The natural distribution status of common afforestation species in Wang Longgou Basin,Yi Count,Taihang Mountain were surveyed,and the correlation analysis between the percentage of palisade tissue in different tree species leaves thickness and the soil water content were studied.The results showed that different tree species distributed concentrately in the different regions of the hilly,and there was a very significance negative correlation between different percentages of palisade tissue in different tree species leaves thickness and the soil water content,that is to say,the higher the percentage of palisade tissue in leaves thickness was,the stronger the drought tolerance of the plant was.
