| 摘 要： | 文章实地调查了大娄山山脉金佛山方竹的垂直分布，并探索其在低海拔异地发展的可能性。2008年至2020年，以单竹丛为单位，对栽种在海拔2 000、1 356、1 352、1 130、1 080、720和658 m的金佛山方竹出笋情况进行逐年观测，比较其笋产量及笋营养元素含量与原生地的差异。结果表明：1）大娄山脉金佛山方竹天然资源主要分布在大娄山山脉海拔1 600~2 200 m，上线海拔2 227 m （柏芷山），下线海拔1 400 m左右，每年自然繁衍海拔下延1~3 m，个别植株通过山体滑坡及沟谷流水瀑布等外力带至海拔1 350 m或1 150 m处，并小面积蔓延；2）在海拔1 356~658 m的原生地低海拔区及异地引种金佛山方竹，除海拔658 m处的笋产量和氨基酸含量低于原生林外，其他引种地的笋产量和笋品质指标均与原生林差异不大。研究结果表明，通过选择优良单株，可以在海拔658 m以上沟谷背阴地的疏林下发展金佛山方竹。

| Abstract: | The paper investigates the vertical distribution of Chimonobambusa utilis in the Dalou Mountain Range and explores its development possibility at low elevations. The shooting of single Ch. utilis clump at altitudes of 2 000 m, 1 356 m, 1 352 m, 1 130 m, 1 080 m, 720 m and 658 m has been observed from 2008 to 2020 to compare the difference of the shoot yield and nutrient contents between them and the origin forests. The results show that: 1) The natural Ch. utilis resources are mainly distributed at altitudes of 1600-2200 m along Dalou Mountain Range, with the upper line at 2 227 m (Baizhi Mountain) and the lower line at about 1 400 m. They naturally propagate every year, and extend downward 1-3 m. Individual plants have been extended downward to 1 350 m or 1 150 m by external forces such as landslides, gullies, streams and waterfalls, and spread in a small area; 2) Except that Ch. utilis at 658 m has lower shoot yield and amino acid content than its original forest, the other bamboo forests at the altitudes from 658 m to 1 356 m have the similar shoot yield and quality with the original forest. The results show that Ch. utilis could grow under the sparse forest in the valley and shade place above 658 m. |
