%X A field experiment was conducted to investigate the effect of cassava-peanut intercropping on stability of the ecosystem, and also an association analysis was taken on soil moisture and pH value. The results showed that: (1) When total solar eclipse occurred, peanuts under intercropping measures showed a higher resistance to the environment than pure measures, reflecting the advantage of intercropping; When the total solar eclipse happened, the restoration of net photosynthetic efficiency(Pn) of peanut under pure measures increased, reflecting the net advantage. (2) With the model of leaf temperature, a concept named intercropping dominance (ID) was created. The ID of cassava-peanut intercropping derived +0.83% which verified that cassava-peanut intercropping really had advantages under normal weather conditions. (3)While improved the performance of water retention undoubtedly, cassava-peanut intercropping also exacerbated the red soil acidification.
