Abstract: Study results indicate: Tylenchulus semipenetrans distribution in Fujian Province widely,but the damage is very serious in Shuncang,Nanping,Jianyang,and Sa County,etc. The natural distribution of the nematodes is notably related to soil texture,slope trend,tree age,etc. In light soil,sandy soil,or young growth,middle aged growth or shade slope,the nematodes has a big distribution. No matter what the ecology factors are,the most nematodes distribute in 0~40 cm depth soil. The age of Cunninghamia lanceolata has notably effect on the vertical distribution of the nematode,so has soil texture and the slope trend.
