摘　　要：我国盐碱地面积大,华池林区水湿盐碱地长期得不到绿化,影响了整流域治理进程。调查表明,1)华池林区水湿盐碱地分布面积1090.2 hm^(2),土壤含盐量0.18%~0.26%,pH值7.5~8.2,含水量20.1%~35.6%,属轻度盐碱地;2)小叶杨、旱柳、沙柳能够自然生长在水湿盐碱地上,其中旱柳树干空心现象严重;小叶杨、沙柳生长良好,属于水湿盐碱地适生树种。Saline-alkali land covers a large area in China,the water-wet saline-alkali land could not be green for a long time,which affected the whole watershed control process in Huachi forest Area.The research shows:1) the area of water-wet saline-alkali land is 1 090.2 hm^(2),the soil salt content is 0.18%~0.26%,the pH is 7.5~8.2,and soil water content is 20.1%~35.6%.It belongs to mildly saline-alkali land;2)Populus simonii,Salix matsudana and Salix cheilophila can grow naturally on water-wet saline-alkali land,and Salix cheilophila has a serious hollow trunk;but Populus simonii and Salix matsudana grow well and belong to the adapted species in water-wet saline-alkali land.
