Keyword原生演替 生态位 普遍重叠 特定重叠
Abstract本义探讨了贡嘎山东坡泥石流扇形地植被原生演替不同阶段植物生态位重叠指数的动态变化,测计了不同优势种在原生演替进展中的数量化特征。初步研究了演替过程和机制。原生演替最初43年普遍重叠方面是完全的,以后逐渐减弱,原生演替在最初两年种对间特定重叠完全。以后重叠的种对数数目减少,82年时的植物群落中普遍重叠和特定重叠指数最低。种间生态相似程度决定种群动态和演替进程的重要因素之一。
Other AbstractThis study was carried out at the debris flow fan in the Huangbengliu gully on the cast slope of Gongga Mountain. Populations density, height growth, and total basal area in the vegetaion prmary succession, as well as the interrelationships among them and with the environmental conditions, had been surveyed. The paper dealed with the relationship between populations dynamics and miche overlap in the vegetation primary succession. The research results showed that the general overlap was complete during first 1-43 years, and was very high during 44-82 years in the primary succession. The specific overlap overlap was complete during the first 1-2 years in the succession. In the following, there had been a decrease in the specific overlap of the succession grasually. The general overlap and specific overlap is the fewest in the climax.
