森林火灾风险管理从评估开始。这项评估使得多项研究工作的对象与许多火灾风险模型相关。我们感兴趣的模型是为地中海森林建立的。最后一个是根据三个因素的积分总和加权模型来设想的，其中每个因素都受到权重的影响，即其对火灾蔓延的影响的函数。然而，这种模式仍然很重要，值得发展和改进。为此，并看到了气候条件在火灾发生和蔓延过程中的重要性和影响，我们在本文中建议通过添加另一个气候因素（标记为ICL）来改进该公式，并将其以产品形式呈现，同时尊重相同的风险定义。应用所提出的模型，建议使用技术地理信息来绘制火灾风险程度。在此背景下，我们在阿尔及尔的 Bouzareah 丛森林中建立并应用了 SIG。独创性，因为它将允许人们了解火灾危险和环境的脆弱性，以便更好地控制风险。
The management of the forest fire risk starts with it assessment. This assessment made the object of several works of research and many models of fire risk have been related. The model that interests us here is that established for Mediterranean forests. This last is conceived according to a sum weighted model integral three factors, where each is affected by a weight, function of his influence on the propagation of the fire. However, this model remains critically and deserves a development and an improvement. For it, and seen the importance and the influence of climatic condition in the departure and in the propagation of fire, we propose, in this paper, to improve this formula by the addition of another climatic factor (marked ICL), and to present it under a product shape while respecting the same definition of the risk. The application of the proposed model, suggested uses the technical geomatics to mapping the degree of the fire risk. In this setting, a SIG has been established and applied on a forest of Bouzareah clump in Algiers. Originality as it will allow the understanding of fire hazard and vulnerability of the environment for a better control of risk.
