英文摘要	In this work we analysis the relationship between the industrial structure and regional subsidence base on the research in past. We mapped the spatial and temporal patterns of the land subsidence near the city of Hangzhou, China by PSI analysis with more than 49 scenes of ERS-1/2 SAR images acquired from 1992 to 2006.[1] According to the PSI results, 13 subsidence centers (express by red dashed circle in fig 1) were found in the Xiaoshan (a district of Hangzhou, China) Economic and Technological Development Zone. Characteristics of each subsidence centers are different. I have found out 86 different enterprises belong to different industrial types (express by red pin tag in Fig 1) by field survey. The Zone was approved as a state-level development zone by the State Council in May, 1993. The structure of the Zone industry Includes 10 main types, Such as petrochemical, power industry, manufacturing and so on. Fig 2 shows the Percentage of different types of enterprises. The main reason of land subsidence in the Zone is groundwater exploitation, which is necessary for the rapid economic development.; Engineering, Electrical & Electronic; Geosciences, Multidisciplinary; Remote Sensing; EI; CPCI-S(ISTP); 0
