Water Level Change and Human Activity in the Amazon

本研究的目的是分析和解释亚马逊河滩地河流水位变化与人类活动之间存在的关系。将收集亚马逊中部(马瑙斯)和河口(贝伦)之间的河岸地区的数据，那里的居民活动被认为受到河流水位波动的影响最大。现有资料表明，Obidos以上的水位波动受年度降水制度的控制。另一方面，在河口，与潮汐制度相关的日振荡比季节性降雨制度带来的变化更明显。这项研究的具体目标是：1)在建议的研究区域内获得沿海泊点的精确水位测量；2)解释河流水位的季节和日变化对人类活动的影响，特别是对他们的经济和社会的影响。结果发表在Re…上1.亚马逊河口Abaetuba、Breves和CaxiuanaNoboru Hida(秋田大学)、Jose Guilherme Maia(巴西Goeldi博物馆)、Mario Hiraoka(美国Millersv大学)、Osamu Shimmi(Kagawa大学)站的亚马逊河口的年度和每日水位变化。和Nobuaki Mizutani(Ltd.nissaku)2.马瑙斯、巴西Noboru Hida、Jose Djalma C.de Araujo(Admin.do Porto de Manaus)、Nobuaki Mizutani和Osamu Shimmi3.陆地卫星TM图像上的亚马逊水域西田真本(Akta Univ.)和Yoichi Kageyama(秋田大学)4.Amazon varzeaJose Guilherme Maia5.非木材天然产品。人类对亚马逊中部和河口泛滥平原不断变化的生态和经济的适应。里约热内卢亚马逊的水位变化和瓦泽亚景观Osamu Shimmi和Noboru Hida这些手稿很快就会在一些期刊上发表，并被授权作为一种研究书籍的风格。较少

The objectives of this study are to analyze and explain the relationship that exist between reiver level changes and human activities on the floodplain of the Amazon River. Data will be gathered on the riparian area between the Middle Amazon (Manaus) and the estuary (Belem), where the inhabitant' activities are believed to be most influenced by the fluctuations in river levels. Existing information suggest that water level fluctuations above Obidos are controlled by the annual precipitation regimes. On the other hand, in the estuary, the daily oscillations associated with the tidal regime are more pronounced than the changes brought about by the seasonal rainfall regimes. The specific goals of the research are : 1) to obtain precise water level measurements along seberal points within the proposed study region ; 2) to explain the influences of seasonal and daily fluctuations of river water level on human activities, especially their economy and society.The results were offerd in the re … More search meeting : "Time-space analysis of water level changes and their impacts on human activities in the middle and lower Amazon" to be held in the Faculty of Education, Akita University on December 2,1996 in the following presentations :1.
