Abstract: Chronic obstructive pulmonary disease（COPD）is now the third leading cause of death in the world，after ischemic heart disease and stroke.However，clinical practices in China still have many challenges to address COPD as an important public health issue，such as insufficient patient education，missing follow-up data，non-standardized management of stable COPD and/or acute exacerbations，which may be important causes of frequent aggravation and deterioration of conditions，leading to increased difficulties in treating and higher possibility of poor outcome after late treatment as well as increased social and economic burden of COPD.Therefore，it is of great practical significance to accelerate the standardization of prevention，diagnosis and management of COPD to improve the accuracy and effectiveness of diagnosis and treatment of COPD.To provide a reference for emergency and respiratory clinicians to better treat COPD patients clinically，in view of domestic diagnosis，treatment and studies regarding COPD，we comprehensively interpreted the 2020 GOLD's Global Strategy for Prevention，Diagnosis and Management of COPD in three parts from a clinical perspective： pharmacological and non-pharmacological treatment of stable COPD and management of exacerbations.This paper is the first part of interpretation，mainly including diagnostic evaluation，initial management and follow-up management.
