摘　　要：对不同经营目标毛竹林土壤物理性质及健康状况进行了研究与评价。结果表明,材用林的土壤含水率、各持水量指标及土壤密度均好于笋用林和笋材两用林;3种经营目标竹林土壤孔隙度各指标规律不明显。对3种经营目标竹林土壤物理性质健康状况进行评价,笋用林、笋材两用林、材用林关联度分别为0.604 7、0.650 8、0.752 3,表明材用林土壤健康状况最好,笋用林土壤健康状况最差。Physical property and health status of soil were studied and evaluated in bamboo forest under different management purpose. The results showed that the moisture content, the moisture capacity indexes and the bulk density of soil in bamboo-timber forest are better than those in bamboo-shoot forest and timber forest. Soil porosity in three different management purpose forests has no obvious regularity. The correlation degree values of soil health status in three different management purpose bamboo forests are 0. 604 7, 0.650 8 and 0.752 3. The health status of soil is the best in bamboo-timber forest and the worst in bamboo-shoot forest.
