4.3 holistic
When setting up monitoring points, the natural environment, population distribution, land use, industrial layout, etc. of coastal areas should be considered
Socio-economic development situation, starting from the whole, reasonable layout, monitoring points between the coordination, fully reflect the main pollution on
The impact of the environment.
4.4 Stability
Once the monitoring points have been identified, they should not be changed in principle to ensure continuity and comparability of environmental monitoring data in coastal waters.

5.1.1 Monitoring points Place the area
Coastal sea environmental quality monitoring points are generally located in the waters of the sea, the Bohai Sea to consider the coast within 12 nautical miles;
Monitoring points can not reflect the scope of pollution, the location should be expanded, but not within the territorial waters.
5.1.2 Location method of environmental quality monitoring in coastal waters
5.1.2.1 Method for layout of environmental quality monitoring points in coastal waters
The shore monitoring site is generally located in the low tide line (or artificial shoreline offshore) to the sea direction 2 km to 8 km within the sea layout,
Silt shoreline in the past 3 years the average annual increase in the width of more than 10 times the distance from the layout, taking into account the important Gulf and estuary. When the shore
Sea town, densely populated area, important port, industrial park, important estuary and mariculture area, etc.
Monitoring point water quality in line with a class of seawater quality standards, should be in the vicinity of 0.5 km to 2 km to add a provision of a shore monitoring
Point, and on both sides of the natural coastline laying 1 to 2 shore control point. Coastal waters meet the quality of two types of sea water quality standard
Quasi-sea area, may be appropriate to reduce the number of monitoring points laid, for a class of sea water, can only set the shore monitoring points.

3000 km2 laying a trend point.
5.2 Coastal sea area environmental function area monitoring point layout
When the monitoring points are laid, each functional area shall be provided with a monitoring point on behalf of its environmental quality. Internal pollution
Source of the environmental function area, at least one station located in the sewage outfall on the outer boundary.
A. Area of less than 5 km2 functional area, with the adjacent functional area common distribution of a representative monitoring point, or use
The adjacent environmental quality monitoring points represent the environmental quality of the area.
B. An area of 5 km2 or more shall be provided with at least one monitoring point at the center; the larger area
Functional areas, should be based on the sea environment and natural characteristics, increase the deployment of monitoring points.
5.3 intertidal zone environmental quality monitoring point layout
In the area of natural shoreline select a representative intertidal zone, along the vertical direction of the coastline set at least one monitoring section. Participation
According to the local tidal type of tidal zone, in the climax zone with two points, the tidal zone with three points, low tide with cloth
1-2 points. The interdidal zone chosen to monitor should avoid the effects of human activities.
5.4 Determination and arrangement of monitoring points for pollution sources and pollution impacts in land area
