Reusable: Design shall ensure that all resource within the site are at its utmost reuse rate. In this project, the design team reuses the existing surface soil and excavated soil to shape the landform.
Effective: Given reusable principle, design shall apply latest technology when necessary to achieve higher efficiency and effectiveness than grey infrastructure does and ensure the continuity in ecology. Qingdao airport has designed a rainwater collection and purification system which well-integrated with landform, it will also be used as a detention area and flood drain channel during storm.
3. Cultural（文化印记）：景观基础设施设计应融入地域文化，创造富有地域特色景观。如青岛机场的景观地形的塑造用融入最古老的” 齐 “字，并用波浪的形式阐释了地域文化特色。
Cultural: Design must take local cultural element into consideration and create a place with unique local feature. The cultural element in our project is expressed through modifying the shape of the ancient Chinese Character “QI” from two dimension to three dimension, and arranging such modification in a way that a series of wave form can be perceived, which brings additional marine cultural experience in Qingdao.
4. Operational（便于管理）： 景观基础设施设计应提前考虑未来智能化的维护管理需求。 并结合灰色基础设施的维护管理要求统一设计。如青岛机场的植物设计以开敞的缓坡及块面组团种植为主，便于未来智能化的维护。智能灌溉的使用也将有效降低人力成本和灌溉用水量。
Operational: Design shall consider future AI maintenance and management needs as well as requirements of grey infrastructure. For example, spacious and gentle ramps are designed for the airport. It will provide convenience for future intelligent maintenance, for example intelligent irrigation. Such technology will also reduce labor costs and water consumption effectively.
5. Diversified（复合功能）：景观基础设施设计应赋予灰色基础设施新的社会经济功能，将灰色基础设施转变成综合性的公共景观，促进人与场地的互动。 如青岛机场的中央花园地块，用景观空间处理手法统筹复杂的地上地下设施，预留了给排水和公共设施的接口，便于举办各种社交活动。
Diversified: Social, economic function shall be endowed by design to grey infrastructure, to transform grey infrastructure into multi-functional public landscape, and to encourage people interact with the space. The central garden is designed to transform the chaotic space into a new social hub, where people can interact and communicate with the site. The garden also provides utility service such water supply, plugs and other facilities to public to encourage various social activities.
6. Economic（经济实用）：景观基础设施设计应注重与基础设施工程的合并，减少重复建设投资。 如青岛机场的景观水系统与市政管网融为一体，取代了部分传统管网，让自然做功，节省了管网系统的投资和维护成本。
Economic: Design shall fully merge landscape engineering with the different types of infrastructure, to minimize overlapping in investment and construction. Traditional concrete pipe network is replaced by new water collection and purification system, saving the investment and maintenance costs.
