摘要:

农林复合系统由于林分、农作物和土壤之间的相互作用而对储藏和固定碳具有巨大的潜力。其已经成为减少大气CO2浓度、解决全球气候变暖问题的重要土地利用方式之一,将会对陆地生物圈中通量的输入和碳的长期贮藏产生重要的影响。对豫东平原农区5,9,11和13年4个不同林龄的杨农间作复合系统的生物量、生产力和碳截存量进行测定和研究,结果表明: 豫东平原农区5,9,11和13年4个不同年龄段的杨农间作复合系统的总生物量分别为33.03,103.06,124.30和154.60 t·hm-2。4个年龄的杨农间作复合系统平均净生产力分别为19.95,29.30,33.24和56.94 t·hm-2a-1。豫东平原农区5,9,11和13年4个年龄的杨农间作复合系统总碳截存量分别达到了19.86,52.42,62.45和76.44 t·hm-2

Abstract:

Biomass Production and Carbon Sequestration in Poplar-Crop Agroforestry Ecosystems in Eastern Henan Plain Abstract:Agroforestry systems have a great potential for storing and sequestering carbon because of the close interaction between crops, trees and soil. It has been suggested that agroforestry system is one of efficient manners to use land in reducing CO2 concentration and alleviating CO2-induced global warming. It will have a great impact on flux and long-term storage of C in the terrestrial biosphere. The present experiment investigated the biomass productivity and carbon sequestration in poplar-crop agroforestry ecosystems at different forest ages of 5, 9, 11 and 13 years old in the eastern Henan plain. The results showed that: the biomass of poplar-crop intercrop agroforestry ecosystems at different ages of 5, 9, 11 and 13 years old was 33.03, 103.06, 124.30 and 154.60 t·hm-2, respectively; the average net-production was 19.95, 29.30, 33.2 and 56.94 t·hm-2a-1, respectively. The total carbon sequestration was 19.86, 52.42, 62.45 and 76.44 t·hm-2.
