林缘和土地利用/土地覆盖变化对中国东南部杉木林生物量碳动态的影响
发布时间:2021-09-23 04:46
将乐县国有林场位于中国福建省。将乐县总面积为2246.7 km2(东经117° 05’~117。40’,北纬26°26’~27°04’)。该地区为湿润的热带季风气候,并具有海洋和大陆性气候特征。平均相对湿度为81%,无霜期为287天。土壤湿润肥沃,类型为红壤土。全县年平均降水量为1699 mm,年平均气温为18.7°C。全县林地面积为1887 km2,占全县总面积的83.9%。林场的主要造林树种是杉木、毛竹和马尾松。其中,杉木是最主要的优势树种。(1)监测与绘制森林碳储量图对于评估减缓气候变化措施的效果至关重要。有证据表明林缘碳储量小于森林内部。本研究使用中国东南部地区杉木人工林生态系统的野外调查数据,对不同海拔高度处的杉木人工林林缘和森林内部的碳储量进行了测定和分析。研究结果表明,森林碳储量随海拔高度的增加呈现显著增加的趋势。研究结果也表明,林缘碳储量显著低于森林内部。杉木人工林碳密度值介于265 Mg C ha-1(林缘)和320 Mg C ha-1(森林内部)之间。本研究结果表明,忽略林缘效应的估计将高估碳密度达9.46%。综上所述,在国家碳储量调查的过程中应该充分地考虑林缘效应...
