| 摘 要： | 利用GIS空间分析技术和知识发现技术研究了北京房山地区林木可燃性.通过将历史林火数据进行去噪处理、分类处理,建立房山林火数据库;用知识发现算法和GIS空间分析方法,研究不同林木的可燃性,并用传统方法获取了林分生物量.实验表明,林分的生物量与林木可燃性并无必然的联系,林分的燃烧是一种复杂现象,受到社会、经济等因素的影响.该结论对林火研究及林火应用管理具有一定的指导作用.

| Abstract: | The flammability of woods in Beijing area was analyzed using "3S"(GIS,RS and GPS) and knowledge discovery in database(KDD) technology.A forest fire database was established with the methods of denoising and classifying the forest fire data.The flammability of different woody species was studied with KDD and GIS spacial algorithm,and the forest stand biomass was obtained using the conventional method.The results show that forest stand biomass is not closely correlated with the flammability of woods.The inflammation of forest stand is influenced by social and economic factors.The results are expected to be helpful to the study of forest fire and the fire management. |
