Abstract: 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.
