This article studies the intersection of systems ecology and urban planning in the Inter-Institutional Policy Simulator (IIPS) project, conducted between 1970 and 1974 in Metro Vancouver, and tries to understand how ecologists influenced the planning of urban systems. I analyze the rise and fall of IIPS as the interaction between “IIPS the Platform” and “IIPS the Product,” or between the network of experts and the simulator they aimed to create. Although IIPS failed to create a desirable product, I argue that the project can exemplify ecologists’ desire to reform the practice of urban planning through the power of systems science.

“系统”作为边界对象：机构间政策模拟器（IIPS）项目中的系统生态和城市规划，1970-1974年

本文研究了1970年至1974年在大温哥华地区进行的机构间政策模拟器（IIPS）项目中系统生态学与城市规划的交叉，并试图了解生态学家如何影响城市系统的规划。我将IIPS的兴衰分析为“平台的IIPS”和“产品的IIPS”之间，或专家网络与他们旨在创建的模拟器之间的相互作用。尽管IIPS未能创造出理想的产品，但我认为该项目可以体现生态学家通过系统科学的力量改革城市规划实践的愿望。
