Sensitivity Analyses of the ELM Model,er models exhibit a few sensitivities, while net primary productivity and soil respiration are sensitive to a variety of parameters. In some cases particular parameters to which the model is sensitive are identified. The model shows several sensitivities expected on the basis of knowledge of the grassland ecosystem.作者: strdulate 時(shí)間: 2025-3-23 00:34
