Abstract:[Objective] The water status and utilization potential of the non-growing growing season on the Loess Plateau were analyzed to provide reference for the efficient utilization of water resources in the process of ecological environment construction. [Methods] Data from meteorological stations in Loess Plateau and test in situ was used to analyze the status of water and heat during non-growing season. [Results] Plants in most parts of the study area go through spring germination and autumn dead process. Soil has freeze-thaw cycles with the maximum frozen depth of 186 cm. And there is a certain amount of snowfall and the maximum snow depth record is 30 cm. On average, precipitation during non-growing season accounted for 7.7% annual precipitation. In the north area of Shaanxi Province, the freezing time of typical observation field station is up to three months. [Conclusion] Water and heat should be studied and use efficiency of the limited water resources should be improved. It is very important for vegetative restoration in the region.
