Can century model simulate soil respiration? Practice technology application and case analysis of century model

CENTURY Model , Biogeochemical cycle model of terrestrial ecosystem mainly based on process . It is mainly used to simulate different soils

- Between vegetation systems C、N、P and S Long term dynamics . According to the decomposition rate of soil organic matter ,CENTURY The model takes the total organic matter of soil

carbon （TOC） It is divided into three carbon pools , Namely activity 、 Chronic and inert organic carbon pool .

Through a complete case study , Add Deep understanding and application in practical projects . because “ Carbon neutralization ” high-profile , Case selection , Focus on the content of carbon , It is more in line with the needs of research hotspots

CENTURY Model is introduced And installation

The construction of relational model and Should be use     CENTURY Model principle       CENTURY Structure of model       Model installation And notes

  Introduce the characteristics of relational model 、 advantage 、 The build process 、 And precautions for application ;

 CENTURY Development and principle of model ;
