Mr Xu 许先生
I am a postdoctoral fellow at Wuhan University, currently working at the University of Hong Kong. Before coming to HKU, I worked in Wuhan for a period of time. My research field is geography, specifically urban geography. I mainly analyze the distribution and development of cities in space, which is a very interesting and important research direction.
In my research, we use a lot of advanced technologies. For example, we use remote sensing technology, mainly satellite images. This allows us to observe the entire city from a high altitude and see its changes. We also use geographic information systems, a powerful tool that can help us integrate and analyze various geographic data.
Our workflow is usually like this: we collect satellite images from different time points, possibly from a few years ago or even decades ago. Then we carefully analyze these images to see how the city has expanded in space. This allows us to track the development of the city and understand how it has changed over time.
At the University of Hong Kong, I am doing postdoctoral research in the School of Architecture. This might sound a bit strange—a geographer working in the School of Architecture. But in fact, urban geography and architecture have many intersections. Here, I continue to study what I did at Wuhan University, but with new perspectives and methods.
As a global scientist, my research involves many aspects. I am particularly interested in brownfields. Brownfields are lands that were once used for industrial or commercial purposes but may now be polluted and abandoned. This is a very important topic in urban planning and sustainable development. How to reuse these lands and how to carry out environmental remediation are questions we need to think about.
Each city has its unique challenges and opportunities. Beijing and Hong Kong are two good examples; their urban structures and development patterns are very different. My job is to study these different urban patterns, understand how they were formed, and how they change over time.
Overall, my research aims to understand how cities develop and how to better plan our urban spaces. This involves not only geography but also environmental science, sociology, and many other disciplines. We need to consider many factors, such as population distribution, economic activities, transportation networks, green space planning, and so on.
Our ultimate goal is to create more livable and sustainable urban environments. This means that we need to pay attention not only to the physical structure of the city but also to the quality of life of its residents. We hope that our research can provide valuable references for urban planners and policymakers, helping them make better decisions.
This work is full of challenges but also very meaningful. Every time I see a city become better because of good planning, I feel very gratified. This is why I love my job and why I choose to continue to work in this field.
我是武汉大学的博士后，现在在香港大学工作。在来港大之前，我在武汉工作了一段时间。我的研究领域是地理学，具体来说是城市地理学。我主要分析城市在空间中的分布和发展，这是一个非常有趣且重要的研究方向。
在我的研究中，我们使用了很多先进的技术。比如说，我们使用遥感技术，主要是卫星图像。这让我们能够从高空俯视整个城市，观察它的变化。我们还使用地理信息系统，这是一个强大的工具，可以帮助我们整合和分析各种地理数据。
我们的工作流程通常是这样的：我们收集不同时间点的卫星图像，可能是几年前的，也可能是几十年前的。然后我们仔细分析这些图像，观察城市是如何在空间中扩展的。这让我们能够追踪城市的发展历程，了解它是如何随时间变化的。
在香港大学，我在建筑学院做博士后。这可能听起来有点奇怪，一个地理学家在建筑学院工作。但实际上，城市地理学和建筑学有很多交叉点。我在这里继续研究我在武汉大学时所做的工作，但也有了新的视角和方法。
作为一个全球科学家，我的研究涉及很多方面。我特别对棕地感兴趣。棕地是指那些曾经被用于工业或商业用途，但现在可能被污染和废弃的土地。这在城市规划和可持续发展中是一个非常重要的话题。如何重新利用这些土地，如何进行环境修复，这些都是我们需要思考的问题。
每个城市都有其独特的挑战和机遇。北京和香港就是两个很好的例子，它们的城市结构和发展模式有很大的不同。我的工作就是研究这些不同的城市模式，了解它们是如何形成的，又是如何随时间变化的。
总的来说，我的研究旨在理解城市如何发展，如何更好地规划我们的城市空间。这不仅涉及到地理学，还包括环境科学、社会学等多个学科。我们需要考虑的因素很多，比如人口分布、经济活动、交通网络、绿地规划等等。
我们的最终目标是创造更宜居、更可持续的城市环境。这意味着我们不仅要关注城市的物理结构，还要考虑到居民的生活质量。我们希望通过我们的研究，能为城市规划者和政策制定者提供有价值的参考，帮助他们做出更好的决策。
这个工作充满挑战，但也非常有意义。每当我看到一个城市因为好的规划而变得更美好，我就感到非常欣慰。这就是为什么我热爱我的工作，也是为什么我选择继续在这个领域深耕。
我係武漢大學嘅博士後，而家喺香港大學工作。喺嚟港大之前，我喺武漢做咗一段時間。我嘅研究領域係地理學，具體嚟講係城市地理學。我主要分析城市喺空間中嘅分佈同發展，呢個係一個好有趣又重要嘅研究方向。
喺我嘅研究中，我哋用咗好多先進嘅技術。譬如話，我哋用遙感技術，主要係衛星圖像。呢個畀我哋可以從高空俯視成個城市，觀察佢嘅變化。我哋仲用地理信息系統，呢個係一個好強大嘅工具，可以幫我哋整合同分析各種地理數據。
我哋嘅工作流程通常係咁樣嘅：我哋收集唔同時間點嘅衛星圖像，可能係幾年前嘅，都可能係幾十年前嘅。然後我哋仔細分析呢啲圖像，觀察城市係點樣喺空間中擴展嘅。呢個畀我哋可以追蹤城市嘅發展歷程，了解佢係點樣隨住時間變化嘅。
喺香港大學，我喺建築學院做博士後。呢個可能聽起嚟有啲奇怪，一個地理學家喺建築學院工作。但實際上，城市地理學同建築學有好多交叉點。我喺呢度繼續研究我喺武漢大學時所做嘅嘢，但都有咗新嘅視角同方法。
作為一個全球科學家，我嘅研究涉及好多方面。我特別對棕地感興趣。棕地係指嗰啲曾經被用作工業或商業用途，但而家可能被污染同廢棄嘅土地。呢個喺城市規劃同可持續發展中係一個好重要嘅話題。點樣重新利用呢啲土地，點樣進行環境修復，呢啲都係我哋需要思考嘅問題。
每個城市都有佢獨特嘅挑戰同機遇。北京同香港就係兩個好好嘅例子，佢哋嘅城市結構同發展模式有好大嘅唔同。我嘅工作就係研究呢啲唔同嘅城市模式，了解佢哋係點樣形成嘅，又係點樣隨住時間變化嘅。
總嘅嚟講，我嘅研究旨在理解城市點樣發展，點樣更好咁規劃我哋嘅城市空間。呢個唔單止涉及到地理學，仲包括環境科學、社會學等多個學科。我哋需要考慮嘅因素好多，譬如人口分佈、經濟活動、交通網絡、綠地規劃等等。
我哋嘅最終目標係創造更宜居、更可持續嘅城市環境。呢個意味住我哋唔單止要關注城市嘅物理結構，仲要考慮到居民嘅生活質素。我哋希望通過我哋嘅研究，可以為城市規劃者同政策制定者提供有價值嘅參考，幫助佢哋做出更好嘅決定。
呢個工作充滿挑戰，但都好有意義。每當我見到一個城市因為好嘅規劃而變得更加靚，我就感到好欣慰。呢個就係點解我鍾意我嘅工作，都係點解我選擇繼續喺呢個領域深耕。
