Embodiment 1

[0039] Example 1. Establishment and application of forest fire warning system in Nanjing, Jiangsu Province

[0040] Based on FWI, the present invention develops a forest fire risk index early warning system that is more suitable for the specific situation of our country, and the implementation case takes Nanjing as an example.

[0041] By the end of 2011, Jiangsu Province had 2,174,500 hectares of forest covered area, 1,815,300 hectares of forest land, a forest coverage rate of 21.2%, and a total stock of 87 million cubic meters of living trees. Among them, the forest area in southern Jiangsu is 459,300 hectares, the forest coverage rate is 23.3%, and the total volume of living trees is 14 million cubic meters; the forest area in central Jiangsu is 269,600 hectares, the forest coverage rate is 19.3%, and the total volume of living trees is 7.7 million cubic meters; The forest area in northern Jiangsu is 1.0864 million hectares, the forest coverage rate is 26.7%, and the total ...

Abstract

The invention relates to an FWI early warning system and the specific application of the FWI early warning system in the forest fire early warning. The humidity, the illumination time, the wind speed and other parameters of natural conditions at specified areas are measured in real time, the hazard level of the forest fire is forecast, and the effect of quantizing various FWIs is achieved.

Description

technical field [0001] The invention relates to a forest fire weather index (FWI index) early warning system and its specific application. Background technique [0002] Although forest fires have always been accompanied by the migration of human historical habitats, forest fires are not ordinary natural disasters, but natural disasters that seriously damage the ecological environment, threatening the safety of human life and property. Forest fires not only destroy forest resources, but also seriously damage the ecological environment. Forest fires are sudden and destructive, and have become the biggest threat to global ecological security in the 21st century. At present, there are more than 200,000 forest fires in the world every year, burning 6.4 million hectares of forests, accounting for 1.8‰ of the total forest area in the world. my country is one of the countries with the most serious forest fires. Due to natural and historical reasons, forest fires occur frequently, ...
