摘　　要：用剪纸称重法实测茶杆竹各径阶标准竹叶面积，竹子叶面积与直径成直线回归关系，回归方程为：ｙ＝３８５５３．９７＋６１９４．９３ｘ，根据该方程计算可列出茶杆竹直径与叶面积关系表，从而可计算林分叶面积与叶面积指数。Weighing of each diameter grade Pseudosasa amabilis leaf area was carried out by paper-cut method. The relation between the leaf area and diameter was linear regression. The regression equation of P. amabilis leaf area was Y=38553.97+6194.93X. This equation could arrange correlation between diameter and leaf area in tables thus calculating the stand leaf area and leaf area index.
