Evaluating rainwater storage capacity of green infrastructure for urban flood management
Green infrastructure (GI) distribution from 1995 to 2018 was interpreted based on Normalized Differential Vegetation Index threshold method. According to the leaf area index and soil bulk density, the canopy storage capacity and soil storage capacity of GI were calculated, and the total rainwater storage capacity of GI in different years in Shenyang was evaluated. The area of GI shows a trend of decreasing from 1995 to 2010 and then gradually increased till 2018. GI in the first ring and the second ring area was gradually increasing from 1995 to 2018. GI with high canopy storage capacity area is mainly distributed in the north of the second ring area and the third ring area. The rainwater storage capacity of Shenyang in 2018 is 110.8 mm, including 7.5 mm canopy storage capacity and 103.3 mm soil storage capacity. Low rainwater storage capacity (<25.5 mm) is more likely to lead to urban waterlogging.
