新疆叶尔羌河平原绿洲洼地旱排作用的初步分析

Preliminary Analysis on the Dry Drainage Rffect of Low lying Lands in Yerqiang Oasis in Xinjiang

通过对新疆叶尔羌河流域平原绿洲一个典型洼地水量平衡的观测和计算，分析了洼地在容泄绿洲排水、排盐方面的旱排作用及排水、排盐能力。提出在绿洲排水规划时，可将旱排（或内排水）作为一种重要的排水方式，选择合适的洼地作为主要的旱排规划区。

Through the water balance observation and calculation to a typical low lying land in the oasis of Yerqiang River Basin in Xinjing,the drainage effect and drainage capacity of the low lying land in the oasis were analyzed.Moreover,it is proposed that dry drainage can be taken as an important way for the drainge of water and salt,and suitable low lying land should be chosen as the main dry drainage area in the drainage planning of oasis in raid area.
