摘　　要：以四川华蓥山拟放归大熊猫区域的白夹竹(Phyllostachys bissetii)林为研究对象,运用单因素方差分析(one-way ANOVA)和生境适宜性指数(HSI)模型,探究采伐留养与施肥的经营措施对白夹竹生长状况和生境适宜性的影响。结果表明:研究区域内经营后的白夹竹生长状况比未经营好;实施采伐留养与施肥的样方主要是白夹竹的适宜生境,而未采取措施的样方则主要是白夹竹的一般适宜和次适宜生境。白夹竹对海拔、坡度这两个环境因子的适宜性变化具有明显的经营效果差异(P<0.05)。可见,华蓥山采取的采伐留养与施肥的经营措施明显改善了白夹竹的生长状况和生境适宜性,但仍需在以后的经营中注意对乔木、灌木的保护,合理调节林分密度,以期为白夹竹的可持续利用和大熊猫的野外放归奠定基础。The Phyllostachys bissetii forest where giant pandas will be releasedin Huaying Mountain was selected as research object,wes tudied the effects of cutting leaving and fertilization on the growth and habitat suitability of P.bissetii by using the one-way ANOVA and habitat suitability index model.The growing condition of the P.bissetii in management was better than that undisturbed.The suitable habitat of bamboo were the main constituents of the cutting leaving and fertilization quadrats,the undisturbed quadrats were mainly the general or sub-suitable habitat.The change of suitability of P.bissetii to altitude and slope was caused by management(P<0.05).It can be seen the management measures taken by HuayingMountain have significantly improved the growth condition and habitat suitability of the P.bissetii.However,we need to pay attention to pretect trees and shrubbery in the future,and reasonably adjust the stand density,expect to lay a foundation for the sustainable utilization of the P.bissetii,and release the giant pandas in the wild.
