摘要
以呼和浩特市赛罕区典型乔木林为研究对象,分别在小钻杨(Populus×xiaozhuanica)和旱柳(Salix matsudana)纯林内设置样地,调查小钻杨和旱柳的生长状况、不同器官的生物量,及林下草本植被的生物量,并测定不同器官的碳含量,以期为研究区典型乔木林碳储量计算和评价提供参考.结果表明,小钻杨和旱柳的不同器官生物量变化趋势相同,均表现为干>根>枝>叶,小钻杨单株平均生物量为(29.66±2.14)kg,旱柳单株平均生物量为(16.68±1.36)kg.小钻杨林下草本层平均生物量为(14.45±1.58)g.m-2,旱柳林下草本层平均生物量为(15.89±2.36)g.m-2.小钻杨各器官碳含量在45%～52%,旱柳各器官碳含量为44%～53%.赛罕区2011年营造的23.5 hm2乔木林可产生的温室气体减排量约为999.99 t CO2当量,其中小钻杨林为602.01 t CO2当量,旱柳林为397.98 t CO2当量.
Abstract
Taking the typical arbor forest in Saihan District of Hohhot as the research object,the sample plots were set up in pure forests of Populus×xiaozhuanica and Salix matsudana,respectively.The growth status of Populus×xiaozhuanica and Salix matsudana,the biomass of different organs and the biomass of understory herbaceous veg-etation were investigated,and the carbon content of different organs was determined in order to provide reference for the calculation and evaluation of carbon storage of typical arbor forests in the study area.The results showed that the biomass of different organs of Populus×xiaozhuanica and Salix matsudana had the same change trend,which was trunk>root>branch>leaf.The biomass per plant of Populus×xiaozhuanica was(29.66±2.14)kg,and the biomass per plant of Salix matsudana was(16.68±1.36)kg.The biomass of herb layer in Populus×xiaozhuanica forest was(14.45±1.58)g.m-2,and the biomass of herb layer in Salix matsudana forest was(15.89±2.36)g.m-2.The carbon content of each organ of Populus×xiaozhuanica was 45%‒52%,and the one of Salix matsudana was 44%‒53%.The greenhouse gas emission reduction of 23.5 hm2 arbor forest in Saihan District in 2011 was about 999.99 t CO2 equivalent,including 602.01 t CO2 equivalent for Populus×xiaozhuanica forest and 397.98 t CO2 equivalent for Salix matsudana forest.
