摘要
本文利用杀虫灯诱杀春尺蠖雄成虫的数据,采用地统计学空间插值方法,借助遥感(RS)和地理信息系统(GIS)技术,得出2001~2003年和田地区春尺蠖种群空间分布格局及其动态。结果显示,3年中春尺蠖种群均为聚集分布,但聚集程度、种群空间分布和数量处于动态变化之中。通过TM卫片解译提取和田地区森林图层,在ARCGIS中完成对插值模拟图的切割,从而把春尺蠖种群动态的年际分布显示在具体的森林斑块内。研究结果可作为进一步研究春尺蠖种群暴发机理和系统控制的基础。
The geostatistics method combined with RS and GIS technique was used to study the spatial distribution pattern and dynamics of Apocheima cinerarius (Erschoff) populations in 2001 - 2003 based on the data of A. cinerarius adults collected in light traps in Hetian, Xinjiang in these three years. The results showed that the A. cinerarius populations were in aggregated pattern of distribution during the three years in this district, but the aggregation degree as well as the spatial and quantitative distribution varied dynamically. Through interpreting the TM images and extracting the forest coverage of Hetian district, the cutting of simulation maps was completed with the help of ARCGIS software, and the A. cinerarius population distribution in concrete forest patchs was thus displayed. These results may serve as the basis for further studying the outbreak mechanism and integrated control strategies of A. cinerarius populations in Xinjiang.
