This artical reviews that successive rotation of Chinese fir results in low amount of soil bacteria,fungi and actinomyces,in different distribution of microorganism species,especially fungi, in low soil enzyme activity,in less kinds of free amino acid and in low content of free amino acid and free sugar and free phenol,in low content of soil organic nutrient and available nutrient,espcially available phosphorus,compare with first rotation of Chinese fir at Kuocang Mountain of Lishui region in Zhejiang province. The research of infrared absorption spectrum also shows that the composition and structure of organic matter have obviously difference.The research results open reveal the relationships of yield dicline and variation of soil structure and composition.
