摘要
为了有效控制草地退化,保护生物资源,保持"生态—经济—社会"的良性循环和生物资源的可持续利用。通过在希拉穆仁草原典型地带进行不同材料覆盖的土壤蒸发实验,并以恢复生态学为指导思想,研究了不同材料覆盖对土壤水分的影响。试验结果表明,干草、砾石覆盖均能有效地抑制土壤蒸发,相比对照而言,整个蒸发过程中,干草覆盖比砾石更能有效抑制土壤水分蒸发。
The study was designed for the purposes of controlling grassland degradation, protecting biological resources, and keeping a benign cycle of ecology, society, and economy. With restoration ecology as a guide, a soil evaporation experiment was conducted to analyze the effects of different material covers on soil mois- ture in the typical steppe zone. Results show that gravel and hay covers can effectively inhibit soil evapora- tion. The inhibitory effect of hay covers is more significant than gravel in the whole evaporation process.
