1998's floods in the Changjiang River and the land use/land cover change in the upper and middle-lower reaches in the past 50 years
Flood of Changjiang River (the Yangtze) in 1998 was so serious that it arose a keen concern about its causes. In this paper, the AA. bring out a brief history of the flood disaster happened to the Changjiang River Valley in the last six centuries
and analyze the causes for the frequent flood disasters based on the land use and land cover change in the upper and middle-lower reaches of the Changjiang River.
ST The paleoenvironment of the mid-lower regions of Changjiang in the full-glacial period of late Pleistocene
L'A. analyse les éléments sédimentaires et les informations paléontologiques dans la région du Changjiang moyen et inférieur, de 18000 ans BP à nos jours, pendant le pléniglaciaire. Description des principaux éléments naturels comprenant les
Bedforms and bed material transport pathways in the Changjiang (Yantze) Estuary
This study aims to investigate the bed features in the tide-dominated Changjiang (Yangtze) Estuary using a side-scan sonar and a depth recorder, and to examine the bed material transport pathways on the basis of the maximized gross bedform-normal
to effectively determine the bed material transport directions in the Changjiang Estuary.

Le Changjiang (6 300 km) et le Huanghe (5 464 km) sont les deux plus grands fleuves d'Asie de l'Est. L'article traite de ces deux géants chinois d'une part du point de vue hydrogéographique, d'autre part du point de vue de l'utilisation des

There are over two thousand urban settlements within the Changjiang Delta area and a large and complex system of urban places with different functions is distinguishable. The four large cities have clearly functioned as development poles

From sediment samples collected in the lower reach of Changjiang River (from Nanjing to Shanghai), the AA. examine the correlation between heavy metals and geochemical indices, including Fe2O3, Al2O3, total organic carbon (TOC) and black carbon (BC
and multivariable statistical methods clearly characterizes the geochemistry of heavy metals in sediment of the lower reaches of the Changjiang River and suggests that power plants are the main source of heavy metal pollution.
The use of reflectance visible–NIR spectroscopy to predict seasonal change of trace metals in suspended solids of Changjiang River
Diffuse reflectance visible and near infrared spectroscopy (Vis/NIR) was used to analyze the trace metal content of suspended solids collected from the Changjiang River during different seasons and to compare concentrations between the main river
Le développement urbain du delta de Changjiang entraîne une profonde transformation de l'utilisation du sol. La télédétection permet d'analyser de façon précise le développement des espaces industriels et de l'habitat ainsi que la consommation de
Since the anabranched river pattern is the most typical one in the middle and lower reaches of the Yangtze River (Changjiang) as well as in many other rivers in China, a systematic study on the formation cause of the anabranched river pattern has
