摘  要：
【目的】针对川西林盘受到破坏、植物群落稳定性减弱等现状,开展干扰强度对川西林盘木本植物多样性的研究,为提出川西林盘的保护和合理利用提供依据。【方法】以成都市城乡建设委员会绘制的成都市林盘分布图为基础,根据分布,采用样线法选择了183个典型川西林盘,利用现场调查开展研究。【结果】①从物种数量比例看,乔木占比高于灌木,拥有较大的生长空间,在人为干扰下依然保持着优势。②从干扰程度与植物占比的相关性表明:人为干扰程度与乔木占比不显著,人为干扰程度与灌木占比呈正相关关系,乔木占比与灌木占比呈负相关关系。③在控制了灌木与乔木间的交互影响后,则表现为人为干扰对乔木占比呈正相关;控制乔木占比这一变量,对相关性的结果影响不大。【结论】乔木是林盘的主要物种,并占据主导空间;人为干扰有助于乔木和灌木等木本植物在川西林盘中的分布。

摘  要：
【Objective】Aiming at the current situation of human damage and weakened plant community in the Linpan of Chengdu plain, the interference intensity was studied on the diversity of woody plants in the Linpan of Chengdu plain, which provided a basis for the protection and orderly utilization of the Linpan of Chengdu plain.【Method】Based on the distribution map of Chengdu forest tray drawn by Chengdu Urban and Rural Construction Committee, according to the distribution, 183 typical Linpan of Chengdu plain trays were selected by the sample line method, and the field investigation was used to conduct research. 【Result】(i) The proportion of species was higher than that of shrubs, which had a large growth space and still maintained advantages under human interference.(ii)The correlation between the degree of interference and the proportion of plants showed that the degree of human interference was not significantly higher than that of arbor, and the degree of human interference was positively correlated with the proportion of shrubs. The proportion of arbor and shrub was negatively correlated.(iii)After controlling the interaction between shrubs and trees, it showed that human interference was positively correlated with the proportion of trees; therefore, controlling the arbor ratio was not a big influence on the correlation results. 【Conclusion】Trees were the main species of Linpan of Chengdu plain and occupied the dominant space; human interference contributed to the distribution of woody plants such as trees and shrubs in the Linpan of Chengdu plain.
