逆插支流的演变与河流掉向的关系

RELATIONSHIPS BETWEEN ENVOLUTION OF REFLUENT TRIBUTARY AND RIVER REFLUENCE

逆插支流是相对正插和顺插支流而言，它们之间的演变过程，受到新构造运动、流水地质作用等诸因素的影响。尤其是逆插支流的演变，对主干河流是否掉向，意义重大，但不是所有逆插支流都对指示主干河流掉向有意义。试图从演变的角度，来剖析逆插、正插和顺插支流的内在联系，以求探讨上述问题。

Amony the processes influencing the river evolution the neotectonism as well as fluriation is one of the most important.The impact of the occurence and development of neotectonism and fluoiation on river evolution was evaluated in this paper,especially on the refluent river evolution.Classification of the refluent river was made according to genesis and characteristic of the refluent river.The pap suggests that not all of refluent tributary play important role in river evolution.On a basis of evolution,the inner link between the refluent river and the coseguent river is described in this paper.So study on the relationships between the refluent and the river refluence is of great sigm ficance.
