中国竹乐器的现状及发展之我见

中国是世界上利用竹做乐器种类最多，同时也是在使用方面最普及和水平最高的国家之一。把众多的竹乐器组成一个高水平规模化的乐团应该说是一个创举，竹乐团独特新颖，色彩浓郁，会在文艺演出旅游、教育和群众文化中带来好处，尤其对竹的各种活动中更显必要。竹乐队的繁荣必然带来竹乐器制造业的繁荣，竹乐器加工是高附加值、较高技术含量的行业，是竹材利用的好途径，会给竹产区带来很好的经济效益     

毛竹产区山地扩鞭还林前景的的探讨

在富阳市毛竹产区存在大量曾作为产粮的山地，随着经济的发展，山区农民不再依赖这些山地解决粮食问题，而通过毛竹扩鞭还林不仅可以大大提高经济效益，而且也是生态建设发展的必然趋势，具有广阔的前景。

湿热环境下生漆涂饰竹木材的吸湿性变化规律

采用涂料涂饰的方法,使用生漆及其对照涂料桐油、水性漆对毛竹及其对照样材柞木、樟子松进行处理。在恒温恒湿箱模拟的湿热环境下,研究生漆及其对照涂料涂饰竹材、柞木和樟子松的吸湿性变化规律。研究表明,生漆涂饰竹材的防潮能力最强,水性漆涂饰竹材的防潮能力次之,桐油涂饰竹材的防潮能力最弱;生漆涂饰处理方法对毛竹的吸湿性影响最大,防潮能力最强,柞木次之,樟子松最差。     

竹在苏州古典园林中的造景应用研究

从魏晋时期、唐宋时期、明清时期3个阶段回顾了苏州园林植竹造景史,并选取拙政园、狮子林、网师园、沧浪亭等苏州古典园林,总结了其中的竹景。分析了苏州古典园林的竹景营造技法,重点围绕竹径通幽、禅悟体验,粉墙竹影、青竹白石,竹林听风、雨竹空濛,突出了竹景所营造出的诗情、画意、音韵。     

浙江余杭中泰乡竹笛产业区的变迁及发展研究

杭州市余杭区中泰乡从20世纪80年代开始制笛,至今已有近130家制笛企业,中泰乡制笛业的快速发展现象已引起了政府和专家的重视。该文通过实地调研,初步探讨了中泰乡竹笛产业区的发展特点和发展机制,认为偶然性、村民共同愿望、制度转型和政府支持是产业区发展的主要内在因素;同时指出了中泰乡竹笛产业区存在的问题并对今后的发展提出了一些建议。     

竹子在音乐领域里的运用

Development of structural composite products made from bamboo II: fundamental properties of laminated bamboo lumber

This experiment explored the technical feasibility of using bamboo zephyr mat with pre-hot-pressed treatment for the manufacture of laminated bamboo lumber (LBL), which is similar in construction to that of laminated veneer lumber (LVL). Six LBL boards (made from four-ply bamboo zephyr mats) with approximate dimensions of 2×42× 42cm were fabricated using resorcinol-based adhesive. The experimental design involved three combinations of layered structures (types I, II, and III) and two LBL loading positions (H-beam and V-beam) during the bending test. These materials were then compared to ordinary LVL. Results indicated that the bending properties (moduli of rupture and elasticity) of LBL were comparable to those of LVL, but there was no significant effect on the physical and mechanical properties among the three types of LBL beam. Interestingly, orienting the glue line to the vertical direction (V-beam) could maximize the ultimate strength of the LBL.Part of this research was presented at the 49th Annual Meeting of the Japan Wood Research Society, Tokyo. April 1999, and at the Pacific Timber Engineering Conference, Rotorua, New Zealand, March 1999

Growth behavior of Phyllostachys nigra var. henonis （Bambusoideae） in Central China

In the Shennongjia National Nature Reserve of Central China, the vegetative growth behavior of henon bamboo (Phyllostachys nigra var.henonis (Mitford) Stapf. ex Rendle) was studied from shoot recruitment to culm establishment. In May, bamboo shoots emerging from the ground achieved an average density of 2.7 shoots m⁻² during the sprouting phase of 16 days. However, about 32% of the new shoots died back before maturity. Insect damage, withering death and rodent predation were responsible for 57%, 29% and 14% of the total shoot mortality, respectively. From May to June, the shoots attained 400±23 cm during the height growth phase of 34 days, with a daily rate varying from 1 to 56 cm. All branches and leaves unfolded during the branch spreading phase from June to August. Shoot production was positively related to the density of standing culms, but negatively to both coverage and height of herb layers.
