Three data stacks including 11 X-band TerraSAR-X, 20 L-band ALOS PALSAR, and 35 C-band ENVISAT ASAR images were used to retrieve time series deformation from 2007 to 2010 in the LNC. In this work, we study the spatio-temporal evolution pattern of Linggang New City (LNC) in Shanghai, China, using space-borne synthetic aperture radar interferometry (InSAR) methods. However, the pattern of temporal evolution in reclamation settlements has rarely been analyzed. Also, the loss of ecosystem service value caused by reclamation was mainly due to the effects on food production, cultural use and waste disposal.Large-scale reclamation projects during the past decades have been recognized as one of the driving factors behind land subsidence in coastal areas. The loss of cultural service value was the smallest, accounting for 8.53%. Furthermore, the third place corresponded to the devaluation of the regulatory function value, which was 16.64%. The reduction in the value of cultural services, accounted for 23.07%. In addition, it was found that the loss of production service value was the largest, accounting for 51.76% of the total loss value. The results showed that the total value loss of marine ecosystem services was 30.95 × 10 4 yuan / hm 2 The index system was used to monetarily assess the damage caused by reclamation activities to ecosystem services in the coastal zone in Tianjin. The evaluation used the market value method, the alternative cost method, the investigation and evaluation method, and the result reference method.
For this purpose, the classification system of the Millennium Ecosystem Assessment was used to analyze the characteristics of the Tianjin's coastal ecosystem, and a unique index system was created to evaluate the service function. In order to quantitatively evaluate the loss of ecosystem service value in coastal zones due to reclamation, the present research selected Tianjin, a typical city with growing urbanization and industrialization in a China's coastal zone. However, it also causes important ecological problems, including affectations to ecosystem services. Reclamation is a strategy that alleviates land supply demand in coastal areas.
