本研究对北京山地白皮松造林进行了全面调查研究,结果表明,它在低山区造林表现良好,与乡土树种油松相比,它的根系深广,叶量丰富.通过PV曲线等生理指标的测定,证明它具较强的保水能力下口吸水能力,更大的生产能力,更好的绿化美化效果,因而是北京低山区造林的优良树种之一,建议大力推广. In this study, we conducted a comprehensive survey of the Pinus bungeana afforestation in mountainous area of ​​Beijing. The results showed that afforestation was good in low mountainous area, and its root system was broad and abundant in leaf area compared with Pinus tabulaeformis, a native tree species.By measuring the physiological indexes such as PV curve, Proved that it has a strong water retention capacity under the mouth water absorption, greater production capacity, better greening and beautifying effect, which is one of the fine tree species afforestation in Beijing low mountain area, it is recommended vigorously promote.
