摘要:
为了研究刺槐在不同恢复模式中的数量特征和格局分布，选择复垦17 a的SⅢ样地（刺槐×榆树×臭椿）和SⅤ（刺槐纯林）两块固定监测样地，对比两样地中刺槐的径级结构、枯梢个体的格局和入侵物种的特征等。结果表明：（1）SⅢ样地中刺槐存活率和存活个体的平均胸径比刺槐纯林要高；（2）由于竞争关系的存在及水分等环境因子的影响，SⅢ样地和SⅤ样地刺槐不同径级个体的空间分布表现出一定的空间异质性。（3）枯梢与刺槐栽种的密度和所处的位置有关，受风较多的SⅤ样地枯梢严重，背风的SⅢ样地枯梢树木明显少于SⅤ样地。
Abstract:
In order to study the numeric character and spatial pattern of Robinia pseudoacacia L. under two kinds of recovery modes, SⅢ and the SⅤ plots after 17 years of reclaiming were choosed as study area. The size-class distributionm, the shoot blight individuals of Robinia pseudoacacia L. distribution and the character of invader species were comparied. The results were obtained as following: (1) the survival rate and the number of alive Robinia pseudoacacia L. individuals at the configuration mode of locust+elm+ ailanthus were higher than the configuration mode of Locust pure forest; (2) due to the existence of the relationship between competition and some environmental factors such as water, the space distribution of Robinia pseudoacacia L. in different diameter classes at SⅢ and SⅤ plots showed different spatial heterogeneity; (3) the shoot blight was related to the plant density and position of Robinia pseudoacacia L., and the shoot blight in SⅤ plot was obviously more serious than that in SⅢ plot, because of the wind.
