益。
痳竹林地坡中、下部的凋落物現存量、持水性,以及土壤的持水能力都顯著高于坡上部,同時,3箇坡位的土壤持水能力總體顯著高于農耕地。因此,痳竹作為主要造林竹種,生態效益顯著,在水源涵養功能方麵起著良好的作用,在營林時需攷慮坡位的立地條件或加彊管護力度,以髮揮更大的生態效益,同時穫取更大的經濟和社會效益。

Litter mass and underground water-holding performance of Dendrocalamus latiflorus plantations on the central and bottom positions of slopes were significantly higher than those on the upper position of slopes.But in general,the soil water-holding ability of Dendrocalamus latiflorus plantations on different slope positions was better than that on the agricultural cropland.Therefore,as a main plantation species,Dendrocalamus latiflorus played an effective part in the function of water conservation and had a higher ecological benefit.But to order to get the better economic and social benefits,the effect of slope positions should be considered and the intensive management should be needed.
