Through the comparative analysis of the arthropod community between intercropping system and the three control systems～the weeding jujube yard system, not weeding jujube yard system and the system of farmland, it is showed that the intercropping system have a more richer neutral arthropod groups. Compared to Weeding jujube yard system and system of farmland the intercropping system have more advantages in natural enemies groups and more disadvantaged phytophagy groups. And the intercropping system can rebuild the arthropod community more faster than the other systems after the system was seriously disturbed, so it is than compared to other three systems the intercropping system have more proper structure and more stronger regulation ability and also more stronger ability to control pest.
