| 摘 要： | 为了研究水库生境扰动对藻类水华的作用机制,以中度扰动理论为基础,结合藻类群落生境选择学说和藻类生态功能组,开展了不同温度扰动周期、相同扰动幅度下藻类多样性变化特性和群落结构演替特征的室内控制实验.结果表明:1适度的扰动会促进藻类的生长且增加其多样性.中度扰动组Δ22℃/48 h藻类生物量最大,但多样性最高,不存在绝对占优藻种,而高频次扰动组Δ22℃/24 h生物多样性较小,但可降低藻类生物量.2温度的周期性变化对浮游藻类群落的演替有明显的影响,优势种也呈现一定的差异性.藻类优势功能组演替基本规律为:X_1(小球藻)→J(栅藻)→S_1(席藻)或X_2(衣藻),群落结构呈现出C/CR型藻类先行占优向R型演替的趋势.高温扰动频繁时,R型藻类(S_1)明显占优;无扰动或低扰动时,群落结构组成特点以C/R策略为主.适度的扰动组Δ22℃/48 h形成了多种生长策略的藻类共存的格局,且耐受高温胁迫的S策略藻类(L_0)开始出现.
