“…Usually, maintenance respiration is modeled as a function of total biomass (McCree, 1974) and less emphasis is placed on organ‐based respiration rates, largely because of a lack of detailed information on different rates. Some models, however, calculate respiration by roots to obtain CO 2 efflux rates to the atmosphere from the soil (Beegum et al., 2023; Bouma et al., 1997).…”

Agriculture is weather dependent, and changes in climate can have a drastic impact on our ability to feed, fuel, and clothe the world's population. Climate change is causing more frequent and unprecedented extreme weather events that are already negatively affecting agriculture. We need to assess the effects of extreme temperatures and rainfall on agriculture. Patterns of short‐term extreme weather events, such as elevated temperatures, flooding, and strong winds, are not predictable enough to design field experiments around. Process‐based crop and soil simulation models allow us to explore new management options and thus provide whole‐system‐based knowledge and management guides for different locations over variable climate conditions. By using crop simulation models, researchers can test different adaptation strategies and assess their effectiveness in reducing the impacts of climate change on agricultural production. In this paper, we discuss the development of crop models and how they have been used to assess the effects of a changing climate on agricultural productivity and propose methods for agriculture to adapt to those changes. We describe potential applications of crop models to assess regional issues such as irrigation demand, greenhouse gas emissions, and policy decisions. Better understanding of how weather and climate forecasts at various scales are provided and the reliability of these forecasts is important for using crop models as a planning tool. Different approaches for simulating long‐term climate change impacts on crop yield and seasonal yield forecasting are discussed. The use of ensemble models to better assess climate change impacts is also discussed.

“…Soil, plant, and atmosphere are regarded as dynamic physical systems in which energy transfer and material (water) transport occur all the time [31]. At present, this model has been widely used in agricultural research [32][33][34], but few studies have applied it to the effect of tunnel excavation on plants. The previous studies mostly ana-lyzed the effect of a tunnel excavation on local plants from the perspective of soil water matrix potential (SWMP) [35,36], but ignored other fluxes in the SPAC model, and did not further apply them to the study of ecological water level.…”

Keywordsgroundwater decline ecological water level SPAC model plant wiltDuring the excavation of tunnels in mountainous areas, groundwater may be lost, which affects the surface plants and ecology. In this article, taking Hengwu Tunnel in China as an example, based on the soil-plant-atmosphere continuum (SPAC) model, the relevant parameters were obtained by field test first, and then from the perspective of soil water matrix potential (SWMP) and soil water migration (SWM), the effect of groundwater level decline induced by mountain tunnel excavation on plant growth was studied, and the calculation method of ecological water level was put forward. The results show the following: (1) The wilting of plant roots is a dynamic process of gradual expansion from the middle of the root to both ends, and the response of SWMP in the root region to changes in atmosphere and groundwater level is lagging and non-uniform; (2) SWMP can be used to predict the degree of wilting of plant roots, while the final distribution and value of SWMP are only related to the position of the groundwater level, but not related to the decline rate of the groundwater level; (3) groundwater level and rainfall (P) will affect the value and proportion of each flux in the SPAC model, in which the relative transpiration ratio can be used to evaluate the growth of the plant and calculate the ecological water level of the plant.
