摘要
通过白音花沙地草牧场防护林下的土壤水分变化分析得出:草牧场防护林保护下的土壤水分随季节变化呈现明显的周期变化,距林带不同距离及不同土壤深度的土壤水分变化也不同。研究表明:草牧场防护林不仅提高了其防护范围内的土壤水分,改善了土壤水分供应状况,而且可有效调控沙地土壤水分,提高沙地生产力。
Soil moisture changes in sandy grassland with sheherbelts in Baiyinhua were analyzed. Result shows that the soil moisture changes with changes of seasons, the distances to shelterbelt, and soil depths; the shelterbelt increases not only soil moisture ,but also grassland productivity.
