摘要
对湖南湘潭锰矿矿业废弃地营造林的3．5-4．5年生栾树、杜英混交林进行了生物量研究．结果表明:林分密度为3 240株／hm2,栾树单株生物量为1 175-1 958 g,杜英为544-909 g;林分生物量为3125-5211．00 kg／hm2,林分净生产量为893．00- 2085．48 kg／(hm2·a)．现林木生命力强,生长旺盛,林分生产潜力大．为矿区废弃地的植物修复提供了优良树种．
The biomass of a 3. 5 to 4.5-year-old Koelreuteria paniculata mixed stand was studied on the abandoned land of a Xiangtan manganese mine. The result shows that the individual biomass in the mixed stand with density of 3 240 trees per hectare varied enormously： 175 to 1 958 g for Koelreuteria paniculata and 544 to 909 g for Elaeocarpus decipensi and that the stand biomass and the net production were 3 125 kg/hm^2 to 5 211.00 kg/hm^2 and 893.00 kg/（hm^2·a） to 2 085. 48 kg/（hm^2 · a） respectively. Now these trees have strong stems and grow healthily with great potentials. Therefore, this tree species was well chosen for the plant remediation of mine abandoned lands.
