1、14.4 群落的演替【基础知识填空】1、演替:随着时间的推移,一个群落被另一个群落 的过程。2、初生演替(裸岩等)的过程: 次生演替(弃耕农田等)的过程: 3、人类活动往往会使群落演替按照不同于自然演替的 进行。【巩固练习】1、有关初生演替和次生演替的叙述,正确的是( )A沙丘、火山岩上进行的演替是初生演替,冰川泥、弃耕农田上进行的演替是次生演替B初生演替形成的群落内无竞争现象,次生演替形成的群落内竞争明显C初生演替所需时间较长,次生演替所需时间较短D初生演替能形成森林,次生演替很难形成森林2、下列不属于初生演替的是( )A弃耕农田上进行的演替B火山岩上进行的演替C冰川泥上进行的演替D沙丘上进

2、行的演替3、下列关于森林群落垂直结构的叙述,错误的是( )A群落中的植物具有垂直分层现象B群落中的动物具有垂直分层现象C动物在群落中的垂直分层与植物的分层有关D乔木层的疏密程度不会影响草本层的水平结构4、根据群落演替的理论,在光裸的岩地上经过一定的时间,最终就会演替出森林。请据此回答问题:(1)光裸的岩地上最终演替出森林,其过程大致是_。(2)地衣首先在裸岩上定居,同时,地衣分泌的_腐蚀了坚硬的岩石表面,加速了岩石风化成_的过程。(3)各种昆虫及其他小动物开始进入生物群落的阶段是_。2(4)地衣阶段与苔藓阶段相比,土壤中的有机物含量较多的是_,微生物种类较多的是_。(5)在以下演替的各阶段中,所需时间最长的是_,所需时间最短的是_。A地衣和苔藓阶段B草本植物阶段到灌木阶段C灌木阶段到森林阶段D森林阶段
