ZHENG Li-feng1,ZHOU Xin-nian1,LUO Ji-zhang2,WU Mei-ling1,CHEN Zhen-lan1(1.College of Traffic,Fujian Agriculture and Forestry University,Fuzhou,Fujian 350002,China;2.Jian′ou Forestry Bureau,Jian′ou,Fujian 353100,China)  
Using aggregation index method,the effects of selective cutting of different intensity(low intensity,13.0%;middle intensity,29.1%;high intensity,45.8%;over-high intensity,67.1%) on the regeneration pattern of natural mixed stand of conifer and broad-leaved trees of northern Fujian were surveyed and analyzed.The results show that natural regeneration have a good state under selective cutting operation,and with the increasing intensity of selective,increased regeneration density.All the distribution patterns in the five dominant populations were clumped pattern regardless of selective intensity,but the assemble intensity and mean crowding index various trends.The results would do help to discuss the natural reproduction and provide a guide for natural forest management.
