枣粮间作系统节肢动物群落结构动态

In this research the Jujube-grain ecosystem have been divided into to sub-ecosystem and the investigation about the total individual numbers and species numbers of the arthropod community have been done in each sub-ecosystem, they diversity index have been analyzed as well. Three kind of other ecosystems: pure farm ecosystem, weeding jujube garden ecosystem and jujube garden ecosystem was used as comparison systems. The result show that individual numbers and species numbers of jujube sub-ecosystem and jujube garden ecosystem is much higher than other systems. And the jujube sub-ecosystem have more neutral arthropod individual and species. There were same trend between farm sub-ecosystem and pure farm ecosystem. The result also show that the weeding jujube ecosystem and pure farm ecosystem was easily to have a break out of phytophagy arthropod group compare with jujube sub-ecosystem and farm sub-ecosystem respectively.
