渭干河流域竖井排灌盐碱地治理与地下水开发

Saline-Alkali Soil Amelioration and Groundwater Utilization Using Vertical Drainage Method in Weigan River Irrigation District of China

摘要: 盐碱地改良和资源化利用正在受到前所未有的重视。本文通过总结竖井排灌结合膜下滴灌工程等改良盐碱地等成功实例，提出了渭干河流域竖井排灌与地下水开发利用相结合的盐碱地改良利用模式，盐碱地改良及节水效果明显，促进了塔里木河流域盐碱地改良规划的具体实施，也为各地盐碱地改良利用提供了良好的示范作用。

Abstract:

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.
