摘要
在流动沙丘迎风坡覆盖生态垫后,通过对土壤水分和温度的连续观测发现:在生态垫覆盖林地的生长季内,表层0—20 cm的土壤温度和20—60 cm的土壤含水量受覆盖影响最明显。覆盖与未覆盖生态垫的流动沙丘相比,可提高20—40 cm处土壤含水量为56%,提高40—60 cm处土壤含水量58%;7月可降低土壤表层温度14.27℃,且覆盖后土壤各层之间温度变化平缓,对10 cm以下土壤有保温作用。
One-year-period monitoring for soil water content and soil temperature in windward slope of moving dunes with eco-mat mulch proved that compared with the CK the eco-mat mulch might enhance the soil moisture content by 56% within 20-40 cm depth,enhance the soil moisture content by 58% with 40-60 cm depth;whereas,reduce the eco-mat mulch might reduce the soil surface layer temperature by 14.27℃ in July,besides,the soil temperature vary gently between soil layers and the eco-mat had obvious effect of heat and soil moisture conservation below 10 cm soil layer.
