Construction and Application of SOTER-LUCC Database in Fujian Province

Soil and terrain digital database (SOTER) recognizes the regional land according to terrain, rock, and soil providing a comprehensive framework for the data storage and retrieval. Currently SOTER has been authorized and become one of hotspots in the studies of soil and sustainable use of land. Combining SOTER and LUCC, taking SOTER units as the frame of LUCC information, constructing SOTER-LUCC database will provide more abundant and reliable data sources and can be used for a wide range of applications at different scales. Backed by the technology of ldquo3Srdquo, the study builds the SOTER-LUCC database in a moderate scale in Fujian province which has been applied in the assessment of the relative sensitivity of ecosystem to acid deposition and the suitable sites selection for Euphoria Longan in Fujian province and turned out to be feasible.
