摘要: 本文对四川蒲江县马尾松天然林采伐年龄进行了研究。试验选定Richard生长模型为马尾松天然林的基本模型,建立了胸径、树高、材积与年龄的生长模型,编制出马尾松生长过程表与林分出材率表,用现行木材价格计算木材收入,采用指率法进行经济分析确定出经济成熟龄。经与实行多年的马尾松天然林采伐年龄相比,其采伐年龄推迟10年左右。

Abstract: The cutting age of PIUNS MASSONIANA natural forest in Pujiang county of Sichnan Province was systematically studied. Richards function was selected as the basic model for growth estimation. The growth function of diameter at breast height, height of trees and volume were constructed with age as variable. Yield table and merchantable volume table were established. The income of cut was calculated by current timber price. Comparing the cutting age determined by traditional method, this cutting age is delayed about 10 years.

Key words: PIUNS MASSONIANA, GROWTH MODEL, FOREST MATURITY, CUTTING AGE
