中国科学院成都生物所在氮添加下ECM菌丝分解对土壤有机碳积累和稳定性的影响中获新进展（图）
土壤 有机碳 循环 过程
2024/11/13
外生菌根（Ectomycorrhiza, ECM）是真菌和植物形成的一种独特而又高效的互惠共生体，菌根与其形成的外延菌丝（简称菌丝）共同主导了土壤复杂有机物合成、根源碳输入、土壤碳-养分循环等关键生态过程，是土壤碳固存的关键驱动者。然而，尽管ECM菌根在土壤碳循环过程中的重要作用已成为广泛共识，但现有研究大多将植物根系和菌丝的生态效应视为一个整体考虑，严重忽视了ECM菌丝分解和周转特征及其在调节土...
Faster cofactorization with ECM using mixed representations

1990年代以来中国教育生产力发展和经济增长的关系——基于ECM模型的实证研究
教育生产力 经济增长 ECM模型
2012/11/20
中国教育生产力水平的发展与经济增长之间存在着长期的稳定关系和短期的协调机制：从长期来看，中国的经济增长水平与教育生产力的发展之间存在稳定的协整关系。从短期来看，教育生产力的发展对经济增长的促进系数为0.77%，说明经济增长水平的提高不仅取决于前期教育生产力水平的提高，而且还取决于上一期教育生产力发展对均衡水平的偏离。从因果性分析来看，中国教育生产力水平的提高与经济持续增长是互为因果的关系，教育生产...
