Up to the present, there are 27 species of mosquitoes recorded in Peking. In 1953--1955, wehave collected 19 of them; among these, Culex pipiens var. pallens and Culex tritaeniorhynchus arethe commonest species in residental areas, where Aedes chemulpoensis, Aedes vexans, Aedesdorsalis, Amopheles hyrcanus var. sinensis and Anopheles pattoni are also frequently found. Culex pipiens var. pallans are usually found resting in dark places inside the houses, Culextritaeniorynchus, Anopeles hyrcannus var. sinensis, Anopheles pattoni, Aedes dorsslis and Aedesvexans are easily collected from the walls and ceilings of animal houses, whereas Aedes chemul-poensis prefers shaded places for resting in natural surroundings outside of houses. During winter,we also found that green houses, waste artificial caves of city wall, cellers in the field for sweetpotato storage, waste brick-kiln, basement of houses (without heat) are suitable places for hiberna-tion of Culex pipiels var. pallens. In both urban and suburban regions larvae of Culex pipiens var. pallens are prevalentfrom June to September, they were found in almost all types of water, but most of the breedingplaces of Culex tritaeniorynchus are found in the suburban regions. The seasonal distribution of mosquitoes is determined by periodical collection of adults inselecter stations, daily collection of adults in animal traping room and periodical collection of larvaeand pupae. During the 2 years periods, it was revealed that there are two peaks both in Culexpipiens var. pallens and Culex tritaeniorynchus, and the first peak usually occurred before 10thAugust. From the result of the study of ecology of mosquitoes as well as that of the seasonal and regionaldistribution of human cases we consider that Culex pipiens var. pallens and Culex tritaeniorynchusare the most important vectors of Japanese B encephalitis virus in this district.

1.于1953、1954年在北京市发现5属19种蚊子,在居民区内常见的蚊种有淡色库蚊、三带喙库蚊、骚扰伊蚊、仁川伊蚊、背点伊蚊、中华按蚊、帕氏按蚊。 2.淡色库蚊栖止在室内暗处,三带喙库蚊、中华按蚊、帕氏按蚊、骚扰伊蚊、背点伊蚊常栖止在畜舍内,仁川伊蚊多发现在室外阴凉处。 3.淡色库蚊成虫越冬场所为花洞子、废城墙洞、白薯窖、废砖窖、地下室、花窖等。 4.淡色库蚊、三带喙库蚊的消长曲线一年中出现两个峯,第一个峯出现在8月上旬以前;仁川伊蚊于8月上中旬出现一个峯。另外,在一年内以淡色库蚊活动的期限为最长,约7个月左右,三带喙库蚊、中华按蚊次之。 5.蚊子与当地脑炎流行的关系已予讨论,并推论淡色库蚊、三带喙库蚊可能为本市脑炎的主要传播媒介。

Based on the statistical analysis of families, genera and species and comparison of related regions, the flora of Peking has been preliminarily analized by present authors in following aspects. 1. The elements of Peking flora. (1) Statistical analysis of femilies, genera and species. a) According to the enumeration of "The Peking Flora" the vascular plants of Peking are belonging to 153 fatuities, 751 genera and 1025 species. b) Analysis of major families. Among Angiosperms 10 leading families are taken for accounting percentage of their number of species as follows: Compositae, 10% Gramineae, 9% Leguminosae, 6% Rosaceae, 6% Liliaceae, 4% Cyperaceae, 4% Umbelliferae, 3.8% Ranunculaceae, 3.6% Cruciferae, 2% Caryophyllaceae, 2% c) Statistics of ligneous plants. Woody plants exclusive of the cultivated ones there are 45 families, 96 genera and 199 species; that is about 29% to the total number of vascular plants. (2) The endemics: The endemics are not strictly restricted to the Peking area, they are also generally found in North China. Accooding to the records and specimens collected there are about 7 spp. which may be considered as endemics, such as Clematis acerifolia Maxim. in Paihuashan and Shangfangshan; Cnidium Smithii (Wolff) W. T. Wang in Paihuashan and Yangjaping) Ligusticum Wawrae Wolff in Chiehtai Sze of Mentougou. Besides, there are about 25 spp. which are distributed correspondingly to the mountain range of North China, as Xanthoceras sorbifolia Bge., a monotypie genera occurs almost over North China. (3) The comparison between flora of major regions in Peking: In order to define the floristie characters of different regions of Peking, the authors select Potou, Paihuashan, Kingshan, Shangfangshan, Tancheh Sze and Haitien as 6 major points to make some comparison. According to thedistribution of woody plants in different regions an index of similarity is obtained by calculation and comparison. From Table (1) it shows that the flora of hilly region is more similar to that of the plain (index number=0.75) , and that of Potou and Paihuashan is also closely related (0.77), but the fora of rugged mountainous regions and plain are quite different. Among the 6 regions, hence, there is difference not only between the abundance of spp., but also the composition concerned. (4) Comparison of Peking flora with adjacent regions. By means of the same procedure, the index of similarity shows that, firstly, the ligneous flora of Peking are more closely related to North-east China (0.7). Secondly, it also has intimate relation with the flora of Honan Province, but in the latter nu merous Mid-China elememts are interfused. Thirdly, there are some distinct differences between flora of Peking and Sonthern part of Kiangsu Province. Lastly, the Peking flora appears to have loose relation with flora of Shantung Province and its relation with loes plateau ia also concerned. As stated above, this material seems to have some value of reference as a criterion in dividing the North China flora into provinces and snb-provinces. (5) Monotypic genera: Among the 10 monotypic genera in Peking flora recorded by Bunge (1833) only 4 are recognized as really monotypic at present, they are Xanthoceras, Oresttrophe, Hernistepta, Anemarrhena. (6) The transitional characters of elements of Peking flora: Due to its geographical and geological situation Peking flora has its European-Sibiria elements and Northeast China dements as the southern border, and on the contrary, some elements of tropical origin meet their north bonder just within this area. 2. Origin of Peking flora and its division. By the analysis stated above, it shows that Peking flora is practically as a part of North China flora. In Peking flora there are numerous elements as the relics of Tertiary flora, meanwhile*some migrating elements from other regions are also present, especially in plain. Elements of tropical origin as components of Peking flora indicate that they were either as remnants of tropical climate during geological time or as migrants after glaciation. For the furfher division of Peking flora, extensive work should be done to give a real prospect. It is difficult to define those limitations at present. However, it is evident to note that flora of rugged mountainous region, low hilly rigion and plain are very different, flora of western part and eastern part of rugged mountainous region are also quite unlike; this seems as an useful reference for floristic division of Peking area.

一、北京的植物区系成分 1.科、属、种的统计和分析。 (1) 区系统计:根据“北京植物志”记载,北京共有维管束植物153科、75属、1025种。 (2) 主要科的分析;被子植物中10个主要科依次为: 菊科(Compositae),10%禾本科(Gramineae),9%豆科(Leguminosae),6%蔷薇科(Rosaceae),6%百合科(Liliaceae),4%莎草科(Cyperaceae),4%繖形科(Umbelliferae),3.8%毛茛科(Ranunculaceae),3.6%十字花科(Cruciferae),2%石竹科(Caryophyllaceae),2% (3) 木本植物统计:共有自生木本植物45科、96属、199种,豹占维管束植物的总数的19%,属的总数的13%弱。 2.特有植物:北京特有植物多与华北区系共有,根据标本与记载可以作为北京特有种的共7—9种,如槭叶铁线莲(Clematis acerifolia Maxim.)产于百花山、上方山,北京蛇床(cnidium Smithii(Wolff)W.T.Wang)特产于百花山、杨家坪,北京当归(Ligusticum Wawrae Wol...
