摘要
以2001—2003年频振式杀虫灯诱杀成虫数据为基础,采用地统计学方法,以地理信息系统的ArcGis为平台,分析并显示出:新疆和田地区春尺蠖种群成聚集分布,聚集半径在154.29￣243.76km之间,聚集中心由2001、2002年的皮山县、洛浦县两个聚集中心扩展到2003年的皮山县、洛浦县、民丰县三个聚集中心,各年的聚集程度有所变化,种群数量成递增趋势。
Based on the light trap number of Apocheima Cinerarius Erschoff male imago in 2001, 2002 and 2003 in Hetian Xinjiang, The geostatistics and geographic information system methods were used to analysis the dynamics of Apocheima Cinerarius Erschof population spatial pattern, the results are follow： The Apocheima Cinerarius Erschoff population spatial pattern is aggregated distribution in Hetian Xinjiang, The semidiameter of aggregation is from 154.29 km to 243.76 km, The centers of Apocheima Cinerarius Erschoff population aggregation from two of Pishan County and Luopu County in 2001 and 2002 extended to three of Pishan County , Luopu County and Minfeng County in 2003. The level of aggregation is dynamic each year and the population amount trend is increased by years.
