Research on the Ecological Strategies in Landscape Design and Planning Kezhen Sun College of Architecture and Urban Planning, Beijing University of Civil Engineering and Architecture，China Add.100044 No.1 Zhanlanguan road, West City District of Beijing, China sunkezhen@bucea.edu.cn Keywords: Landscape Design and Planning, Ecological environment, Landscape ecosystem, Sustainability, strategy, System theory Abstract This article argues the problem of ecological strategies in the landscape design and planning, and the main contents of ecological strategies.
The collaborative and interdisciplinary working According to the theory of landscape ecosystem, many projects such as historic preservation, ecological conservation, restoration ecology, soil and water conservation, and landscape architecture, environmental engineering and so on, are involved in landscape design and planning.
A major category can be classified as landscape architecture, urban planning and design, ecology and restoration ecology, biology and forestry, history and historic preservation, environmental engineering, soil and water conservation etc.
Some ecological knowledge should be collected and extracted from ecology and restoration ecology, biology and biotechnology, garden architecture and forestry, environmental engineering, soil and water conservation, history and historic preservation etc.
