摘　　要：基于GIS技术,利用1951—2010年中国南方地区289个气象站点观测资料和褐飞虱历史越冬考察资料,通过采用典型年褐飞虱越冬实况调查资料进行检验,对前人研究的褐飞虱越冬北界指标进行优选,最终选择1月10℃等温线作为中国褐飞虱越冬北界位置确定的指标,分析了最近60年来气候变暖背景下中国褐飞虱越冬北界年代际变化以及前后30年的变化。结果表明:在气候变暖背景下,由于暖冬年份频次的增加,使得每隔10年、30年褐飞虱越冬北界平均界限均不同程度北移,与冷冬年相比,暖冬年褐飞虱越冬北界位置可向北推移2～3个纬度;年代际变化以20世纪80年代最为明显,80年代之后的30年较之前的30年北移显著;空间北移较明显的地区为云南中部和福建南部,其中云南境内最大位移处60年约向北移动了近90km。Based on GIS technology, and by using the meteorological data from 289 meteorological stations as well as the historical overwintering data of brown planthopper （BPH） in southern China in 1951-2010, this paper chose the January isotherm of 10 ℃ as the optimal index to identify the northern distribution boundary of BPH overwintering in China. The optimal index was selected from the indices in previous researches by the verification of the actual overwintering data of BPH in typical years, and then, the inter-decadal variation and inter-30-year variation of the northern distribution boundary in the past 60 years were analyzed. The results show that under the background of climate warming, due to the increase of the frequency of warm winter years, the average northern distribution boundary of BPH overwintering in southern China moved northward. Compared with that in cool winter years, the northern boundary in warm winter years moved northward by about 2-3 degrees in latitude. The average distribution boundary in the 1980s moved northward most obviously in decades, and that in 1981-2010 moved northward significantly, as compared with that in 1951-1980. The significant north-moving occurred in the central part of Yunnan Province and the southern part of Fujian Province, and the maximum distance of the north-moving in Yunnan Province in the past 60 years was about 90 km.
