Paper title:暖湿化背景下的高原降水变化对农业影响浅析——以青海省海西州都兰县为例
Paper abstract:气候变化深刻影响全球农业发展格局,特别是青藏高原的暖湿化改变了高原农民原本的耕作方式。因此,研究气候变化背景下降水的农业影响对进一步改进农业发展模式意义重大。本研究聚焦青海省海西州都兰县,运用回归分析揭示2000—2020年的降水变化,通过自相关分析定量反映降水的空间聚集情况,并采用Geodetecter模型探讨影响降水空间分异的因素,结果显示:(1)2000—2020年的都兰县降水量缓慢增长,但波动较大;(2)都兰县降水量具有一定空间聚集现象,但程度较小,其基本分布格局为南多北少、东多西少;(3)都兰县降水量的空间分布受大气温度与DEM影响最为显著,在大气温度低和高海拔的地区较为聚集。基于降水数据的分析结果,本研究根据都兰县农业发展现状,进一步探讨了降水变化对都兰县农业发展的影响,并给出了应对措施,为当地可持续发展提供科学参考。

Paper title:Shift regime of multiphase water in the Three-River-Source Region
Paper abstract:A significant hydrological feature of the cryosphere is that water bodies exist in multiphase forms. Abrupt shifts in multiphase water indicate a break in the stability of the hydrological cycle and may threaten sustainable water resource supply. However, the phenomenon of abrupt shifts in alpine regions and their underlying driving mechanisms remain poorly understood. This study investigated the spatiotemporal patterns, gradual accumulation–abrupt characteristics, and driving mechanisms of multiphase water in the Three-River-Source Region (TRSR). The results revealed that solid water decreased, while liquid and gaseous water increased from 2002 to 2022. A total of 32.25% of the TRSR experienced abrupt shifts, primarily in the Yangtze and Yellow River source regions. The critical thresholds for solid, liquid, and gaseous water were identified as 2.54×104 m3,1.60×107 m3, and 3.21×105 m3, respectively. Abrupt shifts were most likely to occur when the volumes of solid, liquid, and gaseous water reached their respective thresholds. Climate was the primary driver of gradual and abrupt changes, while vegetation significantly moderated solid water ablation and enhanced liquid water accumulation in regions with abrupt shifts. Specific environmental conditions, such as leaf area index (0.11–1.00), annual rainfall (199.26–649.76 mm), and the maximum temperature (0.83–9.80℃), were found to increase the likelihood of triggering abrupt shifts. This study proposed a more accurate method to depict the shift regime of multiphase water, providing critical insights for water resource management and risk governance in alpine regions.
