在总结气候变化对流域水资源影响研究方法的基础上,分别构建了长江流域水量平衡简化模型和汉江流域9 km ×9 km的VIC分布式水文模型,并利用GCMs的输出驱动所建水文模型,预测了长江和汉江流域水资源在气候变化背景下的变化趋势。研究结果表明,对于长江和汉江流域,尽管未来气温序列预测值有所差异,但气温升高的趋势是一致的,未来降水的变化相对气温而言更复杂,趋势性不明显。基于气候模式预测信息估算的未来100 a流域水资源量变化情况基本为,前40 a左右呈逐渐减小,之后总体呈逐渐增大的趋势。
在總結氣候變化對流域水資源影響研究方法的基礎上,分彆構建瞭長江流域水量平衡簡化模型和漢江流域9 km ×9 km的VIC分佈式水文模型,併利用GCMs的輸齣驅動所建水文模型,預測瞭長江和漢江流域水資源在氣候變化揹景下的變化趨勢。研究結果錶明,對于長江和漢江流域,儘管未來氣溫序列預測值有所差異,但氣溫升高的趨勢是一緻的,未來降水的變化相對氣溫而言更複雜,趨勢性不明顯。基于氣候模式預測信息估算的未來100 a流域水資源量變化情況基本為,前40 a左右呈逐漸減小,之後總體呈逐漸增大的趨勢。

Based on summary of research approaches for the influence of climate change on water resources, a simplified water balance model for Yangtze River Basin and a 9km × 9km VIC distribution hydrological model for Hanjiang River Basin are estab-lished and by using the hydrology model established by GCMs driving output, the water resources variation tendencies of Yangtze River and Hanjiang River under the climate change are predicted. The research results show that for Yangtze River and Hanjiang River, although the predicted values of atmospheric temperature are not same, the rising tendency of atmospheric temperature are the same;the precipitation variation in future is more complicated compared with atmospheric temperature and the variation tend-ency is not obvious;the basin water resources in the next 100 years estimated by prediction information of climate model basically will decrease in the first 40 years and then gradually increase.
