Abstract: Under China's fast urbanization and industrial upgrading process，a large number of traditional industrial enterprises are undergoing relocation，reform，or bankruptcy． As a result，the number of industrial brownfield sites have increased greatly in recent years． Spatially，the topography of this type of brownfield is generally level，with large-scale industrial heritage buildings and structures acting as dominant spatial elements on site． Contamination mainly exists in soil and underground water body，hard to detect and has a long incubation period． Industrial brownfield regeneration projects normally have a long timeframe with uncertainty during the process． The well-known Gas Works Park in Seattle，USA，can serve as an exemplar of these characteristics． It has experienced several rounds of environmental investigation and remediation process，lasting more than half century． However，until today，there might still be contamination remaining on site
