Seasonal characteristics of subsoil salinity of coastal parks in Shanghai

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Vegetation in coastal parks is more sensitive and fragile to subsoil salinity. 600 subsoil samples in a newly-developed coastal park and 1800 subsoil samples in three old non-coastal parks in Shanghai, China were collected. The subsoil salinity of coastal park is 4.83 times higher than that of non-coastal parks. The average subsoil salinities in Spring and Winter are higher than that in Summer and Autumn. Collaborative vertical trend of subsoil salinity for four seasons is significant (p<0.05). Therefore, the ditches should be adjusted for salt elimination according to location of highly saline plaques, and seepage interception projects should be set up between green-space and unimproved land and the vegetation should be watered more frequently in Spring than that in other seasons.
