摘要
通过分析塔里木河水沙条件、遥感地形河势资料 ,作者深入研究了塔里木河干流河道的河型及其成因 ,指出和论证了塔里木河干流河道存在着游荡型、弯曲型和过渡型三种河型 ,阿拉尔至沙雅县鹿场附近河段 (新其满河段以上河道 )为游荡型河道 ,新其满下游的曲毛格金至恰拉水文站 (新其满河段以下河道 )为弯曲型河道 ,恰拉以下属于不规则的弯曲型 (微弯 )河段 ,沙雅县鹿场至曲毛格金河段 (新其满河段 )属于过渡性河段 ;河道边界条件和来水来沙条件仍是决定塔里木河河型的主要因素 。
Based on the hydrologic data and river regimes by aerial survey,the river patterns and their causes of formation in the trunk channel of the Tarim river were studied in this paper. The study shows that Tarim river can be divided into three river patterns: the wandering stream,meandering stream and transitional reach,of which the wandering stream,meandering stream and transitional reach are respectively located in the upper reach of Xinqiman(from Alaer hydrographic station to the Deer farm in Shaya county,Xinqiman is also a hydrographic station),the Xinqiman reach (from Deer farm to Qumaogejin) and the lower reach of Xinqiman (from Qumaogejin to Qiala hydrographic station).The lower reach downstream Qiala hydrographic station could be called as a developing meandering stream because of water shortage.River boundary and the oncoming flow and sediment,such as the dense and sparse vegetation by shrub and diversiform\|leaved poplar, flooding, and diversion in the both sides of the Tarim river,are very important factors in the formation of the river patterns.
