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.
