| Abstract: | The quantitative characteristic of the composition and productivity of the Secondary Cyclobalanopsis chungii stand were discussed in this paper.The result showed that the dominant species' importance value of Cyclobalanopsis chungii,Schima superba,Lithocarpus glaber were 63.04,39.92,32.68 respectively;in tree layer,the diversity ShannonWiener index was from 2.3 to 4.2,the community evenness was from 62% to 87%,the dominance was in the range between 0.08 and 0.33;in the shrub layer,the diversity ShannonWiener index was in the range from 3.6 to 4.4,the community evenness was from 92% to 97 %;in the herb layer,the ShannonWiener index was 0.4 to 1.4,the community evenness was from 41% to 86%;the annual average volume increment of stand was from 2.84 to 4.30m3/hm2. |
