栓皮栎种群的生物量与材积动态及其密度调节

以河南省广泛分布的栓皮栎种群为对象 ,通过对该种群在不同程度干扰下的生物量与材积进行Logistic模型模拟 ,说明了其增长与环境之间的关系 ;同时通过其密度调节的 - 3/ 2法则拟合 ,说明了种群能够保持其稳定性的机制。本文可以为栓皮栎种群的管理与保护提供依据

A study on the biomass and volume dynamic and the density regulation of Quercus variabilis population

Quercus variabilis , belonging to Fageceae, is widely distribted in the west montains in Henan province. But now it is decreasing in distributed area and population quantity, for the abuse and destroyment by mankind. This paper demonstrated that the biomass and volume increasement of Q.variabilis population has strong relationships with its environment, through the Logistic model simulation in deferent degree of disturbance. It also studied the mechanisms for the population maintains its stability, with the research of the population's density regulation. The conclusion can be a reference to the population's management and protection.
