　　平罗县地处宁夏引黄灌区末端,盐碱地面积大、含盐量高、造林难度大。平罗县未利用盐碱地面积为49.5万亩，占未利用土地总面积的53.52%。盐碱土地区由于含盐量较高，大多为不毛之地，PH值在7.7-10.2之间，矿化度在1.8-9克/升之间，因此，加强对其改造势在必行，本文介绍了改造盐碱地的六种方式：重盐碱地造林、盐渍化稻区农田林网、盐碱滩地造林、中度盐渍区荒地及耕地改良发展经济林、轻度盐碱荒地改造发展灌木林、低洼盐碱沙地利用红柳扦插造林。

Pingluo County is located in the terminal of Ningxia Yellow River irrigation area. It has the caractersitics of large saline-alkali land area, the high salt content, and afforestation difficulty. The unused saline-alkali land in Pingluo County is 495,000 mu, accounting for 53.52%of the total area of unused land. Because of the high salt concentration, saline-alkali land area mostly are wasteland, pH value is between 7.7-10.2, the degree of mineralization in the 1.8-9 g/L. Therefore, to strengthen the reform is imperative. This paper introduces six kinds of transformation mode of saline-alkali soil: heavy saline-alkaline soil is used to plant trees, salinization of farmland forest, afforestation in saline-alkali land is for afforestation, moderate saline area of wasteland and the cultivated land is improved and developed economic forest, mild saline-alkali wasteland is reformed and develop to shrubwood, the low-lying saline-alkali shrub sand is use to plant rose willow for forestation.
