In this paper the authors make a review on advances on researches of interspecific nutrient interaction of mixed forest ecosystems. Studies show that mutual influence among species of mixed forest ecosystems change the component, quantity, quality of above and below ground litters; their decomposition, nutrient release processes are different from pure forest ecosystems; and also, soil nutrient level, efficiency and utilization ratio in the former ecosystems are higher than the latter. The interspecific nutrient relation among reasonable blended mixed forest ecosystems can come up to be mutually beneficial and harmonious by means of space time nutrient absorbing difference and nutrient transfer between tree species in these ecosystems. Finally, problems in researches on interspecific nutrient interaction among mixed forest ecosystems are probed.
