An intervention approach framework for landscape architecture to promote public participation in the response to climate change was proposed based on the three process dimensions of “cognition-emotion-behavior” of public participation and the theory of planned behavior to enhance the key role of landscape architecture in promoting public participation in the response to climate change.Three levels including willingness to enhance， action to stimulate， and long-term investment were covered.Seven key measures for intervention were included.In terms of enhancing awareness， the climate change information should be integrated into a multi-sensory public space design and activity system， and the spatial elements should be used to simulate possible local climate change impacts， in order to create climate change cognition and establish emotional links.In terms of stimulating action， pop-up experiences should be created and participatory low-carbon should be established.In terms of long-term guarantee mechanism， policy guarantees for public participation in the response to climate change should be promoted.The self-organization platforms in community should be built.The funding sources should be expanded.The feedback mechanisms for response actions should be improved.The sustainable public participation should be encouraged.Finally， three specific suggestions that China needs to focus on promoting public participation in the response to climate in the future were put forward based on the national conditions in China.Mainly including： changing traditional slogan promotion methods in the stage of increasing willingness， and integrating more climate change information into planning and design.Prioritize low-cost participatory low-carbon activities during the action phase to promote public participation.In the long-term investment stage， under the guidance of the government， expand funds and build self-organizing platforms， and develop sustainable evaluation feedback.
