The invention discloses a three-dimensional visualization device for watershed vegetation hydrological response

Abstract

The invention provides a three-dimensional visualization device for watershed vegetation hydrological response, and belongs to the field of vegetation hydrological monitoring, and the device comprisesa data collection module which is used for collecting water area vegetation hydrological data, and carrying out the preliminary processing of the data, and obtaining primary data; The data processingmodule is used for performing de-noising processing on the primary data to obtain secondary data; The three-dimensional data conversion module carries out classification processing on the data; The three-dimensional visual calculation model receives the binary data sent by the three-dimensional data conversion module, performs grid calculation on the data to form grid nodes, and generates and outputs vegetation characteristics and hydrological characteristics of each grid node; And the display module carries out three-dimensional visual display on the vegetation according to the vegetation characteristics and the hydrological characteristics output by the three-dimensional visual calculation module. According to the device, the acquired watershed vegetation hydrological data are processedand converted, so that the three-dimensional visual display of watershed vegetation ecological hydrological response is realized, and people can understand the relevant information of watershed vegetation hydrology more intuitively.

Description

technical field [0001] The invention belongs to the field of vegetation hydrological monitoring, and in particular relates to a three-dimensional visualization device for hydrological response of watershed vegetation. Background technique [0002] With the development of society, the degree of damage to the environment by human activities is becoming more and more serious. In order to protect the environment that people can survive, people have paid more and more attention to the research on the water temperature response of watershed vegetation in recent years. [0003] Changes in vegetation are reflected in the coverage of surface vegetation. Changes in vegetation coverage will inevitably have a huge impact on the hydrological state of the watershed, especially the catchment process of precipitation in the watershed and the output of runoff. Water is the carrier of soil erosion. Therefore, the vegetation status largely determines the erosion intensity of the soil. Therefo...
