Embodiment Construction

[0069] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0070] Such as Figure 1-5 As shown, the embodiment of the present invention provides a kind of eco-geological map compiling method, and described method comprises the following steps:

[0071] S 1 : Based on regional remote sensing data, apply ENVI software for ecological remote sensing interpretation;

[0072] S 2 : Through the investigation of the regional plant environment, use the vegetation above-ground habitat index VAHI and the environment index LI to comprehensively characterize the ecological and geological conditions of the region, and reflect them in the corresponding maps to construct the vegetation above-ground habitat index VAHI and the environment index LI;

[0073] S 3 : Use the interpolation method in Arcgis 10.2 soft...

Abstract

The invention provides an ecological geological map compiling method, which comprises the following steps: S1, on the basis of regional remote sensing data, performing ecological remote sensing interpretation by applying ENVI software; s2, through regional plant territorial survey, representing the ecological geological condition of the region by using the vegetation above-ground habitat index and territorial index integration, reflecting the ecological geological condition to a corresponding map, and constructing the vegetation above-ground habitat index and territorial index; s3, carrying out interpolation on the data fields by using an interpolation method in Arcgis 10.2 software spatial analysis-interpolation, and carrying out reclassification on an interpolation result to obtain a classification result of the aboveground habitat index and the terrestrial habitat index; and S4, taking the regional geologic map as a base map, superposing the vegetation aboveground habitat index and the regional geologic index through an Arcgis 10.2 software space overlay analysis function, and drawing a regional ecological geologic map. According to the invention, the coupling of the above-ground habitat index and the territorial index of the plant is utilized, and the ecological geological condition of one region is represented from multiple dimensions.

Description

technical field [0001] The invention relates to the technical field of geological mapping, in particular to a method for compiling an ecological geological map. Background technique [0002] With the emergence of various ecological problems, the industry has deeply realized that the root of many ecological problems is geological problems, but the traditional single survey mode and mapping method cannot characterize the ecological environment and geological status of the region from multiple dimensions. [0003] At present, the ecological geological map compilation method reported in the prior art mainly adopts the multi-attribute overlay mapping method of natural complexes: the main process is: [0004] Investigate and map the regional characteristics and differentiation phenomena of geology, geomorphology, hydrogeology, environmental geology, etc. in the entire region, and use them as the basic layer for investigation and mapping; closely combine soil and vegetation, and fi...
