广西漓江沿岸竹类资源调查

调查了漓江沿岸的竹类资源，发现两岸分布竹子7属37种、变种或变型，以箣竹属Bambusa居多，占竹种数量的45.9%；其次为刚竹属Phyllostachys，占21.6%。从竹子类型区分，丛生竹占62.2%，散生竹占37.8%。在两岸还发现木竹Bambusa rutila、狭耳坭竹B.angustiaurita、大绿竹B.grandis等多种广西濒危、特有竹种的分布。种植环境和利用方向对竹子的分布区域和种植量影响较大。多数竹林竹丛老化，竹蔸上浮，景观效果差。漓江景区的精华段——阳朔段两岸景观带主要由车筒竹B.sinospinosa、撑篙竹B.pervariabilis构成，环境卫生问题不容乐观。濒危、特有竹种保护可通过扩繁和开发新用途来实现。

Bamboo Resources Investigation along Lijiang River in Guangxi Zhuang Autonomous Region

The bamboo resources along the Lijiang River are investigated, and 37 bamboo species, varieties and forms of 7 genera are found on both sides of the river, in which those belong to Bambusa are dominant, accounting for 45.9% of the total, followed by those of Phyllostachys, accounting for 21.6%. In terms of bamboo types, the sympodial bamboo accounts for 62.2% and the monopodial bamboo accounts for 37.8%. Some endangered and endemic species in Guangxi such as Bambusa rutila, B. angustiaurita and B. grandis are also found on both sides of the river. The planting environment and utilization direction have great influence on the distribution area and the planting amount of bamboo. Most bamboo forests have a poor landscape with the aging bamboo and floating up stump. The landscape along Yangshuo section, which is the most beautiful and important one of the Lijiang River, is mainly composed of B. sinospinosa and B. pervariabilis, with a poor environment and hygiene. The protection of endangered and endemic bamboo species can be achieved by expanding propagation and developing new uses.
