| 摘 要： | 利用1958～2003年黑龙江省均匀分布的16站月降水和平均气温资料,通过计算地表最大潜在蒸发、地表干燥度指数、地表水分盈亏量,对比分析了黑龙江省各不同干湿气候区域地表干湿状况的分布规律及其变化趋势,并讨论了它与降水和气温的关系。给出了地表干燥度指数的地理分布和变化趋势。研究表明:全省及各区地表干燥度均存在变干的趋势,特别在进入21世纪以后,变干的趋势更加明显。但各地变干的特征差别较大,其中西部地区地表变干的程度最为严重,北部地区最轻,甚至个别地区还有变湿的倾向。

| Abstract: | Using the monthly precipitation and average temperature data of 16 meteorological stations in the period 1958-2003 over HeiLongJiang province,we calculated the latent maximum evaporation and drying power as well as profit and loss of soil moisture of earth's surface.According to constantly analyzing the transformation trends and distribution features of the earth's surface conditions in varying climate zones,we discovered the relationship between the features and the precipitation & temperature.The trend of drying has shown over all HeiLongJaing province,but the drying speed was different. |
