刺槐主伐利用后形成的多代萌生林给当地生态系统带来严重的危害。本研究针对刺槐萌蘖扩散控制的理论与技术需求，以刺槐为优势树种的林分为对象，采用SSR荧光标记和生态场理论和技术，结合采用原位观测与模拟试验相结合的方法，分别从个体、种群和群体的尺度研究刺槐萌蘖扩散的格局、过程与形成机制。群落尺度上分析刺槐萌蘖种群在不同林分类型中的萌蘖更新分布格局，确定其萌蘖扩散范围以及对乡土树种的影响；个体尺度上重点研究个体伐除后，不同萌生代数，以及同一代不同年龄刺槐的萌芽更新、根蘖更新的空间格局与过程；通过萌蘖更新与温度、土壤养分、光等生态因子场的相互作用关系分析，阐明萌蘖更新与其多维生态因子场的响应与作用机制；采用人工模拟试验的方法，研究揭示刺槐萌蘖发生的临界生态阈值。目的是为遗产地、风景区、森林公园等的刺槐林生态调控提供理论依据。该研究丰富和完善了森林更新、入侵植物防控的理论。

Multiple generation coppice forest of Robinia pseudoacacia after final cutting has caused serious harm to native ecosystem. Aiming at the requirement of theory and technology for controlling sprouting regeneration and dispersion of Robinia pseudoacacia, this study will resarch the dipersal pattern, process and formation mechanism of sprouting regeneration of Robinia pseudoacacia from individuel, population to community scale in the stands dominated by Robinia pseudoacacia by SSR fluorescence marker and ecological field theory and technology in-situ observation combined with simulation experiment. From community scale, distribution pattern of sprouting regeneration of Robinia pseudoacacia in different forest type will be analyzed so that the dispersal range of sprouting regeneration and the effect to native tree species will be determined.From individuel scale, spatial pattern and process of sprouting regeneration and root suckers regeneration were surveyed in coppice of different felling cycle or different age tree in same felling cycle after tree removal. The reponse and action mechanism between sprouting regeneration and multiple ecological factor field will be illustraed through the analysis the action relationship between sprouting regeneration and ecological factors such as such as air temperature, soil nutrients, solar radiation, etc. Finally,the ecological threshold of stump sprout and rootsucker formation will be explored by artificial simulation experiment. The purpose of this study is to provide theoretical basis for ecological control of Robinia pseudoacacia plantation in Heritage Site, scenic spot, national forest park, etc.. This research enriches and perfects the forest regeneration and invasive plant control theories.
