中文摘要	应用地统计学(GS)的原理与方法研究了外来入侵有害生物烟粉虱(Bemisia tabaci (Gennadius))为害新疆棉田的时空动态,并与经典统计学进行对比分析.两种方法一致表明,烟粉虱成虫在空间上呈聚集分布的格局,而各时期成虫的聚集程度依据空间变异随机程度所占的比例不同而不同.经频次分布检验,以零频率法参数拟合的负二项分布来表达其空间分布型最为合适.运用GS的分析方法,进一步得到种群分布面积变化与扩散的趋势,并依此对昆虫种群的扩散模型进行模拟.棉田烟粉虱成虫在田间7～8月份均存在一定的空间相关性,随机程度为19.22%～49.99%;空间相关距离(相关程)在一个月内从32m急速增至6372m,随后在2000～3000m的范围波动.从整个发生过程看出,烟粉虱从越冬场所顺风侵入大田后,迁飞扩散在很大程度上受风向的影响,属于典型的借助风力扩散的昆虫,其在棉田的垂直分布则与吐鲁番地区独特的暖温带大陆性干旱荒漠气候特征有关.顺风扩散时多从棉株上部叶片开始危害, 而逆风扩散时从棉株中、下部叶片危害.烟粉虱在棉株上建立稳定种群后,中、下部虫口密度要略高于上部, 这是烟粉虱对吐鲁番地区特殊气候的适应.
英文摘要	Using Geographic Information System (GIS) technology and geostatistics (GS) methods followed by simulation, we analyzed the spatial structure and distribution of Bemisia tabaci (Gennadius) in Xinjiang. We also conducted a parallel analysis using traditional statistics. Results from the two analyses revealed that the spatial distribution patterns of B. tabaci (Gennadius) on cotton were aggregated; that the aggregation degree fluctuated over time; and that the proportion of spatial variation had a random component. Using frequency distribution goodness of fit tests, the negative binomial distribution with its parameter set at zero frequency had the closest fit for predicting this species′ spatial distribution in Xinjiang. Results from the GS analysis of the variation in distribution areas and of adult diffusion patterns suggested that the adults of B. tabaci (Gennadius) were spatially correlated in cotton fields. The degree of randomness ranged from 19.22% to 49.99%; the distance range of spatial dependence varied from 32 min to 6372 min July and then fluctuated between a distance of 2000m and 3000m. B. tabaci (Gennadius) populations initially invade cotton fields downwind from their over-wintering areas. Thereafter, the distribution was largely affected by wind direction. It is a classic case of insect distribution caused by winds. Vertical distribution on cotton plants of B. tabaci (Gennadius) was influenced strongly by the effects of the warm temperate zone and of the continental arid desert climate in Turpan. The population initially damages the top leaves, and then proceeds to feed on leaves in the middle and bottom part of cotton plants in the field of downwind, whereas the damage will start with the middle and bottom part of cotton plants in the field of upwind. Once a population is established, its success is based on its adaptability of B. tabaci (Gennadius) to the characteristic climate of the Turpan region.
