| 摘 要： | 利用新疆伊犁河流域1961-2007年历年逐月气温、降水资料,运用迈阿密模型、桑斯维特纪念模型计算新疆伊犁河流域近50年的牧草气候生产潜力。结果表明,流域气候生产潜力为4083.75~8415.42kg/(hm2·a),潜力较大,不同气候区有所差异。平原区气候生产潜力较小,且稳定性较差,丘陵区和山间盆地区气候生产潜力较大,山间盆地区同时也具有较好的稳定性。与气温相比,降水量是限制流域牧草气候生产潜力的主导因素。近50年来,气候生产潜力变化较大,总体呈上升趋势,尤其是2000年以来,增加幅度变大。

| Abstract: | Based on precipitation and temperature data between 1961 and 2007, the production potential of grassland climate in the Ili River Basin was calculated by the Miami and Matharnthwaite Memorial models. The grassland climate in the Ili River Basin showed the highest production potential with 4 083.75-8 415.42 kg/(ha·a). The production potential was different in different climatic regions. The plains areas showed the lowest production potential with instability while the hilly regions and mountain basin areas showed relatively high production potential with good stability in mountain basin areas. Precipitation was a more dominant factor than temperature for production potential of grassland climate in the Ili River Basin. In general, the production potential of grassland climate in the Ili River Basin showed an increasing trend, especially after 2000. |
