La République Populaire de Chine n'a adopté que récemment la théorie des lieux centraux. L'A. étudie une région du Sichuan et montre l'importance des centres ruraux en étudiant aussi bien les marchés périodiques que les installations permanentes
La réforme administrative de 1952 avait instauré une hiérarchie des lieux centraux dans l'ex-RDA. Depuis la réunification, le changement de structure économique entraîne une modification dans la fonction et l'importance des lieux centraux. - (D
Fault-generated mountain fronts in the central Apennines (Central Italy): geomorphological features and seismotectonic implications
Normal fault-generated mountain fronts are a characteristic element of the landscape in the Central Apennines. The purpose of this work is: 1) to recognize the recent activity of the tectonic structures responsible for their formation; 2

L'A. étudie l'amélioration des services ferroviaires depuis 40 ans et l'essor de la circulation routière dans le Massif Central. L'enclavement n'est plus une réalité et l'A. se demande si les investissements autoroutiers sont justifiés.
The paper focuses on five villages in the Mourdiah Nara area of north-central Mali. The A. explores the strategies to cope with the dry season and proposes those strategies which may be most suitable for development into assistance programmes

The basic steps in constructing choropleth maps are followed by a discussion of how such maps might be used in a secondary school lesson using Mexico, Central America and the Caribbean as a case study. The A. argues that the value of making
Ecology and agricultural development in four villages of Central Karnataka
In Central Karnataka the farmers have for a long time adjusted their farming methods and strategy to ecological conditions, seasonal distribution and variability of precipitation and soils. This study concerns four villages. The crop composition
Holocene paleofloods of the Ross River, Central Australia
The AA. describe the alluvial stratigraphy of a central Australian river downstream from its headwater drainage area and at the point where it exists from its gorge section on to a broad floodplain. They also illustrate how that stratigraphy can
Radiocarbon ages of soils and charcoal in Late Wisconsinan Loess, South-Central Nebraska
The purpose of this paper is to present radiocarbon ages and soil-stratigraphic data for the lower few meters of Peoria loess in south-central Nebraska.
Late Quaternary environmental and climatic changes in Central Brazil
Paleoenvironmental changes dating back to 30,000 yr B.P. documented in a pollen record from central Brazil (lat. 19o S) permit the reconstruction of climatic changes related to shifts of the Antarctic polar fronts. The paleoclimatic inferences were

Tree-growth response to Enso events in the central Colorado Front Range
The inflence of climate associated with El Niño/Southern Oscillation (ENSO) events on tree growth in the central Colorado Front Range is investigated through the analysis of two high altitude tree-ring chronologies. Dendrochronological techniques
are used to determine if ENSO-related climatic effects are detectable in tree-ring width patterns in the central Colorado Front Range. The form of the tree growth response is identified and the variability of the influence of these events on tree growth
