摘要: 通过树干解析及样地实测资料拟合四川香椿生长模型,对四川省香椿的生长特性及栽培分区进行了研究。结果表明:香椿树高具有明显前期速生特点,5 a~12 a树高生长迅速,香椿树高生长速度盆周山地最快,川西南山地次之,盆中丘陵最慢。5 a~20 a,胸径生长速度较快,21 a~30 a胸径生长速度减缓,胸径平均生长速度川西南山地最快,盆周山地次之,盆中丘陵最慢。香椿材积在10 a~30 a生长迅速,四川香椿的材积生长潜力大,材积成熟年龄在20 a之后,材积平均生长速度川西南山地最快,盆周山地次之,盆中丘陵最慢。川西南山地较其它区域香椿生长状况最好,该地的宜林荒山发展香椿人工林前景广阔。本文重新划分了四川省香椿地理栽培区,目的是为定向培育四川香椿人工林提供科学依据。

Abstract: In this paper,the stem analysis and measured sample data were used to fit the Toona sinensis growth model in Sichuan Province and studies were made of Toona sinensis growth characteristics and cultivation zones in Sichuan. The results showed that the Chinese toona tree had obvious early fast-growing characteristics,from 5 years old to 12 years old its tree height growth was rapid.Chinese toons tree height growth rate was the fastest in mountain regions around the Sichuan Basin,the next in Southwest Sichuan mountain and the slowest in the hilly areas.In 5 years~20 years its DBH growth was more rapid,in 21 years~30 years its DBH growth slowed down.The average DBH growth rate in mountainous areas in Southwest Sichuan was the fastest,followed by mountainons areas around the Sichuan Basin,and was the slowest in the hilly areas.The toon a tree volume in 10 years~30 years showed a rapid growth.its volume mature age happened after 20 years.Its volume average growth speed in southwest mountainous regions of Sichuan was the fastest,followed by the basin mountain,and was the slowest in the hilly areas.In Southwest Sichuan mountain areas,the growth of Toona sinensis was the best.Toona sinensis plantation in the barren hills had broad development prospects.In this paper,the cultivation areas of Toona sinensis in Sichuan were redivided,aiming to provide scientific basis for oriented cultivation of plantations.
