Problems solved by technology

The ground survey method is mainly carried out by selecting sample survey points and measuring the sample quadrats of typical river sections. Although the data obtained by this method has high accuracy for the survey points, the number of survey points is small and the representativeness of the points is not clear. , the disadvantage of high cost of manpower and material resources
The remote sensing survey method is mainly carried out by interpreting the land use type in the buffer zone on the remote sensing image. This method can monitor the ecological buffer zone of the river in an all-round way, and the cost of manpower and material resources is lower than that of the ground survey. Large, relatively inefficient problem

Embodiment 1

[0061] Embodiments of the present invention provide a method for remote sensing monitoring of river ecological buffer zones based on grid division technology, such as figure 1 As shown, the method includes:

[0062] S100: Obtain multi-spectral remote sensing image data covering river areas, land use classification data, and water system data of national basic geographic information data.

[0063] The multi-spectral remote sensing image data is preferably the remote sensing imaging data in the wet season of the river. The water system data of the land use classification data and the national basic geographic information data should be consistent with the time phase of the multi-spectral remote sensing image data. The time phase consistency refers to the time gap. As short as possible, it can be all the data in recent years.

[0064] The ratio of water system data in national basic geographic information data is 1:250,000, and the spatial resolution of multispectral remote sens...

Embodiment 2

[0102] An embodiment of the present invention provides a remote sensing monitoring device for a river ecological buffer zone based on grid division technology, such as image 3 As shown, the device includes:

[0103] The acquisition module 10 is used to acquire multi-spectral remote sensing image data covering river areas, land use classification data and water system data of national basic geographic information data.

[0104] The river waterline generation module 20 is used to generate two river waterlines on both sides of the river according to the multi-spectral remote sensing image data and the water system data of the national basic geographic information data.

[0105] The buffer outer boundary line generation module 30 is used to make a buffer zone with a certain width based on the water edges of the two rivers, and obtain two buffer outer boundary lines on both sides of the river.

[0106]The segmentation module 40 is configured to segment the outer border of the buf...

Abstract

The invention discloses a river ecological buffer zone remote sensing monitoring method and device based on a grid division technology, and belongs to the field of river monitoring, and the method comprises the steps: obtaining remote sensing image data, land utilization classification data and water system data; determining a river waterline according to the remote sensing image data and the water system data; outwards making a buffer area by taking the river water side line as a reference to obtain a buffer area outer side line; segmenting the outer side line of the buffer area in an equantmanner and dividing the river buffer area into a plurality of grid units; and judging the land utilization type of each grid unit according to the land utilization classification data, and determininga river ecological buffer zone distribution area. According to the invention, the current situation of the river ecological buffer zone can be rapidly monitored, and technical support is provided forriver ecological environment management.

Description

technical field [0001] The invention relates to the field of river monitoring, in particular to a remote sensing monitoring method and device for a river ecological buffer zone based on grid division technology. Background technique [0002] The ecological buffer zone is an important part of the river water ecosystem, which plays an important role in reducing land pollution entering the water body and improving the water environment capacity of rivers and lakes. Obtaining the current status and historical changes of the ecological buffer zone is crucial for the restoration of the river ecological buffer zone and other water ecological environments. Management decisions matter. [0003] Existing survey methods for river ecological buffer zone include ground survey and remote sensing survey. The ground survey method is mainly carried out by selecting sample survey points and measuring the sample quadrats of typical river sections. Although the data obtained by this method has...
