| 摘 要： | 本文研究了太行山草地植物生物量,结果表明,在4—9月生长季节中,禾本科、莎草科和豆科等牧草生物量7月份出现高峰值,鲜重799.68(公斤·亩~(-1),以下同),干重298.11。杂类草生物量8月份出现高峰值,鲜重466.74,干重122.60。半灌木9月份出现高峰值,鲜重46.85,干重18.79。总生物量7月份出现高峰值,鲜重1235.27,干重427.07。年平均生物量鲜重621.14,干重225.76。结果还表明,总生物量与气温、光照强度和土壤含水量呈正相关。

| Abstract: | The paper investigated the phyto-biomass of grassland in the Taihangshan Mountain.The data indicated that total phyto-biomass was 621.14kgFW · mu-1 and 225.76 kgDW · mu-1. Total phyto-biomass showed the peak in July in which fresh weight was 1235.27kg · mu-1, dry weight was 427.07kg · mu-1.The biomass of the feeding grass of the gramineae and cyperaceae and febaceae showed the peak in July,the biomass of the weeds showed the peak in August,the biomass of the shrub showed the peak in September. The total phyto-biomass had positive correlation with temperatune, light intensity and the moistrue of soil. |
