摘要
选取衡水市2017—2021年15个土壤墒情监测站点的原始资料,结合同期的降水数据,计算5年内土壤含水率的年平均值,发现降水量是影响年际土壤含水率变化的主要因素;计算出5年内相同监测时间的土壤含水率平均值、5年内月平均土壤含水率,发现年内土壤含水率变化与降水量变化基本一致;将衡水市分为东北部、中部、西南部三个区域,计算各区域每个县(市、区)的月平均土壤含水率,并与衡水市多年月平均土壤含水率对比,发现东北部土壤含水率高于西南部,中部土壤含水率居中。分析衡水市土壤墒情变化规律,有利于指导农业生产、合理利用水资源等工作。
Based on the original data of 15 soil moisture monitoring stations in Hengshui from 2017 to 2021,combined with the precipitation data of the same period,the annual average value of soil moisture content in five years is calculated.It is found that precipitation is the main factor affecting the annual change of soil moisture content.The average soil moisture content in the same monitoring time in 5 years and the monthly average soil moisture content in 5 years are calculated.It is found that the change of soil moisture content is basically consistent with the change of precipitation in the year.Hengshui City is divided into three regions:the northeast,the central part and the southwest.The monthly average soil moisture content of each county(city,district)is calculated,and compared with the average monthly soil moisture content of Hengshui City in many years.It is found that the soil moisture content in the northeast is higher than that in the southwest,and the soil moisture content in the central part is in the middle.The analysis of the law of soil moisture change in Hengshui City is conducive to guiding agricultural production and rational use of water resources.
