摘要
笔者以桔小实蝇（Ｂａｃｔｒｏｃｅｒａｄｏｒｓａｌｉｓ）为研究对象，依据其生物生态学特性，选择了７项生态因子，以中国２９个有代表性的站点，１０年的气象资料（１９８６～１９９６），应用模糊综合评判的数学方法，探讨了该虫在中国的适生分布范围。结果表明，北纬２５°以南的地区为桔小实蝇的最适宜分布区，四川盆地和贵州的部分地区是桔小实蝇的适宜分布区，北纬２５°以北、长江以南的地区是次适生分布区，其余地区是非适宜分布区。
The Synthetic judgement on fuzzy mathematics involved twenty nine sites in China and seven climatic elements which affect the growth of Bactrocera dorsalis, using the data of last ten years (I.e 1986～1996) as the analytical materials. To make the effective judgement of various sites, the fuzzy mathematics analysis methods were used first. The results showed that the regions of south of 25N were most suitable for the pest, the Sichuan Basin and the partial region of Guizhou province were suitable areas, the region of between 25N and the Changjiang River was inferior suitable. The other regions of China were unsuitable.
