摘要
通过观测典型农牧交错带-内蒙古太仆寺旗的秋翻地、春翻地、留茬地、风蚀劣地以及草地等7种不同地表土壤水分的变化特征,研究不同地表对土壤水分的影响。观测结果表明,农田休闲期,秋翻地与油菜茬地土壤的蓄水保墒能力较强,草地与风蚀劣地土壤的蓄水保墒能力较差,其它几种地表居中。
Through field investigation of soil moisture on soils of different surfaces,the effect of different soil surface on soil moisture was disclosed. The results indicated that in the farming-pastoral ecotone, water storage and retention was increased in autumn-ploughed farmland and rape stubble farmland, and water storage and retention was decreased in grassland and deteriorated land.
