摘要: 为了研究生态毯覆盖对土壤湿度和养分的影响,首次将生态毯应用于地震滑坡区砾石泥沙堆积区和泥沙堆积区。结果表明:铺设生态毯的土壤含水量均高于裸地的;各层的土壤水分含量随干旱日数的增加呈下降的趋势,生态毯的下降趋势较为平稳;保水效果为椰纤维生态毯 > 秸秆+椰纤维生态毯 > 秸秆生态毯 > 裸地。覆盖生态毯可以提高土壤有机质含量和pH值;土壤速效N、P、K和全N、全P、全K的含量也有一定程度的提高。铺设生态毯能有效固定地震滑坡区的砾石泥沙,改善土壤的水热条件,进而增加根系、微生物的活动和植被有机体的积累,促进枯落物的分解,逐步提高土壤中的养分含量。

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.
