与此同时,第二次青藏科考评估结果还表明,尽管"亚洲水塔"未来水量趋于增加,但由于南亚、中亚大 部分国家人口的快速增加,上游供水量增加并不能满足其快速增长的用水需求。因此,未来"亚洲水 塔"下游的水资源要进行区域性分策应对和国际性综合协调,要强化冰崩、冰湖溃决等灾害科学预警体 系的构建,分享中国水资源管理的成功经验,实施更加有效的水资源可持续管理措施,构建"亚洲水 塔"水资源命运共同体。(记者李华 李键) 新华社拉萨11月19日电 第二次青藏科考研究发现,有"亚洲水塔"之称的青藏高原供水能力显著增强, 预估本世纪末外流区径流量增幅最高可达49%。 19日在拉萨举行的第二次青藏科考成果综合集成应用发布会上,中国科学院院士、第二次青藏科考队队 长姚檀栋介绍了这一研究成果。姚檀栋说,气候暖湿化导致"亚洲水塔"失衡,表现为冰川、积雪等固态 水体快速减少与湖泊、河流等液态水体广泛增加的固液相态失衡,过去40年长江源、澜沧江源等主要流 域径流持续增加,预估本世纪末外流区径流量增幅最高可达49%。 ...

Group 1: Climate Change Impact on Agriculture - The increasing frequency of high temperatures and heavy rainfall is forcing agricultural practitioners to adopt more proactive measures to mitigate challenges [18][19] - High temperatures above 35°C can lead to adverse effects on apple trees, including color changes and deformation, while excessive rainfall can cause root rot and other diseases [19] - Farmers are now closely monitoring weather forecasts to prepare for extreme weather conditions, ensuring timely application of fertilizers and pesticides to protect crops [19] Group 2: Impact on Cultural Heritage Preservation - The increase in rainfall poses significant threats to ancient buildings, particularly wooden structures, which are susceptible to decay in humid conditions [20][21] - The preservation of cultural relics requires continuous environmental monitoring, which is often lacking for lower-tier heritage sites, making them vulnerable to extreme weather [20] - Changes in temperature and humidity directly affect the integrity of murals and wall paintings, leading to deterioration and loss of cultural heritage [21][22] Group 3: Broader Implications for Industries - The shift towards a "warm and humid" climate in northern regions is expected to affect various industries, necessitating adaptations to new weather patterns [22][23] - The changing climate will have direct and indirect impacts on every sector and individual, highlighting the need for comprehensive strategies to address these challenges [22][23]
