A Dynamical System on How Plant Communities are Affected by Environment Factors and Population interactions

Abstract

The plant community has natural adaptability and resistance to the habitat environment. However, when the climate conditions of the habitat change, the growth status of the plant Community will also change. Intraspecific and interspecific competition also affect plant growth in the face of climate change. This paper will try to illustrate how plant communities are affected by environmental factors over time, where precipitation is the main element taken into consideration. First, build a model to analyze and predict the relationship between drought adaptation and the number of species in a plant community. Second, modeling the effects of mutual cooperation and competition between populations and incorporating effects on drought adaptation. Third, based on the model, predict the minimum number of species required for a plant community to benefit from local biodiversity. Finally, we discuss the effects of increased frequency and severity of drought on plant communities and make recommendations for the optimization of biodiversity.
