摘要
结合辽宁省水资源状况,对全省划分西部、中北部、东南部三个区域,以1956—1979年、1980—2000年、2001—2011年三个时间段为基础,分析对比全省及分区多年平均降水量、地表水资源量、水资源总量;利用全省1956—2011年降水量、地表水资源量时间序列资料,采用10a滑动平均法与线性趋势分析法,分析全省及分区水资源量变化趋势。
Combined with the situation of water resources in Liaoning Province, divided into the three regions of western, central and southeast and southeastern, based on the period of 1956--1979, 1980-- 2000, 2001--2011, analyzed the province and the partition compared to the average annual precipitation, surface water resources, water resources. Based on the time series data of precipitation and surface water resources from 1956 to 2011, the province and the division of water resources trends was analyzed by the 10-year moving average method and the linear trend analysis method.
