**中新社北京5月15日电 (记者 陈杭)** 随着气温的逐渐升高，北京市气象局于5月15日宣布，今年北京的入夏日期为5月7日。这一日期相比常年（1991-2020年平均）的入夏日期偏早了13天。
入夏时间的提前，反映出中国首都气候变化的一个趋势。近年来，全球气候变暖的影响日益显著，中国也不例外。北京作为中国的首都，气候变化对其居民的生活、城市的规划管理以及农业等各个领域都可能产生深远影响。
气象专家指出，气候变暖导致气温升高，是入夏时间提前的主要原因。这不仅意味着北京将面临更频繁的高温天气，也可能增加城市热岛效应，对城市生态环境和居民健康带来挑战。
对于农业生产而言，入夏时间的提前可能带来双重影响。一方面，早熟作物的种植时间可以提前，可能增加一季度的产量；另一方面，如果高温天气持续时间长，可能会对农作物的生长造成不利影响，特别是对晚熟作物的成熟和品质可能带来负面影响。
此外，气候变化对水资源的影响也不容忽视。入夏时间提前可能导致蒸发量增加，进一步加剧水资源紧张状况。这要求北京市和相关管理部门在水资源管理上做出更为科学的规划和调配，确保城市水资源的合理利用和供应安全。
北京市气象局表示，将继续密切关注气候变化趋势，加强气象监测和预测工作，为政府和公众提供及时、准确的气象服务，帮助市民做好应对气候变化的准备。
在全球气候变化的大背景下，中国持续加强生态文明建设，积极推动绿色低碳发展，努力实现人与自然和谐共生。北京作为国家的政治、文化和国际交流中心，在应对气候变化方面也承担着重要责任。未来，北京市将继续采取有效措施，促进城市可持续发展，提高市民的绿色福祉。

### Beijing’s Summer Arrives on May 7th, 13 Days Early Than Usual
**BEIJING, May 15, Xinhua News Agency (Reporter Chen Hang)** — As temperatures gradually rise, the Beijing Meteorological Bureau announced on May 15th that this year’s official start of summer in Beijing was on May 7th. This date is 13 days earlier than the average date of summer onset based on the period from 1991 to 2020.
The early arrival of summer reflects a trend of climate change in the Chinese capital. In recent years, the impact of global warming has become increasingly significant, and China is not immune to this phenomenon. As the capital of China, Beijing is experiencing climate change that could have profound effects on the lives of its residents, urban planning and management, and agriculture, among other sectors.
Meteorological experts pointed out that the rise in temperature due to climate warming is the primary cause for the early onset of summer. This not only means that Beijing may face more frequent spells of high temperatures but could also intensify the urban heat island effect, posing challenges to the urban ecosystem and public health.
For agricultural production, the early arrival of summer may have both positive and negative impacts. On one hand, the planting time for early-maturing crops can be advanced, potentially increasing the yield in the first quarter. On the other hand, if high temperatures persist for a long time, it could adversely affect crop growth, particularly the maturation and quality of late-maturing crops.
Moreover, the impact of climate change on water resources should not be overlooked. The early arrival of summer could lead to increased evaporation, further exacerbating the water shortage. This necessitates more scientific planning and allocation of water resources by the Beijing Meteorological Bureau and related management departments to ensure the rational use and supply security of the city’s water resources.
The Beijing Meteorological Bureau stated that it will continue to closely monitor climate change trends, strengthen meteorological monitoring and forecasting, and provide the government and the public with timely and accurate meteorological services, helping citizens prepare for climate change.
Under the backdrop of global climate change, China continues to strengthen ecological civilization construction and actively promote green and low-carbon development, striving to achieve harmonious coexistence between humans and nature. As the political, cultural, and international exchange center of the country, Beijing bears significant responsibilities in addressing climate change. In the future, Beijing will continue to take effective measures to promote sustainable urban development and enhance the green well-being of its citizens.
