摘　　要：黄河流域盐碱地分布广泛、盐分含量高,黄河上游盐渍区域主要分布在河套平原、黄土高原和鄂尔多斯高原,中游主要分布在银川平原及内蒙古自治区的后套和中滩三个冲积平原,下游主要分布在河南和山东沿黄灌区以及黄河三角洲的渤海滨海盐渍土,面积约为206.44×10^(4)hm^(2),造成了严重的土地退化和农业生产问题。本文旨在探讨黄河流域盐碱地资源的现状与保护利用策略,概述了黄河流域盐碱地资源的特点,包括面积分布、土壤盐分性质和形成原因;深入分析了流域上中下游及三角洲地区盐碱地的开发利用现状;提出了一套针对不同盐碱地类型的保护利用策略,为黄河流域盐碱地资源的可持续利用提供理论和技术支撑。The Yellow River Basin has a wide distribution of saline-alkali land with high salinity,cover-ing an area of approximate 206.44×10^(4) hm^(2).The saline-alkali areas in the upper reaches of the Yellow River are mainly distributed in the Hetao Plain,the Loess Plateau and the Ordos Plateau.In the middle reaches,they are mainly distributed in three alluvial plains including the Yinchuan Plain,and the Houtao and Zhongtan plain in Inner Mongolia Autonomous Region.In the lower reaches,they are mainly distributed in the Yellow River irrigation areas in Henan and Shandong provinces as well as the saline-alkali soils along the Bohai Sea coast of the Yellow River Delta.This has caused serious land degradation and agricultural production problems.Aimed to explore the current status and conservation and utilization strategies of saline-alkali land resources in the Yellow River Basin,the article overviewed the characteristics of saline-alkali land resources in the Yellow River Basin including distribution,soil salinity properties and causes of formation,deeply analyzed the devel-opment and utilization status of saline-alkali land in the upper,middle and lower reaches of the basin,as well as in the delta region,and proposed a set of conservation and utilization strategies for different types of saline-alkali land,hoping to provide theoretical and technical supports for the sustainable utilization of saline-alkali land resources in the Yellow River Basin.
