Pism-pik model is developed by Potsdam Institute of climate impact to simulate large scale ice sheet shelf system. It comes from the parallel ice sheet model (bueler and brown, 2009). PISM v1.0 is open source with high resolution. Since 2011, it has been widely used as a tool for scientific research.

Soil crop simulation model has become an effective tool to provide scientific basis for agricultural production and management decision-making. APSIM model was developed by Australian scientists to simulate various biological processes in agricultural system. In particular, the mechanism model of ecological and economic output of each component of the system under climate risk. APSIM has been verified and applied in soils with temperate continental climate, temperate marine climate, subtropical arid climate and Mediterranean climate zone, including clay, expansive soil, deformable soil, silty sandy soil, silty loam and silty clay loam, which can be used to simulate more than 20 crops such as wheat. APSIM model has good ability to describe crop structure and crop rotation sequence adjustment, crop yield, quality prediction and control, and soil water flow imbalance control under different planting patterns.

Glims model is jointly developed by University of Georgia and USDA-ARS, its predecessor is creams, which is mainly used for small-scale simulation. The water quality items that can be simulated include sediment, nitrate nitrogen, ammonia nitrogen, phosphorus nitrate, ammonia nitrogen, total nitrogen, total phosphorus, etc. The modified SCS curve number method was used to simulate rainfall runoff, and the priestly Taylor or penman Monteith method was used to simulate evaporation. By simulating the effects of ammoniation, nitrification, denitrification, volatilization, absorption and fixation, the nitrogen factor was simulated by combining empirical or semi empirical formula with the model. A long-term soil erosion model developed by Sharpley et al. Was used to simulate phosphorus. The pesticide composition was mainly aimed at the interaction of pesticide characteristics, soil texture, climate impact, management strategy, surface runoff leakage and adhesion. The model also simulated the pesticide transport in the rhizosphere.

DRAINMOD is a computer simulation model, which simulates the hydrological conditions of poorly drained high water level soil hourly with a long climate record (for example, 50 years). The model predicts the impacts of drainage and related water management practices on groundwater table, soil moisture status and crop yield. The parallel method is mainly used to analyze the hydrological conditions of some types of wetlands to determine whether the wetland hydrological standards meet the requirements of drainage or part of the drainage site. The model is also used to determine the hydropower capacity of the sewage treatment system. The model has been successfully tested and applied to various geographical and soil conditions. Over the past 20 years, the model's capacity has been extended to predict the impact of drainage and water resource management practices on hydrology and water quality in farmland and watershed wide agriculture and woodland.

Saysmosd is a computer program used to predict soil moisture, salinity of groundwater and drainage, depth of groundwater table, and drainage flow in irrigated farmland, using different hydrogeological and aquifer conditions to send different water management options, including groundwater for irrigation, and some crop rotation schedules, where spatial changes are explained by polygonal networks 。
