Abstract Children love books, and through carefully chosen ones geographic concepts can be conveyed. Books are good resources—great background material for describing a place, emphasizing the culture of a region, highlighting a geographical issue, or clarifying where a place is in the world. This article explains how literature encourages geographic thinking, builds geographic skills, and develops lasting mental maps of places and regions. 相似文献

Norsk geografisk Tidsskrift inneholdt i 1928 (B. II, s. 55) en tabell over 60-årsmidler av lufttemperatur i Norge for 110 stasjoner. De fleste av disse var eldre stasjoner fra tiden før 1915. Men i årene omkring 1920 blev der oprettet en mengde nye stasjoner til hjelp for den nye værvarsling, og disse stasjoner har nu været i virksomhet ca. 10 år, så at det kan lønne sig å beregne normalverdier også for dem. Dette arbeide har vi utført i fjor, og det omfatter 82 stasjoner. Tabellene er arrangert på samme måte som tidligere. For hver stasjon angis de geograflske koordinater: nordlig bredde, lengde E. Gr. og hoiden over havet, videre de 60-årige middeltemperaturer for de 12 måneder og for aret, samt endelig en kolonne, som angir antall observasjonsår. Temperaturene for den varmeste og koldeste maned er fremhevet ved fete typer. I de forrige tabeller har vi funnet en feil, som bedes rettet: Lindesnes oktober star angitt som 7.6; det skal vaere 8.4. Og stasjonen Ingoy har vi mattet trykke om igjen, da den nye beregning stotter sig på 91/2 års observasjoner, mens den gamle bare hadde 4 år. 相似文献

Palaeolimnological and palynological records from climatically variable central Alberta, Canada, document periods of hypersaline lake conditions indicative of late glacial and early Holocene drought. The sensitivity of palaeolimnological indicators for inferring palaeoclimates is examined by comparing records from two sites at opposite ends of the regional precipitation gradient. Palaeosalinity is identified by the presence of Ruppia pollen, a hypersaline aquatic plant not presently growing in either lake, and diatom assemblages comprising both saline epipelic and planktonic species. Goldeye Lake (52° 27 N; 116° 12 W), in the relatively moist Rocky Mountain Foothills remained saline from its inception before ca 14500 years BP until ca 10400 years BP by which time pioneering forests had replaced tundra vegetation; however, freshwater planktonic diatoms dominated ca 12500 to 11500 years BP. However, dating problems endemic to the Foothills region make this chronology only tentative. Moore Lake (54° 30 N; 110° 30 N), in dry, east-central Alberta contained Ruppia only between ca 9000 and 6000 years BP. Freshwater diatoms dominated until ca 10000 years BP when they were succeeded by taxa characteristic of saline water. The lake remained saline until ca 6000 years BP. The late glacial period of palaeosalinity at Goldeye Lake occurred because the lake was surrounded by Cordilleran and Laurentide glacial ice, and therefore, cut off from moisture sources until the early Holocene by which time significant ice recession had occurred. Factors causing the second period of salinity remain unknown at this time. In contrast, by the early Holocene, Moore Lake was influenced by drought caused by high summer insolation induced by orbital fluctuations. Freshwater conditions were maintained through the Holocene in the Foothills region of west-central Alberta, but occurred consistently only over the last 4000 years in central and east-central Alberta. The warmer, drier climate during the early Holocene did affect lake levels in at least one headwater Foothills lake (Fairfax Lake — 52° 58 N; 116° 34 W). The severity of the drought increased in an easterly direction across the province.This publication is the fourth of a series of papers presented at the Conference on Sedimentary and Palaeolimnological Records of Saline Lakes. This Conference was held August 13–16, 1991 at the University of Saskatchewan, Saskatoon, Canada. Dr. Evans is serving as Guest Editor. 相似文献

On the basis of the geological mapping, isotopic choronoogcal and petrological evidences, the aumors suggested that the early Tertiary volcanic strata in the Fildes Peninsula could be divided into two formations and four members. The erupted centers in the peninsula were gradualy migrating from the western coast to the eastern and the subvolcanic intrusives were regularly distributed along a series of NWW-SEE trending faults. All of these were basically formed in two stages of volcanic activities from Paleocene to Eocene. 相似文献

The behaviour of the ice-dammed lake, Strupvatnet, Troms County, Norway, is described. Past observations are noted and related to observations in 1959 and to other ice-dammed lakes. Mechanisms for opening and maintaining water flow during a ‘hlaup’ are discussed. It is considered that Liestol's melt widening process operates after initiation by a pressure gradient across the dam. The lake and the internal drainage system of the glacier are thus linked. There is no evidence of lifting of the ice dam at Strupbreen. 相似文献

广州市流动人口管理研究—现状,预测与对策 总被引：5，自引：0，他引：5
广州市是我国流动人口最多的大城市之一，其流动人口具有来源地广泛、目的多样、性别比高、年龄构成轻、文化素质不高以及滞留时间长的特点。现在，流动人口的劳务、计划生育和社会治安管理中存在着诸多问题。１９７０年到１９９３年，广州市流动人口以每年平均１５．１８％的速度增长。为了预测其未来的发展趋势，本文根据灰色系统理论，建立ＧＭ（１，１）模型。该模型精度较高，通过检验，依据此模型对未来５年内广州市流动人口进 相似文献
