Three-dimensional visualization device and method for describing wetland vegetation eco-hydrology response

Abstract

The invention discloses a three-dimensional visualization device and a three-dimensional visualization method for describing a wetland vegetation eco-hydrology response. The device comprises a database, an input module, a texture editing module, an eco-hydrological model control module, a three-dimensional visualization module and a display module, wherein the database is connected with the inputmodule and receives and stores ground feature distribution data; the texture editing module and the eco-hydrological model control module are respectively connected with the database for receiving and storing the ground feature distribution data into the three-dimensional visualization computing module, and generating and outputting vegetation texture data; the eco-hydrological model control module receives an eco-hydrological model, and generates and outputs eco-hydrological model data; the database receives the vegetation texture data and the eco-hydrological model data, and establishes data information of the vegetation texture and the eco-hydrological model; the three-dimensional visualization computing module is connected with the database, receives the data information of the vegetation texture and the eco-hydrological model, performs grid computing, and generates and outputs a vegetation form, vegetation height and vegetation density of a coenosium of each grid node; and the display module is connected with the three-dimensional visualization computing module, and performs the three-dimensional visualization on the vegetation form, the vegetation height and the vegetation density of the coenosium.

Description

technical field

[0001] The invention belongs to the technical fields of water resource management, ecological environment protection and wetland restoration, and in particular relates to a three-dimensional visualization method for describing the ecological and hydrological response of wetland vegetation, in particular to decision support for wetland ecosystem management and popular science education on wetland ecology and hydrology based on visualization technology. Background technique

[0002] In recent years, the protection and restoration of wetlands has become an important way to improve the ecological environment, but in the specific implementation process, it is necessary to understand the ecological and hydrological responses of wetland vegetation. The traditional method analyzes the ecological hydrological response from the perspective of models and statistics, and predicts the physiological and ecological impact of the hydrological environment on wetland vegetation...
