Abstract: The experiment of desertified lands' agricultural development has been conducted in Yanjing county of Henan Province which situated in semihumid region.The results of observation,test and sample analysis show that great ecological effect has been obtained through desertified lands' reclaimation and utilization.In details,sand-drift activity has been controlled,and sand damages have been prevented;the productivity of desertified land has been retaind and heightened;the micro climate in spot has been improved.As results of all these efforts the reversion of land desertification in the studied area has been achieved.

Key words: Semihumid region, Desertified land, Reclaimation and utilization, Ecological effect
