天空地一体化秸秆焚烧监测平台建设

Construction of Space-Air-Ground Integration Crop Residue Burning Monitoring Platform

秸秆焚烧是大气污染的重要来源之一,因其发生具有随机性和分散性,难以快速、准确、全面地获得秸秆焚烧火点信息,监管部门监督执法面临较大困难。为提高秸秆焚烧的监测精度和效率,研发了高精度火点提取算法,基于多源卫星遥感数据对秸秆焚烧火点进行监测,制定了无人机、人工现场核实方案,对卫星监测的火点信息进行核实。开发了Web端和移动APP端系统平台,定向推送和展示火点信息。形成兼具发现和核查功能的天空地一体化秸秆焚烧监管体系。相关平台应用于2020年山东省春秋季秸秆焚烧火点监测,实现遥感监测火点58个,经核实后真火点为53个,准确率为91.38%。结果表明,该监管体系可快速提取高精度火点信息,为秸秆焚烧监管提供新的思路和手段。

Crop residue burning is one of the important sources of air pollution.Due to its randomness and disper⁃sion,it is hard to obtain the information of Crop Residue Burning Fire Points(CRBFPs)quickly,accurately and comprehensively,and regulatory authorities face great difficulties in supervision and law enforcement.In or⁃der to improve the monitoring accuracy and efficiency of straw burning,high-precision fire detection algorithms were developed in this study and used to monitor the CRBFPs based on multi-source satellite remote sensing data,and UAV and manual verification schemes were formulated to verify the CRBFPs’information.The sys⁃tem platforms of WEB and mobile APP were developed to directional push and display the fire points informa⁃tion.A space-air-ground integration supervision system for crop residue burning was established with the func⁃tions of detection and verification.Relevant platforms were applied to monitoring of the CRBFPs in Shandong Province in the spring and autumn of 2020,and 58 fire points,which include 53 true fire points after verifica⁃tion,monitored by remote sensing images,with an accuracy rate of 91.38%.The results show that the system can extract high-precision fire point information quickly and provide new ideas and methods for the supervision of crop residue burning.
