| 摘 要： | 为验证胡杨Populus euphratica春尺蠖Apocheima cinerarius Erschoff分布的河流廊道效应,以新疆巴楚县夏河林区胡杨林分布区作为研究区域,研究胡杨春尺蠖的传播规律,在前期采用多时相、中等分辨率的MODIS数据提取2001、2006、2011、2016年虫害发生区域的基础上,结合实地调查,对河流廊道效应进行验证。结果表明:近16年来胡杨春尺蠖的发生面积逐年增加,且增加趋势较为明显,无虫害区占比下降达59.48百分点;春尺蠖的空间分布体现出明显的河流廊道效应,距河流越远,虫害发生率越低,河流是其重要的传播途径;林业部门要注重对胡杨春尺蠖发生的重点区域进行精准防治,使春尺蠖发生的热点区域缩小。

| Abstract: | In order to verify the river corridor effect of the distribution of Apocheima cinerarius Erschoff on Populus euphratica, the distribution area of P. euphratica in Xiahe forest region of Bachu county, Xinjiang was used as the research area to study the occurrence of A.cinerarius. The multi-temporal and medium-resolution MODIS data were extracted for pest occurrence areas in 2001, 2006, 2011 and 2016, and combined with field investigations, the river corridor effect was verified. The results showed that the occurrence area of A.cinerarius on P.euphratica increased; the increasing trend was more obvious in the past 16 years, and the proportion of non-pest areas decreased by 59.48 percentage points. The spatial distribution of A.cinerarius reflected the obvious river corridor effect. The farther away from the river, the lower the incidence of pests, and the river was its main transmission route. The forestry department should pay attention to the key occurrence areas of A.cinerarius for precise prevention and control and reducing the hot spot of A. cinerarius. |
