Abstract: Photosynthesis is a crucial process that drives the biogeochemical cycle and energy flow in an ecosystem. Plants can be divided into three types according to the photosynthetic types, which are C3 plants (most species such as wheat), C4 plants (corn, dominant species in tropical and subtropical grasslands) and CAM plants (cacti, arid areas) dominant species). These three types of plants have different physiological response and adaptation mechanisms to climatic factors such as high temperature, drought, and CO2 concentration: they originated from different historical periods; the photosynthetic system evolves in a coordinated way with physiological mechanisms such as water transport and nitrogen resource allocation; finally, they coexist in the vegetation of the current ecosystem. My research explores the "origin-coordinated response-coexistence" evolution process of vegetation photosynthesis, reveals the mechanisms of physiological processes such as photosynthesis, water transport, and nitrogen utilization, thereby clarifying the coupling mechanism of ecosystem carbon-nitrogen-water cycles.
