| ：以黄河流域半湿润偏旱区14个国家级土壤湿度站点资料为数据基础,以Su fer7.0为技术手段,分析代表站点多年平均和不同降水年型的土壤水分动态变化规律,以期为研究区域节水高效农业的建设提供科学依据。 |
| 英文摘要: |
| Soil moisture is an important basis of land sustainable use and water resource planning and management,and it has become one of the research hotspots in the world.According to the data of soil water at 14 national stations,this paper analyzes the seasonal and vertical variations of soil water contents in typical sites during the last 20 years and in different precipitation years by means of Sufer7.0 technology.The results and conclusions will provide scientific guidance to the development of high-efficient water-saving agriculture in the semi-humid area prone to drought in Yellow River valley. |
