中国杨树人工林培育技术研究进展

我国杨树人工林总面积达700万hm²，位居世界第一.发展杨树人工林、满足社会经济发展和环境保护的需要是世界杨树研究的发展趋势.在介绍中国杨树栽培区区划、杨树人工林的主要栽培无性系及其生产力的基础上，总结了近10年来我国杨树在立地质量评价、苗木培育技术、人工林定向培育模式、混交林营造技术、林农复合经营技术、人工林水分和养分管理技术、立地生产力维护和杨树人工林的生态功能等方面的研究进展，讨论了我国杨树人工林的生产潜力、杨树人工林的布局、杨树人工林定向培育及加强杨树人工林的环境功能研究等问题，为我国杨树人工林资源的培育及可持续经营提供参考.

Silviculture of poplar plantation in China: A review.

There are more than 7.0 million hm² of poplar plantation in China, ranking top one in the world. To meet the needs of a growing world for social-economic development, environmental improvement, and sustainable development through poplar plantation establishment is a main research interest in the globe. This paper introduced the regionalizing cultivation, key planting clones, and productivities of poplar plantations in China, and summarized the recent 10 years research progress in China in the site quality evaluation, seedling propagation techniques, management patterns, mixed plantation establishment, agroforestry management system, water and nutrient management techniques, site productivity maintenance, and ecological functions of poplar plantation. The potential productivity, general allocation, oriented silviculture, and environmental function study of poplar plantation were also discussed and prospected. The contents of this paper would provide some references for the silviculture and sustainable management of poplar plantation in China.
