摘　　要：在黄河三角洲地区进行的一系列造林抑制土壤返盐的试验表明:林分郁闭度与抑盐作用正相关;林木对其一定范围内的土壤有抑盐作用;农田林网对抑制土壤返盐有显著作用。在此基础上,探讨了林木抑制土壤返盐的原因。提出在黄河三角洲地区广泛造林,同时配合良好的水利建设,是抑制土壤返盐,延长土地利用时间的有效措施。A series of forestation tests for controlling soil secondary salinization were conducted in the Yellow River Delta Saline lands. The results showed that the stand canopy density had a positive correlation to the control of soil salinization and forest trees played the control role on soil salinization within a certain range. The farmland sheherhehs had a significant effect on soil salinization control. On the basis, this paper explored the causes of controlling soil secondary saiinization by forest trees and put forward some measures for controlling soil secondary salinization by extensive forestation in the Yellow River Delta regions.
