The invention provides an aquatic vegetation type determination method and device. The method comprises the following steps of: determining whether a to-be-detected underlying surface is a water body or not; when the to-be-detected underlying surface is a water body, determining whether aquatic vegetation exists in the water body or not based on a normalized vegetation index; when the aquatic vegetation exists in the water body, obtaining a backscattering coefficient of the aquatic vegetation through microwave remote sensing; and based on the normalized vegetation index and the backscattering coefficient, determining the type of the aquatic vegetation, enabling the aquatic vegetation comprise emergent aquatic plants, floating-leaved plants or diving plants. By adding the microwave remote sensing technology on the basis of optical remote sensing, not only can three-dimensional information of the aquatic vegetation be considered, the phenological and spectral characteristics of the aquatic vegetation can be considered, and the type of the aquatic vegetation can be accurately and efficiently identified and determined.
Description
technical field [0001] The invention relates to the technical field of vegetation determination, in particular to a method and device for determining the type of aquatic vegetation. Background technique [0002] Aquatic vegetation in rivers and lakes has always been the most concerned issue in academic circles and related management departments. Aquatic vegetation in rivers and lakes involves water environment, animals and plants in rivers and other aspects. At present, due to the continuous changes in the aquatic vegetation of rivers and lakes under the joint action of man-made and natural effects, relevant managers do not have enough access to relevant information, which creates greater uncertainty for the management of water ecosystems and the prediction of water environments. [0003] At present, my country mainly adopts the following methods to obtain aquatic vegetation types: one is to identify different vegetation types and their temporal and spatial distribution char...
