摘要
Ⅳ类地14年生闽粤栲萌芽林分生物量(地上部分)58.2t/hm2,其中乔木层生物量51.7t/hm2;林分年均净生长量5.582t/(hm2·a),其中乔木层年均净生长量3.693t/(hm2·a);林分平均胸径9.7cm,平均树高9.1m,蓄积量111.2m3/hm2,萌芽木株数占全林株数的78%;林分叶面积指数1.67m2/m2,叶对树干的净同化率203.6g/(m2·a).
The Castanopsis fissa sprout stand has high productivity, the 14-yeared stand (on site typeIV ) biomass is 58. 26t/hm2 (above ground ), the tree layer biomass is 51. 7t/hm2. The stand net productionis 5. 582t/(hm2. a), the tree layer net production is 3. 693t/(hm2. a ). The stand average DBH, height andvolume are respectively 9. 7cm, 9. 1in and 111. 2m/hm2.
