【摘要】 通过对枣-麦间作系统、枣-草间作系统和小麦单作系统进行调查,发现3种系统的植物群落多样性指数的关系为枣-草间作系统(2.5265)>枣-麦间作系统(1.6615)>小麦单作系统(0.1890);相应的节肢动物群落也有相似的趋势,枣-草间作(3.0322)>枣-麦间作(1.7708)>小麦单作(0.1890)。还将3种样地的节肢动物群落划分为不同的功能集团分析了其多样性,发现3种样地功能集团之间的差异并不显著。更多还原

【Abstract】 Through the investigate of the arthropod community at three different dind ecosystem:the agro-forestry ecosystem、the jujube garden and the pure agriculture ecosystem.We find that the plant diversity index is change like this,the index of jujube garden is higher than the agro-forestry ecosystem and the agro-forestry ecosystem is higher than the pure agriculture ecosystem.The diversity indexes of the arthropod community at the three ecosystems have the similar change.更多还原
