近50年黑龙江省水分盈亏状况变化特征研究
Variation Characteristics of Water Budget Condition of Heilongjiang Province in Recent 50 Years
摘要
Abstract
Based on the 1961 -2010 weather data from 65 meteorological stations in Heilongjiang Province, using the statistic software and GIS, the change characteristics of water budget, including the precipitation, reference evapotranspiration and water budget in the whole year and the temperature-defined growing season, were analyzed. As indicated by the results, during the whole year and the temperature-defined growing season from 1961 to 2010, the precipitation decreased, the annual reference evapotranspiration decreased, but the reference evapotranspiration during the temperature-defined growing season presented an increasing trend. Hie water resources were generally characterized by water deficit, especially after 21st century.关键词
