Shuitu Baochi Xuebao, 2022 为了科学评估中国退耕还林工程的固碳能力，收集整理了退耕还林一期工程（1999—2010年）详细的造林资料，结合中国主要树种的蓄积量（生物量）生长曲线和退耕还林前后土壤有机碳变化特征及各树种碳储量计算的相关参数，估算退耕还林工程1999—2050年的固碳量及其变化。结果表明：截至2010年，退耕还林工程造林总固碳量（土壤和植被）为355.87 Tg；工程实施期间，造林后期固碳量显著大于造林前期，平均每年固碳量为29.66 Tg；工程林固碳增汇潜力不断增加，预计到2050年中国退耕还林工程的固碳增汇潜力为1

Shuitu Baochi Xuebao, 2004 以恢复生态学为理论指导,区域可持续发展为目的,根据塔里木河中下游退耕还林还草的现状,建立退耕还林还草综合生态效益的评价指标体系和评价模型,应用层次分析法(AHP)原理推测塔里木河中下游生态林、经济林、牧草等3种退耕还林还草类型的综合生态效益指数,并与农田生态系统进行了对比研究。研究结果表明生态林、经济林、牧草等退耕还林还草类型的生态效益均大于农田生态系统。其生态效益指数排序为:经济林>生态林>牧草>农田。这一研究结果将为塔里木河中下游退耕还林还草工程规划、布局等经营方式提供理论依据。
