摘要
对滨海盐碱地23年生刺槐纯林和4种混交林内刺槐生长规律进行研究,结果表明:刺槐的树高、胸径、材积生长均以刺槐白蜡混交林表现最好,明显高于刺槐臭椿行状混交林、刺槐臭椿块状混交林、刺槐榆树混交林、刺槐纯林林分。对刺槐材积生长进行Logistic曲线、S曲线、指数函数、对数函数和幂函数数学模拟结果显示:滨海盐碱地不同组成的刺槐林分内,刺槐材积生长规律不能用单一的曲线模拟。
The growth rules of 23 year seedling black locust(Robinia pseudoacacia) in 5 stands on coastal saline-alkali soil was studied through the analysis on their height diameter at chest height and volume.The result showed that the difference of growth of black locust in 5 stands was significant.The growing state of black locust was the best in mixed forest of black locust and Chinese ash(Fraxinus chinensis),the growth of height diameter at chest height and volume were better than the others.Discuss the growth of volume in 5 stands with regression analysis of Logistic S Exponential Logarithmic and Power,the result shows that growth of volume in 5 stands need not only one curve to reflect.
