摘要 本文对柴达木盆地的农业自然条件进行了分析 ,并对光合生产潜力、光温生产潜力、光温水(气候 )生产潜力及灌溉调节后的光温水生产潜力进行了计算 ,在此基础上 ,对提高柴达木盆地农业生产潜力的主要措施进行了讨论。 This paper analyses the agricultural natural conditions of the Qaidam Basin,an inland basin with high altitude in arid lands of China,calculates the potential productivities of photosynthesis,of the light and temperature,of the light,temperature and water (climate),of the light,temperature and water regulated after irrigation as well as changes of crop yield from 1990 to 1996,and puts forward the principal measures for improving agricultural potential productivities of the Basin.The specific measures include: 1)to develop water saving irrigation,construct irrigation systems by combining diversion with drawing and irrigation with drainage; 2)to establish evaporation decrease and temperature increase cropping systems by means of reducing evaporation in the inter planting field with straw and plastic canopy; 3)to breed and popularize fine crop varieties; and 4)to strengthen construction of shelterbelt systems,improve eco enviroment and raise actual potential productivity.
