近年來，隨著城市化進程的加速，人們對於庭園景觀工程的需求也越來越高。在這個過程中，許多最新技術被應用於庭園景觀設計中，其中包括電磁閥、過濾器、自動灌溉、雨水回收等關鍵技術。
電磁閥是一種控制水流的裝置，可以根據預設的程序自動開啟或關閉水源，實現自動灌溉系統的運作。過濾器則可以過濾水中的雜質，確保灌溉水質的純淨。而自動灌溉系統不僅可以節省人力成本，還可以確保植物得到適量的水分，提高庭園景觀的維護效率。
另外，雨水回收系統也是一個重要的技術，可以將雨水收集起來再利用於庭園灌溉中，實現節水環保的效果。這些技術的應用不僅提高了庭園景觀工程的效率和品質，也符合現代社會對環保和可持續發展的要求。
在公用事業設施工程中，這些技術也被廣泛應用，例如在城市公園、廣場等公共場所的庭園景觀設計中。通過運用電磁閥、過濾器、自動灌溉等現代化技術，可以打造出更加美觀、節能環保的庭園景觀，為城市居民提供更好的休閒空間。

Title: Key Technologies for Modern Garden Landscape Engineering
Article: In recent years, with the acceleration of urbanization, the demand for garden landscape engineering has been increasing. In this process, many latest technologies are applied in garden landscape design, including key technologies such as electric valves, filters, automatic irrigation, and rainwater harvesting.
The electric valve is a device that controls water flow and can automatically open or close the water source according to a preset program, realizing the operation of an automatic irrigation system. The filter can filter out impurities in the water, ensuring the purity of irrigation water. The automatic irrigation system not only saves labor costs but also ensures that plants receive the right amount of water, improving the maintenance efficiency of garden landscapes.
Furthermore, rainwater harvesting system is also an important technology that collects rainwater for reuse in garden irrigation, achieving water-saving and environmental protection effects. The application of these technologies not only improves the efficiency and quality of garden landscape engineering but also meets the requirements of modern society for environmental protection and sustainable development.
In public utility facilities engineering, these technologies are widely used in garden landscape design in public places such as city parks and squares. By using modern technologies such as electric valves, filters, automatic irrigation, we can create more beautiful, energy-saving, and environmentally friendly garden landscapes, providing better leisure spaces for urban residents.
