摘要
洪积扇分布面积小则数平方米,大则几十上百平方公里,分布厚度由几米到几十米,甚至几百米。由于其分选性差,成分复杂,结构较松散,含水较丰富,有利于植物的生长发育,有利于农业生产的耕作和耕种,因而对人类的生产和工程活动以及经济社会发展具有重要意义。从地质构造和气候入手对洪积扇的形成和发展进行了分析,并针对不同类型的洪积扇提出了开发利用和处理措施。
Distribution areas of proluvial fan are from several square meters to more than one hundred square kilometers, the thickness are from several meters to hundreds meters. Because of its low sorting, complex composition and high water cut, it is beneficial to the growth and development of plants, and has important significance in human beings＇ production and engineering activities. Starting from geological structure and climate, we analyzed formation and development of proluvial fan, and put forward suggestions of utilization and treatment measures aimed at different types of proluvial fans.
