摘要: <正>对次生福建青冈林的组成数量特征及生产力进行研究。结果表明,江西次生福建青冈林乔木层优势种重要值福建青冈为6304,木荷为3992,石栎为3268;乔木层树种多样性ShannonWiener指数为23~42,群落均匀度为62%~87%,生态优势度为008~033;灌木层ShannonWiener指数为36~44,群落均匀度为92%~97%;草本层ShannonWiener多样性指数为04~14,群落均匀度为41%~86%;林分蓄积生长量为284~430m3/hm2.a。

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.
