The so-called "landscape horizon" in this paper is viewed from the fact that the landscape acts as an objective and independent substance of matters on the surface of the earth Along a given line in any unit of regions the landscape may be sectioned crossly Landscape is a component part on the land of the landscape sphere, which envelopes the earth, so that its basic components are also .solid, gas, liquid, and organic matters. The science of the landscape may be therefore considered as regional geography. All the evidences concerning the completion of major types of the landscape, the floral and faunal extinction and new species—production, and especially the apperance of man prove thai the history of the landscape can only date back to the begining of the Quaternary Era, so that palaeogeography may be restricted in this scope. According to time, the landscape includes naturally the weathering crust as its bass, and its upper end should be coincided with the top of air near the ground, or of the highest trees. Thus its thickness is all the same in standard to any reginal unit Obviously, the extent of the landscape do not exceed the continental slopes in the sea. Judging from the statements mentioned above, a horizon of four dimensions has to logically occur in any unit of regions. It is the "landscape horizon", in which vertical and horizontal differentiations have continuously proceeded. Controlled by some geographic processes, the "landscape horizon" has been vertically differentiated into three sub—horizons: the sub—horizon of weathering crust, of soils, and of biotic community and air, They altogether revealed the morphological structure in types of the landscape. The horizontal differentiations conditioned by some other gcogra phic processes indicate the relationships of the landscape in areal continuity. The diagrams of the "landscape horizon" must be based on field works. Here are two examples, one, for the "landscape horizon" of steppe, and the other, of desert (figures 1 and 2). These diagrams can be used to (1) point out the structural and ecological features, in other words, the typological characteristics of the landscape, (2) determine the boundaries of regions and provide a basis for the plan of agriculture, and (3) help to study some theoritical problems of regional divisions. The author believes that the concept of the "landscape horizon" may be nseful in practical as well as in theoritical works.

本文所谓“景观层”是出之于景观是地球表面上起作用的一种客观的独立的物质实体的看法。在区域任一单元的一定线上景观能用剖面体现出来。景观是环围地球的景观壳在陆地上的一个组成部分,因之它的基本组成要素也是固体,气体、液体、和有机质。以此之故景观学可以认为是区域地理学。所有景观主要类型之完成,动植物之死亡和新种之产生,和特別是人类之出现的证据都证明景观历史仅能回溯至第四纪之始。古地理学因此应当限于这个范畴之內。根据时间,景观的下限自然包有风化壳,而其上限则与近地面空气层或最高乔木顶部相一致。显然,它的广度不超过大陆斜坡。由上可知一种具有四度空间的层必见于任何区域单元之內。这就是“景观层”。其中垂直和水平分异作用不断进行着。为一些地理过程所规定,“景观层”在垂直方向上被分异为风化壳,土壤、和生物与空气三个亚层。它们共同揭示了景观类型的形态构造。而受制于另一些地理过程的水平分异则表明景观在空间连续性上的相互关系。“景观层”图解根据野外工作制出。这里举出二例:一为草原“景观层”图解,另一则属于荒漠(图1和2)。这种图解可用以(1)指出景观的构造和生态特征,换言之,郎其类型特点;(2)确定区域的界限并为农业规划提供基础,和(...

China is one of the countries with the most numerous species of Dendrolimus in theworld. There are 13 known species. According to the research on the classification anddistribution of Dendrolimus in the country, by the Institute of Zoology, Academia Sinica,during the past years, the results indicate distinctly that their geographic distribution andthe distribution of their host-plant are closely related. Selecting the highest grade flora of China, we draw a line which divides the wholecountry into two main portions: the eastern and western divisions. The former, wherethe climate is humid and pine forests are luxuriant, is the main distributional region ofDendrolimus, while the latter, where weather is arid and with plenty of desert stepp-es, generally there are no Dendrolimus. At the same time, it has also been discoveredthat the distribution of Dendrolimus is not only closely related to altitude, but also tolatitude. According to the distribution of their host-plant, Larix olgensis var. koreanaand Pinus massoniana (with the isotherm of an average temperature of January at--12℃ and 0℃), we assume to subdivide the eastern division to 3 regions as north-eastern, northern and southern districts of China. In each of the districts there are dif-ferent distributions of Dendrolimus. Generally in the northeastern district of China, theD. sibiricus Tschetv. is distributed. The northern and the southern districts of China mayagain be subdivided into its own inland and coastal parts. The D. tabulaeformis Tsaiet Liu is distributed in the terrestrial and the D. spectabilis Butler in the coastal partof northern district of China. A great part of southern district of China is distributedwith coastal D. punctatus Walker, and the southwestern inland region is distributed withthe D. latipennis Walker, D. xichangensis Tsai et Liu and D. kikuchii Mats. The divisionbetween inland and coastal parts within the two districts mainly depends upon the dis-tribution of the host-plant of Pinus tabulaeformis Carr. and Pinus massoniana Lamb.

我国的松毛虫种类已知的有13种,是世界上已记载的松毛虫种类最多的国家。 根据中国科学院动物研究所历年来在国内所收集的松毛虫种类和分布的资料,结合已知主要松树种类的天然分布进行综合分析的结果,显示出松毛虫不同种类的地理分布与其寄主植物的天然分布有着密切的相关。例如西伯利亚松毛虫的分布只限制在东北地区兴安落叶松、黄花松的天然分布范围里,油松毛虫在油松分布区,赤松毛虫在赤松分布区,云南极毛虫在云南极分布区以及马尾松毛虫在马尾松分布区等。 由于这些松树种类彼此间的天然分布界限十分明显而基本上少有重迭,因此试将我国东部地区松毛虫不同种类的地理分布按照其寄主植物划分为以下三个部分、五个松毛虫区: 一、东北部分 北界大兴安岭,南至安东—沈阳线(相当于全国一月份平均-12℃等温线),是西伯利亚松毛虫主要分布区,也是兴安落叶松和黄花松天然分布所在地。故名1)西伯利亚松毛虫区。 二、华北部分 北界西伯利亚松毛虫区,南至淮河流域(相当于全国一月份平均0℃等温线),是油松毛虫和赤松毛虫主要分布区,也是油松和赤松的主要分布所在。因此可分为2区: 2)油松毛虫区 主要位置在冀热山地和黄土高原东部,是油松毛虫分布区,是油松分布所在地。 3...

This paper has been prepared as a supplement and rectification to "PreliminaryObservations on Faunal Regions of Termites in Southern Part of China" published by thesame authors in 1957. In the first part of this paper, based on the conceptions of "Quality, Quantity,Time, and Space" to study the subject, an attempt has been made to define tentative-ly the terminology" the Fauna of the Insect". The term is used here to designate the specific forms and number of the insect or-ganism in a certain space at a moment. Classifying insects into different Faunal regionsis to give expression to the forms and number within a certain taxonomic unit of variousdimensions by systematic grading, thus showing the identity and particularity of eachother and possibly interpreting the law of their development in course of time. The Faunal Region of Isoptera has been tentatively divided into five grades: 0. Supplemental grade--Kingdom 1. World grade--Region and Sub-region 2. Termo grade--Zone and Sub-Zone 3. Eco-pattern grade--Eco--fauna and sub-ecofauna 4. Domicile grade--Habitat In the second part of the paper, a modified scheme for classifying the Faunal regionsof Isoptera in China is presented. The Isoptera in the above-mentioned district has been classified on the degree ofeco-fauna for the time being with taxomical genera as its basis. And a brief accountof the geographic locations of different eco-faunae, their composition and economic im-portance has been given. The following figure is presented to outline the Faunal regions of Isoptera in China. Finally, the geographic origin of Rhinotermitidae, the distribution characteristics ofMacrotermitinae and the relationships between Isoptera in China and those of other sub-regions of Oriental region are discussed. The newly-proposed central-China sub-region is the one besides the four existing sub-regions, the boundary in the eastern part of China between Palaearctic and Orientalregions is determined to be some where about 35°North latitude.

本文首先以质、量、时、空的概念,为区系加以定义。就等翅目进行了区系的系统等级划分。简述了各区系间的地理位置、种属组成、生态特性和其经济意义。从不同分布地区存在着的物种形式与组成和数量的差异,分析它们和社会主义建设的关系。最后讨论了犀螱科的地理来源,大螱亚科在我国分布的特色及我国南方等翅目区系与其他东洋热带地区等翅目区系的亲缘关系。至于作者等新拟的华中亚区,是东洋区现有四亚区的另一亚区,主张古北区和东洋区在我国东部的分界线约在北纬35度左右。还对等翅目中文定名作了建议。
