  china fir
The charcoals derived from four other wood species showed maximum ESE values of 28?dB for Japanese cedar, 23?dB for China fir, 32?dB for red oak, and 38?dB for Taiwan acacia, respectively, at a carbonization temperature of 1100°C.
      
The wood species used in this study were Japanese cedar, China fir, western hemlock, red oak, fortune paulownia, and Taiwan acacia.
      
Furthermore, the tool geometries of 40°/5°, 50°/15° and 60°/25° produced more flow chips (weight percentage) by end-grain milling of China fir and maple.
      
The tool geometries of 40°/15° (sharpness of the angle-rake angle), 50°/15°, and 60°/15° for China fir and 40°/25°, 50°/5°, and 60°/5° for maple produced relatively more flow chips with parallel-to-grain milling.
      
The flow and thin chips were generated most often (on a weight percentage basis) for all tool angles investigated for parallel-to-grain and end-grain milling of China fir and maple.

Longitudinal stem analysis on correlation between early growth and late growth was made of over sixty China firs collected from nine main production centers in Hunan. Results indicate that: (a) It is possible to early predict the fast-growing performance of China fir. The correlation coefficients of diameter growth and height growth between 3-to 4-yr-old trees and 20-yr-old trees are significant(α=0.01 and α=0.001, respectively). (b) During the initial growth stage, if the selection differential...

Longitudinal stem analysis on correlation between early growth and late growth was made of over sixty China firs collected from nine main production centers in Hunan. Results indicate that: (a) It is possible to early predict the fast-growing performance of China fir. The correlation coefficients of diameter growth and height growth between 3-to 4-yr-old trees and 20-yr-old trees are significant(α=0.01 and α=0.001, respectively). (b) During the initial growth stage, if the selection differential is 20% in height, there will still be gains of 10% when the trees attain the age of twenty yr; and if the selection differentials are 50% in height and over 20% in diameter, gains of about 20% in height and diameter, and of over 50% in volume will be achieved at 20 yr old. (c) Different sites and production areas have a marked effect upon early predicting.

本文以湖南省九个杉木主要产区县的60余株树干纵向解析木为材料,进行生长量的相关分析。结果表明:(1)杉木速生性早期预测是可能的。8—4年生与20年生直径与树高的相关系数可达α=0.01和×=0.001的显著水平;(2)在生长早期按树高为20%的选择差选择,到20年生时仍保持10%左右效益。如树高按50%、直径按20%以上的选择差选择,到20年生时,树高和直径均保持20%左右效益,材积可获得50%以上效益;(3)不同的立地条件及产区,对杉木的速生性早期预测有着明显影响,在进行早期预测时,必须注意这些特点。

The low mountain area belongs to surplus of Tianmu mountain system. It is about 2000 square kilometres.We studied three major soil types i.e. the mountain natural soil, foot mountian natural soil and hilly cultivated soil.1) The mountian natural soil is mainly distributed on mountain slopes 80~180 m above sea level. The major soil formation is brown earthering process, and the accessary soil formation is a weakly allitic process. So, we can name the soil a yellowish-brown earth. This soil is suitable for growing...

The low mountain area belongs to surplus of Tianmu mountain system. It is about 2000 square kilometres.We studied three major soil types i.e. the mountain natural soil, foot mountian natural soil and hilly cultivated soil.1) The mountian natural soil is mainly distributed on mountain slopes 80~180 m above sea level. The major soil formation is brown earthering process, and the accessary soil formation is a weakly allitic process. So, we can name the soil a yellowish-brown earth. This soil is suitable for growing pine, China fir, bamboo, oak and Chinese sassatras, etc..2) The foot-mountain soil is located at the foot of a mountain.It is shown that the soil has lost Si and accumulated Al, Fe. But this process is not very intensive. The hydro-ferric-oxide content is dominant in soil profile,so this soil may belong to a yellow earth. It is extremely suitable for developing Chinese chestnut, common jujube, apricot, etc..3) The hilly cultivated soil is widely distributed on hilly land. It′s basic soil formation is allitie process, but it has got a cultivated process. Thus,we call this soil a cultivated yellow earth. The soil is extremely suitable for developing economic trees such as tea, oil camellia and tung oil.

苏浙皖边界低山丘陵区属天目山系余支,总面积约2000平方公里。本文研究了该区主要三种地带性土壤。山地自然土壤主要分布于海拔80—180米以上的山坡地,其形成以棕壤化为主,附加有弱富铝化过程,故拟称之谓黄棕壤。该土最适宜于生长松、杉、栎、檫木等优质树种和经济林毛竹。山麓自然土壤分布于山麓部位,脱硅及富铝化过程已很明显,但比较微弱,故拟定为黄壤。该土最适宜发展板栗、枣树和青梅等干果。丘岗耕作土壤广泛分布于丘岗部位,其形成是在富铝化过程的基础上,附加了耕作熟化过程,故拟定为耕型黄壤。该土最适宜发展诸如茶,油茶等经济植物。

Comprehensive experimental methods of the small forested catchment for studying China fir plantation ecosystems have been developed over the past five years by the Forest Ecosystem Research Station of the Central-South Forestry College. It has been methodologically inquired into that the forest ecosystem is defined as a small forested catchment with recognizable and controllable boundaries, and enclosing technique of the catchment is adopted and instruments are fully installed, so that the input, redistribution and output of nutrients in the system should be precisely determined, and physical and chemical problems in the forest hydrological processes elucidated. Some data have been used for analysis and contrast. The methods and techniques can be made use of for the setting up of forest ecosystem research stations in the mountainous areas of South China.

本文论述了中南林学院近五年来建立森林生态系统观测站,开展杉木人工林生态系统研究的方法——小集水区径流场综合实验法。从方法论上探讨了把森林生态系统定义在小集水区可辨和可控边界条件下,辅以径流场封闭技术和实验设施,从而准确测定系统内各种营养物质的输入、再分配和输出,以及森林水文学过程中的物理和化学等方面的问题。并用部分实验数据作了对比分析和验证。为南方山区建立森林定位观测站提供了借鉴。
