摘要
本文通过一系列实地土壤凝结水（包括吸湿水）测定和实验，对所得的基本数据进行综合分析，提出土壤凝结水（包括吸湿水）的主要控制因素，是土壤的机械组成，尤以＜０．００１粘粒含量为主；土壤凝结水与气象条件密切相关，与０ｃｍ、５ｃｍ、１０ｃｍ地温和气温变化呈现相同周期，与相对湿度变化有相关关系。并说明林冠下沙地凝结水量变化比裸地凝结水量小。
The comprenhensive analysis were carried out based on a series of observation data from simulates tests of soil coagulation water. The conclusion are given out follow: Mineral component particular samaller 0. 001 clay grain main influrencs soil condensation water. Soil condensation water close relates to meteorological element,and has the similar period variation with 0cm, 5cm, 10cm earth temperature and air temperature. Tell the condensation water under tree is smaller than that of bare land.
