Illustrate as a example by the region of rank, but the invention is not restricted to be divided into 4 grades according to Water conservation size, can be according to water
Source self-restraint amount size is divided into the multiple grades such as 3 or 5；And be also not necessarily limited to extract the region of highest level, can be according to actual need
Ask, highest level region or highest level region and secondary high-level region or front 3 high-level region etc. are extracted, as water source
Conservation region.
The raster data in Characteristics and Water Conservation Function region is converted into vector format by step S24., is protected as Characteristics and Water Conservation Function
One ingredient of the delimitation of shield red line.
Step S3. is based on importance assessment result, by the Characteristics and Water Conservation Function region of vector format and at least one vector
The protection zone of change carries out space overlapping, obtains the preliminary defined area of Characteristics and Water Conservation Function protection red line.
By the Characteristics and Water Conservation Function region of the vector format obtained in previous step, with wetland park, Important Wetland, important water
The vector data of the protection zones such as source protection ground, important flood storage and detention basin, important rivers and lakes Water Functional Zone, important protection waters enters
Row space overlapping, obtains Characteristics and Water Conservation Function protection red line and tentatively delimit scheme.
The figure spot of the preliminary defined area that step S4. is obtained to previous step through space overlapping is modified, and obtains water source
Conservation protects the delimitation result of red line.
With remote sensing image and land use survey data as base map, carried out to being superimposed figure spot using GIS software
Polymerization is processed, and according to ecosystem integrity independent tiny figure spot and artificial land used are rationally deducted, and revision Characteristics and Water Conservation Function is protected
The preliminary defined area of shield red line.Specifically include following steps：
A. polymerization is processed
Using the cluster tool in GIS platform, such as in ArcGIS softwares under ArcToolbox
Aggregate Polygons functions in Cartography Tools modules, relative aggregation or neighbouring figure spot are polymerized to
Relatively complete figure spot in flakes.Setting polymerization distance is 250m in the present embodiment, and minimum hole size is 1km2.But, this
Bright to be not limited to above-mentioned polymerization distance and hole size, each administrative area can be appropriate according to the fragmentation degree of figure spot and area under one's jurisdiction area
Adjustment polymerization distance.
B. broken speckle is deducted
It is to avoid ecological protection red line plaque rupture, plaque area is independent thin below threshold value in the present embodiment
Little figure spot is deleted, and is deleted the area threshold of figure spot and can suitably be adjusted according to administrative area size, and the present embodiment is adopted
1km2As threshold value, it is not limited to 1km2。
C. artificial land used is rejected
According to the data such as present status of land utilization and planning, the large-scale construction land after polymerization in figure spot is deducted with concentration in flakes
Farmland.The present embodiment is based on land use survey data, deducts large-scale construction land and concentrates farmland in flakes.
D. border is optimized and revised
The Characteristics and Water Conservation Function obtained after above-mentioned process is protected into the vector data of red line, remote sensing image, knot is compareed
The physical geography border of the key elements such as mountain range, river, lake, the vegetation in conjunction remote sensing image, adjustment Characteristics and Water Conservation Function protection is red
The border of line, to keep ecosystem integrity and stability.
E. ground is verified
The result optimized and revised according to more than, further carries out ground and verifies, and finds out and be difficult on figure and clearly define or have
The red line block border trend of dispute, determines red line border flex point geographical coordinate.Result is verified according to ecological protection red line ground,
Ecological protection red line block border trend is corrected on vectogram, Characteristics and Water Conservation Function protection red line is formed and delimited scheme.
Process through the revision of above-mentioned a～e, be finally obtained the delimitation result that Characteristics and Water Conservation Function protects red line.

7. Characteristics and Water Conservation Function according to claim 1 protects the demarcation method of red line, it is characterised in that right in step S4
The figure spot of preliminary defined area is modified, including step：Polymerization processes, deducts broken speckle, reject artificial land used, optimize and adjust
Integral boundary and ground are verified.
8. Characteristics and Water Conservation Function according to claim 7 protects the demarcation method of red line, it is characterised in that
It is, using the cluster tool of GIS platform, relative aggregation or neighbouring figure spot to be polymerized to that the polymerization is processed
Figure spot in flakes；
It is that the tiny figure spot of independence by plaque area below threshold value is deleted that the deduction crushes speckle；
It is described to reject artificial land used and be the large-scale construction land that deducts after polymerization in figure spot and concentrate farmland in flakes；
The border of optimizing and revising is to combine the physical geography border in remote sensing image, adjusts Characteristics and Water Conservation Function protection red line
Border；
It is to find out be difficult on figure that clearly defining or have controversial red line block border moves towards, and determines red line side that the ground is verified
Boundary's flex point geographical coordinate, and correct ecological protection red line block border trend.
9. Characteristics and Water Conservation Function according to claim 8 protects the demarcation method of red line, it is characterised in that at the polymerization
Polymerization distance is 250m in reason, and minimum hole size is 1km2。
10. Characteristics and Water Conservation Function according to claim 8 protects the demarcation method of red line, it is characterised in that the deduction
