It is of great significance for environmental protection to explore the impact of climate and drought on different plant communities. We propose a grassland mechanism model based on ordinary differential equations to analyze the impact of different factors, including three modules and an assessment method for the environment. In order to quantitatively evaluate drought factors, we defined degree of drought as an indicator that plays an important role in the model. We implemented our model with MATLAB and made qualitative and quantitative analysis of analog data. As a conclusion, we propose five measures to give our contribution to long-term viability of a plant community and the larger environment.
