Fire Risk Monitoring of Tamarix chinensis Forest Based on Infrared Remote Sensing Technology

Abstract

In this study, the Tamarix chinensis forest in Changyi national marine ecological special protected area in Shandong province, China, was researched for forest fire monitoring based on thermal infrared remote sensing technology. We summarized the commonly monitoring methods for forest fire point based on remote sensing technology into two types: fixed threshold method (including its deformation model and extension model) and adjacent pixel analysis method (also known as background pixel correlation method). And we analyzed the advantages and disadvantages of these two methods. The BT (brightness temperature) data inverted from the remote sensing images of IRS sensor (HJ 1B satellite) and TIRS sensor (Landsat-8 satellite) indicated that there not had enough thermal radiation to form a fire point during the above phases in the protected zone. The research results and methods also confirmed that thermal infrared remote sensing technology can be used for forest fire monitoring and identification of macro forest fire point.
