摘要:在云南屏边大凹腰天然毛花酸竹林中选择中坡位、坡度12°-13°、坡向东南、土壤基本一致的林分,采用人工经营措施,进行林分复壮试验,观测人工经营对其林分结构的影响。结果表明:经过1 a的人工经营,立竹度变动幅度由124.73%降低至67.98%;老龄秆减少了4.63%,而幼龄秆增加了7.98%;平均胸径增长了1.9%;改造后整齐度提高到2.876,均匀度提高到3.942,达到了一般均匀林。
Analyze and compare the changes in stand structure of Acidosasa hirtiflora after experiment ,the stand was natural bamboo stand in Daoyao Pingbian Yunnan ,in the middle of the hillside ,faced southeast ,sloped 12 °to 13 °and with the same soil.The result show that rariations of culm density was reduced ,from 124.73% reduced to 67.98%,old culm dereeased 4.63% and young culm increased 7.98%,average diameter an breast height was improved 1.9%,regularity of stand structure was improved to 2.876 ,uni-formity of stand structure was improved to 3.942 and it was has been the nomal -even stand.
