In the field of economics, it is used as a translation of the word "hinterland." Originally, it was used to refer to the area where the economic functions of a port extend, but the meaning has expanded to include not only the economic functions of a port but also the economic functions of a city in general, as well as the range of social functions (commuting, going to school, shopping, going to the hospital, etc.), in other words, the urban area. The relationship between ports and cities and their hinterlands is mutually determining, and as port and city activity increases, the hinterland expands accordingly. The hinterland also fulfills a culture function that supports the port or city economically and socially, so if the activity of the hinterland becomes inactive, the port or city's influence will also weaken. [Yukio Asaka] In sedimentology, a branch of geology, it refers to the source area that brought sediments to a sedimentary basin, i.e. the land behind it. If the deposited sandstone layers contain a large proportion of quartz and feldspar particles, it is assumed that the land that brought them had exposed granite. In such cases, the expression "granite was exposed in the hinterland of the sedimentary basin" is used. In structural geology, it also refers to the area inside the orogenic belt, on the opposite side of the direction of the fold or thrust, in the fold belt or thrust fault zone at the edge of the orogenic belt. On the other hand, the area beyond the thrust direction and outside the orogenic belt is called the foreland.

経済学の分野ではヒンターランドhinterlandの訳語として用いられる。本来は港の果たす経済的機能の広がる地域をよぶことに始まったが、現在は語義が拡大されて、港のみならず広く都市の果たす経済的機能のほか、社会的諸機能(通勤、通学、買い物、通院など)の及ぶ範囲、すなわち都市圏をも含めていうようになっている。港や都市とそれらの後背地との関係は相互規定的であり、港や都市の活動が活発となれば、それに伴って後背地は拡大される。後背地はまた港や都市を経済的、社会的に支える培養的機能を果たすので、後背地の活動が不活発となれば、港勢や市勢もまた弱化する。 [浅香幸雄] 地質学の一つの分野である堆積(たいせき)学においては、堆積盆に堆積物をもたらした供給源地、つまり背後の陸地をさす。堆積した砂岩層に石英や長石の粒子が多くの割合で含まれていると、それらをもたらした陸地には花崗(かこう)岩が露出していたことが推定される。このような場合、堆積盆の後背地には花崗岩が露出していたという表現を用いる。また、構造地質学の分野では、造山帯の縁にある褶曲(しゅうきょく)帯や衝上(しょうじょう)断層帯で、褶曲の倒れ込む方向や衝上方向とは反対側の、造山帯内部の地域をさす。一方、衝上方向の先で造山帯の外側の地域は前縁地という。 [村田明広] [参照項目] | | | | | | | |出典 小学館 日本大百科全書(ニッポニカ)日本大百科全書(ニッポニカ)について 情報 | 凡例 |
