Abstract:

【Objective】 To investigate the characteristics of Rhus typhina L. and its root sucker seedlings in different urban green space systems in the hope of providing a theoretical basis for the management and control of Rhus typhina L. 【Methods】 Rhus typhina L. and root sucker seedlings in different green space systems in Urumqi and Korla were taken as research objects, and standard plot method, standard row method and standard plant method were used to conduct investigation according to the actual planting situation. 【Results】 The growth of mother plant and root suckers of torch tree in Korla City was better than that in Urumqi City, and the root suckers of Rhus typhina L. in roadside green belt were the strongest; In all types of green space systems, the root suckers of Rhus typhina L. were clustered and mainly distributed within 1.5 m from the mother plant. The survivorship curve tended to be Deevey -II type, and the mortality rate of root suckers of Ⅲ - Ⅳ age classes was higher.【Conclusion】 Through time series prediction, it was found that the overall number of root suckers and seedlings of the Rhus typhina L. showed a decreasing trend.

Key words: urban green space system; Rhus typhina L.; root suckers; spatial distribution pattern; population dynamics

摘要:

【目的】分析不同城市绿地系统中火炬树及其根蘖苗特性,为火炬树的管理与控制提供理论依据。【方法】以乌鲁木齐市和库尔勒市不同绿地系统中的火炬树及根蘖苗为研究对象,采用标准地法、标准行法和标准株法进行调查。【结果】库尔勒市火炬树母株及根蘖苗生长优于乌鲁木齐市,路边绿化带中火炬树根蘖能力最强;各类型绿地系统中火炬树根蘖苗呈现聚集分布,且主要分布在距母株1.5 m范围内,存活曲线趋向于Deevey-Ⅱ型,且Ⅲ~Ⅳ龄级根蘖苗死亡率较高。【结论】火炬树根蘖苗数量总体呈现下降趋势。
