With the continuous progress of ecological civilization construction,the legislation in the field of ecological environmental protection in China has been increasing. However,it is a widespread phenomenon that dis-standardization in legislative language,such as the use of random words,tautology,and vague language exist in both national and local environmental protection legislation. This is not conducive to the maintenance of the unity and authority of the law,and to the correct understanding and application of the law. The phenomenon will also bring many obstacles to local legislation in the future. To standardize the use of legislative language in environmental protection,the relationship between the accuracy and vagueness of legislative language should be well dealt with,and a corpus of legislative language in environmental protection should be established. Furthermore,the talent pool system of specialists in legislative languages should be perfected and the review and error correction mechanism of legislative language should also be set up and improved.
