Embodiment Construction

[0021] The present invention will be described in further detail below in combination with specific embodiments.

[0022] A method for estimating community diversity based on remote sensing data heterogeneity, the method comprising the following steps:

[0023] 1, obtain LandsatTM remote sensing image data, carry out radiation correction as shown in formula ③;

[0024] E=EOA, formula③

[0025] Among them, E is the electromagnetic wave energy received by the sensor, EO is the radiation energy of the surface object, and A is the attenuation coefficient of the atmosphere, which can be obtained from the atmospheric parameter device on the remote sensing platform;

[0026] Correct the geometric distortion of remote sensing images caused by other factors by using ground control points GCP (points that are easy to identify and can be accurately located on remote sensing images);

[0027] The gray value ratio of any two bands corresponding to pixels in the same area obtained simulta...

Abstract

The invention discloses a community diversity estimation method based on the heterogeneity of remote sensing data. The method includes: obtaining remote sensing data, performing radiation correction, geometric correction and terrain correction, and extracting 450, 470, 800, 465, 681, 750 , The vegetation reflectance at 550nm is used as the spectral data; the acquired spectral data is corrected and checked to ensure that there is no data error; the acquired spectral data is smoothed; the variance SD between the reflectances of each band between 450-470nm is calculated ; Calculate the plant species diversity index Y. The present invention can quickly estimate the diversity of plant species, and can be widely used in the rapid assessment of the richness of plant species in grasslands, grasslands, shrubs, farmland, and nurseries; the diversity index of plant species can be quickly determined without a lot of manpower and material resources It has the advantages of efficient information processing and saving input costs.

Description

technical field [0001] The invention relates to a method for estimating community diversity, in particular to a method for estimating community diversity based on the heterogeneity of remote sensing data. Background technique [0002] Community heterogeneity is one of the important indicators of ecosystem stability. It is widely used to indicate ecological resilience and sustainability, and is used for ecological quality evaluation, ecological construction and ecological governance. Remote sensing technology has been widely used in ecological environment monitoring, crop pests and diseases, crop yield estimation, geological and mineral exploration, etc., and is playing an increasingly important role. The spectral characteristics of plants are the changes in light absorption, transmission and reflection caused by physiological and ecological characteristics and compositional structure characteristics. Remote sensing data can be used to quantitatively invert vegetation physiol...
