Abstract:

In order to study the influence of soil characteristics on herbaceous vegetation layer in mountains,the correlation between herbaceous biomass,herbaceous plant diversity and soil factors in arid sunny slopes of mountainous areas in northern Hebei was studied.The results showed a clear correlation between the herbaceous biomass and herbal height(r=0.351,P<0.01,n=132);herbaceous biomass and soil thickness has a significant positive correlation(r=0.351,P<0.01,n=132)(P<0.01),herbaceous biomass and stone coverage has a clear negative correlation(r=0.297,P<0.01,n=132),but no significant correlation with soil nutrient.There was a negative correlation between species richness and soil nutrients,but it was significant only for total nitrogen,available phosphorus content.It is concluded that the soil thickness plays a great role in herbaceous biomass in arid sunny slopes of mountainous areas,and soil nutrient is not the limiting factors in herbaceous production,while high soil nutrients lead to decrease in species richness.

Key words: mountains of northern Hebei, sunny slope, biomass, soil factors, herb
