    近年,多くの研究者によって指摘されている大都市圏の構造変化に関して,東京大都市圏周辺部への都市諸機能の集積,さらにそれらが顕著にみられる周辺中核都市の成長に着目し,1975年〜1985年の変化について考察をおこなった。個々の周辺中核都市の特性を解明するに際して,通勤・通学流動,物品販売機能の集積状況,および業務管理機能の集積状況を明らかにした。その結果は次の通りである。(1)東京への通勤・通学人口率をみると,周辺部への高等教育機関移転の結果,とりわけ通学人口率の相対的低下が進んだ。(2)通勤・通学人口率から周辺中核都市は,その人口吸引の特性によって4つの類型に分類できる。また人口吸引力に優れた機能の集積が,大都市圏周辺部において周辺中核都市を成長させている。さらにかかる都市の成長にともない人口流動現象が複雑化してきた。(3)小売商業力指数から判断して,都心部での水準維持に対して,周辺部では全体的に平準化が進み,地域格差が縮小した。また東京への通勤・通学率がおおむね30%以下と高い周辺部内帯では,東京の近郊都市としての性格を強めた結果,上記の指数の低下傾向が認められた。(4)上場企業の支所オフィスは,東京区部へ一極集中すると同時に県域統括レベル支所オフィスの周辺中核都市への著しい集積がみられた。さらに下位の都市でもその立地増加が確認された業種もある。かかる状況から,大都市圏における周辺中核都市のもつ機能は重要性を増大しつつあると言える。したがって,そうした動向は大都市圏における構造変化の一断面であると規定できる。

    Regional difference and variability of precipitation during the Baiu season (June and July) in East Asia have been studied preliminary in terms of the frequency distribution of daily precipitation and the precipitation brought about in each precipitation intensity class determined empirically. In order to demonstrate the spatial distribution of dominant daily precipitation amount (class), cluster analysis was conducted using the contribution ratios of the precipitation brought about in respective classes to total precipitation at each station using the data from 1977 to 1981. The 234 stations were classified into eight groups. Regional division was conducted based on this classification of stations. South-west Japan, Korean Peninsula and Central China Plane where the Baiu phenomenon is predominant were identified as same group. In these regions, considerable amount of total precipitation is brought about by heavy rainfalls greater than 50 mm/day. The class of maximum contribution ratio shifts heavy rainfall side with increasing of regional averaged total precipitation. Nevertheless, the class of the miner peak appears in 15-30 mm/day independently with the total precipitation amount. This fact suggests the existence of the rainfall system that causes almost the same precipitation to the comparatively rainy regions as well as the peculiar rainfall system to the region that controls total precipitation. Moreover, relationship between frequency distribution of daily precipitation and total precipitation was analyzed preliminary in terms of inter-annual variation using the data from 1951 to 1990 at Shionomisaki in the South-west Japan and Akita in North-east Japan. The result indicates that the variation of Baiu precipitation is caused not orLly by the simple variation of number of rairLfail days but variation of proportion of heavy rainfall days to total rainfall days and whether extremely heavy rainfall appears or not, corresponding to the rank of total rainfall amount. This suggests that the wide range variation in precipitation consists of multiple backgrounds that control precipitation variations of respective ranges.

    Up to this time, most of studies on children's environment perception have not taken account of some factors and phenomena in modern society preventing their development of perception of the environment. Moreover, these studies have taken only one district in one region as a study area and generalized the result, which has been made clear, as a typical case in this region. But, this case is not always applied to all regions, for one region, such as seen in a large-scale city, is divided into some districts which have different features respectively. Standing on these points, the author put the purpose of this paper on next three points. 1) To try to generalize the feature and the developmental process of children's perception of the environment in the neighborhood based on perceived amount, perceived space and perceived structure by using the analysis of their free-hand sketch-map. 2) To reveal the mechanism of development in environment perception by observing children's behavior in their living space basing on "the path of daily activity". 3) Taking account of the above two mentioned points, to try to grasp today's social and physical environment surrounding children. As a study area, the author chose Hiroshima City. This city consists of many districts which have differences in landscape and function because of city's enlarging accompanied with the affiliation of towns and villages around city. So, in studying, he divided this city into urban district, suburban district, moutain village district and island district. The main results are summarized as follows: 1) In urban and island districts, children's perceived amount increases with the advance of grade. On the other hand, in suburban and mountain village districts, their perceived amount decreases at the peak of forth grade. This is the reason why the simplification is recognized in their perception. 2) Children's perception of the environment is affected strongly by feature of the region where they live and their behavior in their living space. 3) In urban and suburban districts, children's perceived space enlarges, with the advance of grade, only in the narrow area of each school district, so their perceived space in these districts does not develop remarkably. In moutain village and island district, their perceived space spreads only around their home and reduces, in spite of the advance of grade, so their perceived space in these districts stops developping. 4) In urban and suburban districts, the neighborhood for children is limited in the narrow area of school district. In moutain village and island district, it is limited around their home. 5) In urban district, children's perceived structure develops with the advance of grade, however, in suburban district, it stops developping at the peak of forth grade. In moutain village and island district, the development of their perceived structure is unbalanced, so it dose not develop. 6) From the analysis of the path of daily activity, it is assumed that today's many social factors, such as school, cram school which is called "juku", mass media and club activity in school curricurum prevented children's daily activity, and that these preventions stopped their development of perception of the environment, in spite of the advance of grade. Finally, as a view in this study for the future, the author thinks that it is more useful to use the conception of time geography in order to analyse the prevention accompanied with behavior in detail, and to apply the results of this paper to improvement of geographical education. Furthermore, it is required that the way of free-hand sketch-map to analyse children's perception should be improved, because their sketch-map is filled with each children's peculiar character.
