Abstract: In order to study the effect of eco-blanket covering on soil moisture and nutrients,the eco-blanket is firstly applied to the gravel sediment accumulation area and sediment accumulation area in landslide areas caused by the earthquake. The results showed that the moisture of soil covered with the eco-blanket was higher than that of bare oil; the moisture content of each layer soil was downward with the number of drought days increasing,while the declining of the soil covered with the eco-blanket was relatively stable; water retention effect was as follows:coconut fiber eco-blanket > straw + coconut fiber eco-blanket > straw eco-blanket > bare land. The eco-blanket coverage could increase soil organic matter content and pH value; soil available N,P,K and total N,P,K content also improved to some extent. Laying the eco-blanket could fix the gravel sediment effectively in landslide areas caused by the earthquake and improve soil water and heat conditions,thus increasing the activity of roots and microbial and the accumulation of vegetation organisms,promoting the decomposition of litter,and gradually improving the soil nutrient content.
