Embodiment 2

[0059] In this embodiment, Handan is taken as an example to specifically describe the implementation process of the identification method.

[0060] 1. Data preprocessing

[0061] Acquisition and preprocessing of Huodian raw data; specifically, download the NPPActiveFire / Hotspot data of the target area from the NASA website, analyze the data, and cut it according to the Handan administrative area; the time range of the data is 2012.01.20- On December 31, 2018, the number of fire spots in Handan District during this time frame was 75,513;

[0062] Acquisition and preprocessing of "Ruby" heat source and heavy industry product data; specifically, download the heat source and heavy industry product data based on long-term fire point analysis from the Institute of Remote Sensing, Chinese Academy of Sciences, and regionalize the "Ruby" product data according to the Handan administrative region cut, among which the number of heat source heavy industries in Handan District is 81;

Abstract

The invention discloses a straw combustion fire point identification method based on heat source heavy industry region analysis. The method comprises the following steps: obtaining fire point originaldata, ruby heat source heavy industry region product data and ground surface coverage product data of a target research region; preprocessing the data respectively; constructing a heat source heavy industry buffer area space according to the preprocessed product data of the ruby heat source heavy industry area so as to identify a fire point type in the heat source heavy industry buffer area space; and identifying the straw combustion fire point according to the fire point type in the heat source heavy industry buffer area space in combination with the preprocessed surface coverage product data. The method has the following advantages: the characteristics of high time resolution, wide coverage range and heat source heavy industry area distribution and operation production of long-time-sequence active fire point data are utilized, the ground surface coverage product and the heat source heavy industry area are combined, the accuracy of straw combustion identification is improved, and misjudgment of high-frequency fire points of the heat source heavy industry on straw combustion fire points is avoided.

Description

technical field [0001] The invention relates to the technical field of straw burning fire point identification, in particular to a straw burning fire point identification method based on heat source heavy industry area analysis. Background technique [0002] Straw refers to the remaining part of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. my country is rich in straw resources, accounting for 20% to 30% of the world's total straw production, and its quantity is equivalent to more than 50 times the total grass production in northern my country. Burning straw seriously pollutes the environment and destroys the ecological balance. A large amount of smoke and dust produced by open burning threatens traffic safety and easily causes traffic accidents. Remote sensing data can be used to quickly monitor the situation of straw burning in a large area across the country. Using fire point data combined with surface cover product da...
