通过应用地理信息系统和数据库技术，并引入相对土壤质量指数（RSQDI）的概念，以千烟洲试验站为例，建立了在小区域水平上编制土壤质量变化图的方法．研究表明．地理信息系统与多时段土壤变化数据库相连，可以方便有效地实现土壤质量变化图的编制．土壤相对质量指数可以使得区域土壤有一个统一的比较标准，其变化量△RSQI可以作为在区域水平上编制土壤质量变化图和评价土壤质量变化的依据．本研究为土壤质量变化图的编制提供了借鉴，也为该区土壤质量和性质的进一步监测和评价提供了重要的基础数据方法．
Through the application of geographic information system and database technology and the introduction of the concept of relative soil quality index (RSQDI), a case of Qianyanzhou experimental station was taken as an example to establish a method for mapping soil quality at a small regional level. research shows. GIS is linked to a multi-period soil change database to facilitate the mapping of soil quality changes easily and effectively. Soil relative quality index can make the regional soil have a unified comparative standard. The variation △ RSQI can be used as the basis for preparing the soil quality change map and evaluating the soil quality change at the regional level. This study provides a reference for the preparation of the map of soil quality changes and also provides an important basic data method for further monitoring and evaluation of soil quality and quality in the area.
