This paper presents the survey of 9 districts in North China with an object of understanding more about geographical distribution of air-borne pollens in relation with allergic diseases in the upper respiratory system. The findings prove to be a good guidance, beneficial both to the physicians who are treating the cases and to the patients who are receiving the treatments. The components of the peaks of the curves in Spring are nearly the same, they are usually formed of Ulmus (elm), Populus (poplar) and Selix (willow), with the exception that in the Spring curve of Lanzhou, Biota Orientalis dominates and at Huohot, Ulmus (elm) dominates. Like in the report on air-borne pollens in Peking, made by C. T. Chang as well as in our report on air-borne pollens survey in 9 districts in North China, Artemisia (sage) is found to be the chief component of the Summer-Autumn curve and the major offender in Summer-Autumn seasons in the etiology of upper respiratory allergic diseases. In contradistinction to Artemisia (sage), there are two exceptions such as in south China: In Shenghai, Ricinus (castor bean) and Humulus (Hops) are found to be the major offender instead of Artemisia (sage) and At Kwangzhou, Kwangdong province Wood Ephedra, Wild Amaranth (pigweed) are also found to be major offenders instead of Artemisia (sage). In addition to the major offender, Artemisia (sage) which was said to be dominant in Shenyang (Moukden) of Laoning province by Yuchin (cited from POLLINOSIS by Shih Ruei, Ragweed was first discovered at Shenyang (and Tehling, Fushuen and Dandong). A question is raised "How it came to China"? Preventive measures must be taken to eradicate it, otherwise it certainly will spread all over China.
本文介绍了对中国北方9个地区的调查，目的是更深入了解与上呼吸道过敏性疾病相关的气传花粉的地理分布。研究结果证明具有良好的指导作用，对治疗病例的医生和接受治疗的患者都有益。春季曲线峰值的组成成分几乎相同，通常由榆属（榆树）、杨属（杨树）和柳属（柳树）组成，不过兰州春季曲线中侧柏占主导，呼和浩特则是榆属（榆树）占主导。与常崇涛关于北京气传花粉的报告以及我们关于中国北方9个地区气传花粉调查的报告一样，蒿属（艾草）被发现是夏秋曲线的主要成分，也是夏秋季节上呼吸道过敏性疾病病因中的主要致病因素。与蒿属（艾草）不同的是，中国南方有两个例外情况：在上海，蓖麻属（蓖麻）和葎草属（啤酒花）被发现是主要致病因素而非蒿属（艾草）；在广东省广州，麻黄属（木贼麻黄）和苋属（野生苋）也被发现是主要致病因素而非蒿属（艾草）。除了被认为是主要致病因素的蒿属（艾草）外，据于钦（引自石瑞的《花粉症》）称，豚草属（豚草）在辽宁省沈阳（奉天）占主导地位，豚草最早在沈阳（以及铁岭、抚顺和丹东）被发现。有人提出一个问题：“它是如何传入中国的？”必须采取预防措施根除它，否则它肯定会在中国各地蔓延。
