中国土壤信息系统（SISChina）及其应用基础研究

土壤是人类赖以生存和发展的物质基础,是陆地生态系统的核心,为了在全球尺度、国家尺度和区域尺度上解决资源、环境和生态的有关问题,就必须要建立土壤信息系统。本文首先全面系统地介绍了国内外有关土壤信息系统的研究进展,阐述了中国土壤信息系统建设的数据源、土壤空间数据和属性数据、包含土壤空间与属性数据融合的中国1:100万土壤数据库及其应用基础,这对了解中国土壤信息系统的发展趋势,更好地利用土壤资源,为农业生产和生态环境建设服务具有重要的现实意义。

Soil Information System of China (SISChina) and Its Application

Soil is the material basis for human beings to live and develop on and it is the kernel of the terrestrial ecosystem. In order to solve problems in the fields of resources,environment and ecosystem,it is essential to establish a soil information system. A systematic review of researches of soil information systems home and abroad was presented here,introducing in detail sources of the soil data of the SISChina,soil spatial data,soil attribute data,China 1:1,000,000 soil database and its application. The introduction was of great practical significance to readers and researchers to get to know the developmental trend of the SISChina and make more effective use of the soil resources in agricultural production and eco-environment construction in China.
