| 摘 要： | 试验于１９９１－１９９４年在固原上黄试区柠条、沙棘、山桃灌木林地进行，通过对３种灌木蒸腾强度和生长期和生长末的日变化，以及这些变化与环境因子的关系的研究，有助于了解不同灌木树种在半干旱条件下对水分的需求，并对大力发展和合理经营灌木林，充分发挥灌木林的多种生态经济效益提供科学依据。

| Abstract: | The experiment was carried out at the land shrub forest(Caragana korshinskii,Hipphae rhemnoides,Prunus davidiana) from 1991 to 1994 at Shanghuang Experimental Feild inGuyan county.This paper studied the daily changes of transpiration rate at growth period and theend of growth of three species,and the relationship between these changes and enviroment factor.Itwill contribute to understande demaned of water of different species of shrub at semi-arid condi-ton.and provide the scientific basis for energetically developing and reasonable managing shrub for-est, and also for bring ecological and economic benefits of shrub forest into full play. |
