Surface water environment ribbon category code
1 Scope of application
This standard specifies the categories and codes of surface water environment functional zones.
The water environment functional zone category code object in this standard is the rivers, lakes, canals, channels, reservoirs, etc. within the territory of the People’s Republic of China.
There are surface waters that use functions.
This standard applies to the management of surface water environment information collection, exchange, processing, use and environmental information system construction.
2 Normative references
The contents of this standard refer to the terms in the following documents. For undated references, the valid version applies to this standard.
GB 3838 Surface Water Environmental Quality Standard
GB/T 7027 Basic principles and methods of information classification and coding
HJ/T 416-2007 Environmental Information Terminology
HJ/T 417-2007 Environmental Information Classification and Code
3 Terms and definitions
The terms and definitions established in HJ/T 416-2007 and HJ/T 417-2007, as well as the following terms and definitions, apply to this standard.
Water environmental function zone
According to water use function, water environment pollution status, water environment tolerance (environment capacity), social and economic development needs, and pollution
The requirements for total emissions control, delineated water environment with specific functions.
4 Classification methods
4.1 Basic methods
The basic classification method of this standard follows the provisions and requirements of GB/T 7027.
4.2 Classification method of surface water environment functional area
The classification is based on the mixed classification method supplemented by the surface classification method and the line classification method.
The first-level category is divided into 9 categories according to the "Water Pollution Control Law of the People's Republic of China" and the requirements of GB 3838.
5 classification code
5.1 coding principle
5.1.1 Uniqueness
Each type of surface water environment ribbon category has only one code, and one code represents only one type of surface water environment ribbon category.
5.1.2 Rationality
The code structure is adapted to the classification system.
5.1.3 Extensibility
Have appropriate backup capacity to accommodate the ever-expanding needs.
5.1.4 Simplicity
The code structure is as concise as possible and the length is appropriate to save computer storage space and reduce the error rate of the code.
5.1.5 Stability
Once the surface water environmental function category code has been determined, it should remain unchanged as long as the name has not changed.
5.1.6 Normative
The type, structure, and format of the code should be uniform.
5.2 Coding method
Hierarchical coding is used, and each layer is digitally encoded.
The level of the surface water environment ribbon category code from left to right is from high to low, the left end of the code is the highest level code, and the right end is
The lowest level code. In a fixed incremental format, the sequential code uses an incremental digital code.
5.3 Code composition
The surface water environmental function category code is represented by two Arabic numerals, 01 to 99.
6 Surface water environment functional area categories and codes
The surface water environment function area category code is shown in Table 1.
