摘　　要：中国西南喀斯特石漠化地区是中国严重的生态脆弱区之一,开展对石漠化的治理是西南喀斯特石漠化地区环境保护的当务之急。试验以重庆市岩溶石漠化山地为研究对象,依据石漠化生态环境脆弱的特点,结合石漠化生态恢复治理中环境造林的原则与要求,选择生物学特性表现为适应性强、阳性速生、耐旱、耐贫瘠、适合在喀斯特石漠化山地生态恢复治理中种植的先锋植物山桐子为造林树种,具体介绍了山桐子在石漠化治理中的造林技术,从而为岩溶石漠化山地的植被恢复及生态重建提供造林经验及技术支撑。The Southwest Karst rocky desertification was one of the serious ecology frail region in China.To prevent and control the rocky desertification was important for the protecting of the environment.Taking Chongqing Karst rocky desertification mountain region as the object of study,according to the characteristics of the ecology environment in rocky desertification frail region,combining the principle and the request of afforestation,selecting Idesia polycarpa Maxim as the afforestation trees,the afforestation techniques was introduced in order to provide afforestation experience and techniques for the ecology resume and reconstruction in rocky desertification mountain region.
