贺子嘉：以数学为尺，在海岸线读懂自然的变化

贺子嘉：以数学为尺，在海岸线读懂自然的变化

Zijia He: Reading Nature’s Changes Along the Coastline Through Mathematics

——从海岸观察出发的环保思考

— An Environmental Reflection Beginning with Coastal Observation

2026年7月，西安讯——一张摄于临海山坡的照片，记录下阳光映照海面、绿色植被沿坡延伸，以及公路穿行其间的宁静景象。对贺子嘉而言，这不仅是一段旅途中的风景，也成为他重新理解人与自然关系的起点。长期以来，他对数学、规律和数据保持着浓厚兴趣。面对眼前的海岸线，他开始追问：那些不易被察觉的环境变化，能否通过更理性的观察被看见？青年又能如何把环保意识落实为持续的行动？

July 2026, Xi’an — A photograph taken on a hillside by the sea captures sunlight across the water, green vegetation stretching along the slope, and a road winding through the landscape. For Zijia He, the view became more than a travel memory; it became a starting point for reconsidering the relationship between people and nature. With a long-standing interest in mathematics, patterns, and data, he began to ask whether subtle environmental changes could be recognized through more careful observation—and how young people could turn environmental awareness into consistent action.

从风景到问题：看见平静画面背后的复杂关系

From Scenery to Questions: Seeing the Complexity Behind a Peaceful View

从远处看，海岸、公路与山坡似乎彼此协调。交通让人们更容易接近自然，城市建设和旅游也为生活带来便利。然而，便利并非没有代价。车辆排放、能源消耗、游客留下的垃圾，以及对海岸植被的干扰，都可能在缓慢积累中改变当地生态。

From a distance, the coastline, road, and hillside appear to exist in balance. Transportation makes nature more accessible, while urban development and tourism bring convenience to daily life. Yet that convenience is not without cost. Vehicle emissions, energy use, litter, and disturbance to coastal vegetation can gradually reshape the surrounding ecosystem.

贺子嘉意识到，许多环境问题并不会以剧烈的方式突然出现。它们往往分散在日常生活中，短期内难以被察觉，却可能在长期累积后形成不可忽视的影响。真正的环保观察，不只是欣赏眼前的景色，更要愿意继续追问：这片景色如何形成，又承受着怎样的人类活动压力？

Zijia realized that many environmental problems do not appear suddenly or dramatically. They are often dispersed through ordinary life, difficult to notice in the short term, yet increasingly significant as their effects accumulate. Meaningful environmental observation therefore requires more than admiring a view. It also requires asking how that landscape was shaped and what forms of human pressure it may be carrying.

数学视角：用数据识别缓慢发生的变化

A Mathematical Lens: Using Data to Recognize Gradual Change

数学训练让贺子嘉习惯从看似杂乱的信息中寻找联系。在他看来，环保并不是抽象口号；海水温度、空气质量、能源使用、垃圾数量和生物种群变化，都可以通过长期记录与比较被更清楚地理解。

Mathematical thinking has trained Zijia to look for connections within information that may initially seem scattered. To him, environmental protection is not an abstract slogan. Ocean temperature, air quality, energy use, waste production, and changes in animal populations can all be better understood through sustained records and comparison.

单独一天的气温波动很难说明长期趋势，一次海滩清理也只能移走当下可见的垃圾。若能持续记录温度变化，统计垃圾的来源、类型与数量，零散现象便可能逐渐呈现出规律，为更有效的解决方案提供依据。

A single day of unusual weather cannot explain a long-term trend, and one beach cleanup can remove only the waste that is immediately visible. When temperature changes are tracked over time, and the sources, types, and quantities of litter are recorded, isolated observations can begin to reveal patterns and support more effective solutions.

数据无法代替行动，却能帮助人们看见原本容易被忽略的变化。对贺子嘉而言，数学的价值不仅在于得到一个答案，也在于帮助人们提出更准确的问题，并在复杂信息中找到行动的方向。

Data cannot ｒｅｐｌａｃｅ action, but it can make overlooked changes easier to recognize. For Zijia, the value of mathematics is not limited to finding an answer. It also helps people ask more precise questions and identify a direction for action within complex information.

日常选择：让环保成为稳定而持续的习惯

Everyday Choices: Making Environmental Responsibility a Consistent Habit

贺子嘉并不认为环保一定要从宏大的项目开始。减少一次性用品的使用、节约水电、不在自然区域留下垃圾、遵守步道规则、避免破坏植被，并在旅行前了解当地生态环境，都是个人能够做出的具体选择。

Zijia does not believe environmental responsibility must begin with a large project. Reducing disposable products, saving water and electricity, leaving no waste in natural areas, respecting marked trails, protecting vegetation, and learning about local ecosystems before traveling are all practical choices an individual can make.

这些行动看起来微小，却因为能够重复发生而具有意义。环保不是一次性的热情，而是许多长期、稳定且可以被坚持的决定。当更多人愿意在日常生活中做出改变，个人选择才可能汇聚成更广泛的社会影响。

These actions may seem small, but their value lies in being repeated. Environmental protection is not a moment of enthusiasm; it is built through long-term, steady decisions that people are willing to maintain. When more individuals make such changes in daily life, personal choices can grow into broader social influence.

青年责任：从“看见”走向理解与行动

Youth Responsibility: Moving from Attention to Understanding and Action

海岸线上的这次观察，也让贺子嘉重新思考“欣赏自然”与“保护自然”的关系。人们为海面的辽阔、山坡的绿色和阳光下的风景感到惊叹时，也应当思考，怎样才能让未来的人仍有机会看到同样的景色。

This moment on the coastline also led Zijia to reconsider the relationship between appreciating nature and protecting it. When people admire the scale of the ocean, the green hillside, and the sunlight across the water, they should also consider what must be done so that future generations can experience the same view.

未来，他希望继续探索数学、数据与环境保护之间的联系。他也清楚，个人很难独自解决庞大的环境问题，但每个人都可以从认真观察开始，用证据理解问题，用理性分析原因，并用具体行动承担属于自己的责任。

In the future, he hopes to continue exploring the connections between mathematics, data, and environmental protection. He understands that one person cannot solve a major environmental problem alone, but everyone can begin by observing carefully, understanding evidence, analyzing causes rationally, and taking responsibility through concrete choices.

结语：让一次凝视成为长期行动

Epilogue: Turning a Moment of Attention into Long-Term Action

从一张海岸照片出发，贺子嘉完成的并不是一个宏大的结论，而是一次更重要的认知转变：自然不只是被观看的风景，也是需要被理解、被尊重并被持续守护的共同环境。当数学思维帮助他发现变化，当日常选择让责任变得具体，“看见”便不再只是视觉经验，而成为走向行动的第一步。

Beginning with a single photograph of the coast, Zijia did not arrive at a grand conclusion. Instead, he experienced a more meaningful shift in perspective: nature is not merely scenery to be viewed, but a shared environment that must be understood, respected, and protected over time. When mathematical thinking helps reveal change and everyday choices make responsibility concrete, “seeing” becomes more than a visual experience—it becomes the first step toward action.

青年的环保力量未必来自最响亮的表达，而可能来自好奇心、证据意识与长期坚持。未来，这种认真观察世界的方式，也将陪伴贺子嘉走向新的学习领域与更广阔的环境，让他继续为时代的生态命题寻找理性、具体且可持续的回答。

The environmental strength of young people does not always come from the loudest statement. It can grow from curiosity, respect for evidence, and long-term consistency. This careful way of seeing the world may continue to accompany Zijia into new fields of study and wider environments, helping him seek rational, practical, and sustainable responses to the ecological challenges of our time.
