Embodiment Construction

[0021] Construction of a model system for assessing the impact of ozone on vegetation productivity (WRF-CMAQ-BEPS): The mesoscale meteorological model WRF can simulate and reproduce meteorological fields with high resolution on a regional scale, and has good simulation accuracy. Regional air quality The CMAQ model can analyze the concentration of atmospheric pollutants (including CO 2 Concentration) and nitrogen deposition, etc., can provide ecosystem models with atmospheric pollutants, CO 2 and nitrogen deposition data.

[0022] The BEPS model is a process-based, remote-sensing-driven mechanistic ecological model that can simulate the carbon, water, and energy cycles of ecosystems. The carbon cycle process mainly includes physiological and biochemical processes such as plant photosynthesis, respiration, carbon allocation, and soil respiration; the water cycle process includes physical and biological processes such as canopy interception, surface snow accumulation, canopy tra...

Abstract

The invention discloses a model system for assessing the influence of ozone on the productivity of vegetation in an area Including BEPS module, WRF module and CMAQ module. wherein the BEPS module comprises an ozone input module, a data transmission module and an influence module of ozone on photosynthesis and transpiration, and the ozone input module, the data transmission module and the influencemodule of ozone on photosynthesis and transpiration are additionally arranged in the model, so that the simulation precision of the system is improved.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a model system for evaluating the influence of ozone on vegetation productivity in a region. Background technique [0002] The productivity of terrestrial ecosystems is a key process of the carbon cycle, and the maintenance of its structure and functions is closely related to climatic conditions such as light, heat, and moisture. A large number of facts show that changes in atmospheric composition and air quality also have direct and indirect effects on the formation process of ecosystem productivity. Studies of different regions and different plant types have found that more than 90% of air pollution hazards are caused by ozone in the troposphere. Different research results show that ozone in terrestrial ecosystems can lead to 0-30% loss of food production and forest biomass, and the yield reduction rate of some crops can increase by 10 times in the next 20 years.
