中文摘要	利用美国NCAR中尺度非静力平衡模式MM5V36模拟分析了三江源区草地荒漠化对局地气候的影响.模拟结果表明:草地荒漠化后,源区地表温度白天升高晚上降低,昼夜温差增大;空气湿度减小;感热通量增加,潜热通量减小;边界层高度白天增加晚上减小,昼夜差增大,边界层内能量损失增加.综合分析说明草地荒漠化后源区气候变的更加干燥,不利于植被生长和水土保持,环境变的更加恶劣.
英文摘要	Using the US NACAR nonhydrostatic mesoscale model MM5V36 simulate the impact of the grassland desertification on local climate. The simulant results showed that after grassland desertification the grand temperature increased in the day time and decreased at night in source regions, the different temperature of day and night increased. The air moisture decreased. The sensitive heat flux increased and the latent heat flux decreased. The planet boundary layer height increased in the day time and decreased at night, the different height of day and night increased, the energy in planet boundary layer lost more. The analyzed results showed that the climate became drier after grassland desertification, it was not used for vegetation growing and water and soil holding. The environment became worse.
