北京地区3种典型质地土壤水分变化规律
Soil Moisture Varlation of Three Typical Soil Textures in Beijing Area
摘要
Abstract
[Objective] The research aimed to study the soil moisture variation ofdifferent soil textures in Beijing area.【Method】The data of soil moisture in recent five years Was obtained, and three typical soil textures in Beijing area were observed.【Result]The average moisture colltent of chy soil Wma higher than that of loam soil.Followed by sand loam soil.The analysis of seasonal changes in soil moisture indicated that soil moisture increased slighdy in early spring, then decreased through the spring,and experienced another ihcrease and decrease from rainy season to fall.In rainy season, the rainfall and evaporation had significant effects on moisture content of sandy loam, and less effects on chy.[Conclusion]The seasonal variation in soil moisture of different soil textures was generally similar in unfrozen phase , and the soft mois-ture was mainly affected by the precipitation.关键词
