【Abstract】 Data quality in the process of environment monitoring and evaluation is crucial for correct identification of environmental factors. By reference to the research results about data quality in environment management at abroad, a brief introduction is given to the concepts of data product and data quality, and some shortcomings in data quality for environment evaluation at present are pointed out. For improvement of data quality, it is suggested that the LCA (life cycle assessment) and TDQM (total data quality management) should be introduced into the identification of environmental factors.更多还原
