摘要
本文根据１９８８－１９９０年的定位观测资料，对晋西北黄土丘陵区的河北杨林、刺槐林和柠条灌木林的土壤水分动态规律进行了定量分析。依次就水分分布分层、水分剖面特征、水分季节动态、水分循环模式与水分循环水平等问题进行了探讨。本文采用的新的分析途径和方法将有助于时黄土区不同植被类型土壤水分生态研究的进一步深化。
ased on the 1988-1990 data of field monitoring,an analysis was made on the soil waterdynamics of Populus hopeiensis,Robinia pseudoacacia and Caragana korshinskii Plantations inthe loess plateau region in Northwestern Shanxi,by examining the following issues:the stratification of soil water distribution,the characteristics of soil water profile,the soilwater seasonal dynamics,the water cycle model and water cycle level.The new analysismethod used in this study can facilitate the further researches on soil water ecology for vari-ous types of vegetation in the loess plateau region.
