| 摘 要： | 为了促使北京山区油松人工林向发挥多功能目标的森林结构转变,在近自然森林经营理念和技术指导下对西山地区51年生的油松人工林进行改造,并于2005年调查和设计,2006年初完成近自然森林改造的第1次作业.对固定观测样地的调查结果表明:经过近自然化改造,样地的Shannon-Wienner指数分别从0.121 7、0.940 4提高到0.917 4、1.492 1.油松林的林下更新层物种变化较大.大叶白蜡、栾树、构树等树种的天然更新,再通过播种补入栓皮栎,提高了林下更新的数量和质量.相对于未进行近自然化改造的林分,改造过的油松林,林木年生长量较高,林分结构得到了改善. |
| 关 键 词： | 油松人工林 近自然化改造 经营效果评价 林分结构 林分更新 |

| Abstract: | Pinus tabulaeformis plantation is one of the popular forest types in mountainous area in Beijing. However,the ecological service functions are difficult to be realized because of its simple stand structure,single tree composition,less understory vegetation,and low biodiversity. To make P. tabulaeformis plantations mentioned above develop towards the multifunction forest structure,a transformation experiment under the guidance of close-to-nature forest management was carried out in 51-year-old P. tabulaeform... |
