整理研究了塔里木河流域胡杨林火灾与林火环境的关系,结果表明:天山冬半年的降雨量大小是影响火灾年周期变化的主导因素;火灾的季节性周期受植物生长周期和分布区相对湿度的影响;并论证了胡杨在极端干旱的生境条件下,对火这一生态因子表现为叶变异、韧皮部增厚、个体含水率高以及幼树的避火生长等适应性对策。 The relationship between the Populus euphratica forest fire and the forest fire environment in the Tarim River Basin was studied. The results showed that the rainfall in the Tianshan Mountains in the first half of the year was the dominant factor that affected the annual cycle of the fire. The seasonal fire period was affected by the plant growth cycle and the relative humidity The results showed that Populus euphratica under extreme drought habitat showed that the ecological factors such as leaf variation, phloem thickening, individual moisture content and the fire-fighting growth of young trees were adaptive measures.
