- W3024509564 abstract "Cosmic-ray neutron sensing (CRNS) is a new method for measuring mean soil moisture at regional scale. On the basis of continuous observation data of CRNS and the measurements of soil moisture with the distributed sensor network in Yucheng Comprehensive Experimental Station of the Chinese Academy of Sciences, we examined the applicability of the CRNS method to the agroecosystem in North China Plain. The stability of the neutron number in dry conditions (N0) and the effects of rainfall and irrigation on soil moisture estimation were investigated. The results showed that N0 was significantly affected by the underlying surface. The changes of N0 corresponded well to the planting and harvesting time of winter wheat and summer maize. Soil moisture estimated by the CRNS method had obvious response to rainfall and irrigation. When irrigation or rainfall occurred, soil moisture was overestimated. The CRNS method could effectively estimate regional soil moisture for the agroecosystem in North China Plain. The estimates of soil moisture were closest to the soil moisture in 10 cm depth.宇宙射线快中子法是一种新兴的能够实现区域土壤水分观测的方法.以中国科学院山东禹城综合试验站的宇宙射线连续观测数据和无线网络土壤水分观测数据为基础,研究了该方法在华北平原典型农田生态系统的适用性,重点探讨了采用标定法获得的土壤完全干燥条件下中子数(N0)的稳定性和降雨灌溉对土壤水分估算的影响.结果表明: N0的变化受下垫面变化影响,变化周期与试验区冬小麦和夏玉米的种植和收割期较一致.宇宙射线法估算的土壤水分对降雨和灌溉有明显响应,但在灌溉或降雨发生时会高估土壤水分.在华北农田生态系统条件下,宇宙射线法能有效地估算区域土壤水分,估算结果与浅层土壤水分观测值(10 cm深度)最为接近." @default.
