本文根据最优化理论原理,在综合考虑森林枯落物抑制土壤蒸发、控制土壤侵蚀及影响土壤矿质层温度三个主要的生态因子的前提下,提出了确定林地枯落物最佳蓄积量的方法。研究工作中,依此确定出华北落叶松人工林和辽东栎林地的枯落物最佳蓄积量分别为16.0吨/公颐和10.5吨/公顷。通过改变模型中的参数,本方法可用于任何立地环境中去。 Based on the principle of optimization theory, this paper puts forward the method of determining the optimal stock volume of forest litter based on three major ecological factors: forest litter inhibiting soil evaporation, controlling soil erosion and affecting soil mineral layer temperature. . In the research work, the optimal stock volume of litter in Larix principis-rupprechtii Mayr. And Quercus liaotungensis can be determined as 16.0 t / m and 10.5 t / ha, respectively. By changing the parameters in the model, the method can be used in any site environment.
