摘　　要：选择闽东南典型丘陵台地区的漳浦部分地区为样区,依托SOTER理论和地理信息系统技术,编制样区地貌图、岩性图、坡度图和土系图,叠加生成地形体、地形体组分和土壤组分3级SOTER单元。SOTER属性数据库包括图斑信息表、景观环境数据表、典型单个土体数据表和土壤发生层数据表。1:1万的大比例尺SOTER数据库,初步应用于漳浦样区景观生态系统稳定性分析,将地形体图层与土地利用图叠加,计算出各项景观格局指数,揭示了该样区景观生态系统处于结构单一、功能低下、稳定性差的现状。Based on the SOTER methodology and GIS, a local level SOTER database in an experimental plot of Zhangpu County was upbuilt in the study. The relief map, lithology map, gradient map and soil series map were compiled firstly, then the maps were overlaid to produce three levels SOTER units including terrain, terrain component and soil component. The SOTER attribute database consisted of four parts; the map delineation information table, the landscape environment table, the typical pedon table and soil horizon table. Besides, the application of the SOTER system was explored by overlaying the terrain map and the landuse map to calculate the landscape pattern indices. The results indicated that the landscape ecosystem of the experimental plot is in a situation of single structure, low function and unsteadiness.
