【摘要】 对天山北麓平原细砂、砂砾石、粉质轻粘土等三种代表性岩性的地层进行了凝结水的观测试验,分析研究了土壤剖面温度变化特征、凝结水形成的水汽来源、产生凝结水的深度和时间、积雪期雪面的水汽凝结、冻结层水汽凝结、蒸发作用和潜水埋深等因素对水汽凝结的影响、凝结水的数量及其生态环境效应。研究成果对西北干旱地区耐旱植被的研究和生态环境建设具有重要意义。更多还原

【Abstract】 Based on experiments on coagulating water within the strata of fine sand,gravel sand,and silty clay in the plain on the northern slope of the Tianshan Mountain,the authors obtained a series of valuable information,such as the characteristics of temperature variation in soil section,the vapor source of coagulating water,the formation time and depth of coagulating water,the vapor coagulation on snow surface during snow-cover days,the vapor coagulation in the frozen layer,the effect of evaporation and water table on vapor coagulation,the coagulating water quantity and its effect on ecological environment.The results of this study are most valuable in the investigation of drought enduring plants and the construction of a favorable ecological environment in northwest arid region.更多还原
