Abstract:: The surface soil moisture is very important index of flooding and drought forecasting,soil erosion,crop yield estimation and environmental disaster monitoring.With the north Ziwu ridge natural second growth and Luochuan rural section as the research area,we analyzed seasonal changes of index of the surface soil moisture and the surface soil moisture index on precipitation conditions between the two areas.The results showed that:forest surface soil moisture index overall significantly higher than rural section;by precipitation influence,response time of the rural section surface soil moisture was short,and surface soil moisture content increased more quickly.After precipitation,in the same surface soil moisture,the forest surface soil moisture can drop to a certain level later than rural section for 10 days.Or,in the 10 days,the forest surface soil moisture lost less than rural section for 50 percents.
