Amelioration of saline-alkali land and its utilization is a hot and important topic inChina. In this paper, some successful case study examples for saline-alkali soil amelioration were summarized, like vertical drainage combined with drip irrigation under plastic mulch method and other alkali- saline soil treatment methods. The amelioration and utilization method for saline-alkali land combined vertical drainage and groundwater utilization in Weigan River irrigation district was proposed. It showed an obvious effect in saving water and land amelioration. This engineering practice promoted the planning work of alkali-saline land amelioration in Tarim Basin, and also provided a demonstration model for other regions.
