On the basis of field investigation of a 1 600m² plot,We analyzed physiognomy,structure,the floristic composition and species diversity of a Rhodoleia championii community in Donguan Yinpingshan Forest Park,Guangdong. There were 153 vascular species,belonging to 116 genera and 73 families. Trop. & Subtrop. elements were the dominant. The community was mainly dominated by Rhodoleia championii. The vertical structure of the community was composed of Tree layer,shrub layer,herb layer and rich interstater plants,and dominated by evergreen plants in Microphanerophytes. According to the Raunkiaer Frequency Law,species in 1-20% occurrence frequency dominated the community,accounting for 67.97% of the total species. Because of the human interference,the number of the Saplings and young Rhodoleia championii trees was less,which indicates the population was on the declining trend. The different diversity indices showed different trend among layers in the community except that the shrub layer had the highest diversity.

Based on the difference analysis and statistical comparison with number,basal diameter and height of Bashania bamboo shoots and bamboo stems between the 1^st and 2^nd year(s) after strip thinning in Bashania Fargesi forest, it is shown that strip thinning can change the internal structure of B. Fargesi forest and increase the number of bamboo shoots and stems,and make bamboo regeneration occurr first. The effects of strip thinning will decrease with time. The effects on the basal diameter and height of both bamboo shoots and stems occurr in the second year after strip thinning. It is obvious,to some extend,that strip thinning can ease bamboo aging and quality deterioration,and finally attain rejuvenation.

In this paper,the undergrowth plant diversity of Cunninghamia lanceolata pure forest,and its three types of mixed forest with 3 species of broadleaved trees in Jian’ou,Fujian province were studied. The results showed that the abundance and Shannon-wienner indexes in all three types of mixed forests were described as shrub layer >herbaceous layer. Except that of Cunninghamia lanceolata×Liriodendron chinense,the Simpson indexes of the 2 other types of mixed forest were greater in the herbaceous layers than that of the shrub layers,Pielou indexes were greater in the shrub layers than the herb layers. The undergrowth plant species of mixed forest was smaller,the dominant species were obvious,and the distribution was uneven. The distinction of four kinds of diversity indexes measured in the different mixed forests was not obvious. Compared with the mixed forest,the difference of all indexes in the pure forest were not significant. The results would help to improve the cultivation and management of Cunninghamia lanceolata and its mixed forest in northern Fujian province,and eventually realize the sustainable management of the Cunninghamia lanceolata forest.
