Study On Plant Diversity And Functional Traits In Cenwang Laoshan

Cenwang Laoshan Nature Reserve is located in the south subtropical zone.It has rich forest vegetation,obvious vertical lineage of vegetation and high scientific research value.It is an ideal place for ecological research.According to the forest dynamic plot operation standard of CTFS,five 1hm~2 plots were established in different elevation gradients in Cenwang Laoshan.Based on the investigation of five plots of different elevation gradients in Cenwang Laoshan,this study analyzed plant diversity,plant functional traits and their correlation with topographic factors,and reached the following conclusions:1.There were 52 families,147 generas and 389 species in 5 plots of Cenwang Laoshan,with high species richness.2.The diversity of forest community in Cenwang Laoshan was significantly negatively correlated with the altitude factor.The main topographical factors was the elevation.3.There was a significant positive correlation between plant height and DBH,and a significant negative correlation between leaf area and leaf dry matter content.Plant functional trait values(CWM)of dominant species were significantly correlated with elevation factors,and the CWM values of different species had different responses to altitude factors.
