Abstract:

选取腾格里沙漠南缘景泰点(JBDZ)、古浪点(GMLT)和民勤点(MQQF)及对照点兰州(LZNS)天然分布的唐古特白刺克隆种群,结合统计检验和分形理论分析研究唐古特白刺克隆分株生长格局及枝系构型的环境异质性。结果表明,唐古特白刺表现出较为明显的形态可塑性,克隆分株存在显著差异,随着水分梯度递减,分株间距逐渐增大,对照点LZNS分株各指标普遍高于沙漠南缘三地,分株克隆生长格局呈现密集型,MQQF分株克隆生长格局有一定的游击趋势。克隆整合使得唐古特白刺克隆种群枝系构型表现复杂,LZNS的各级分枝角最小,MQQF最大;枝径比波动大,LZNS各级枝径比普遍最大,MQQF最小;LZNS唐古特白刺克隆植株总体分枝率和逐步分枝率均显著高于MQQF,但与JBDZ和GMLT差异不大;枝系分枝强度和各分维数表现较为一致,均以LZNS较大,沙漠南缘三地则表现出随水分梯度递减,白刺克隆植株分维数逐渐下降,枝系的空间格局趋于简单。研究表明在水分条件差的生境,唐古特白刺克隆种群获取资源的主要对策是,分株间距增加,分枝角度加大,而分枝强度变小,克隆生长格局趋于游击型,利于基株跨越和逃离逆境以获取水分。
