摘要
归纳总结了土壤的不同功能,认为土壤不但具有作物生产功能,还是环境交互(缓冲、过滤、转化和循环)媒介,是动植物栖息地(基因库),同时为人类提供居住环境、原材料,此外,具有自然文化历史档案功能。本文根据相关性与代表性、灵敏性、通用性、可获取性与经济性,找出不同土壤功能的表征指标,并对其进行分类解译。土壤功能评价指标解译可以为土壤功能评价提供参考,增加土地管理与规划者对土壤的理解,为土地利用规划提供基础,有利于土壤与土地资源的合理规划与可持续管理。
Different functions of soils are summarized in this paper, which including the function of food production, the media of environmental interaction （buffering, filtering, transformation, and circulation）, the habitat （gene pool） of flora and fauna, the living environment for human, as the source of raw materials, and as the archive of natural and cultural history. Proper characterization indicators of soil functions are chosen according to the principle of relevance and representativeness, sensitivity, versatility, accessibility and economy of soil parameters, and the interpretation of these indicators is given out simultaneously. The interpretation of evaluation indicators of soil functions can provide references to the actual evaluation of soil functions, and it is also helpful to increase the understanding of land managers and planners with respect to soil. This study provides a basis for reasonable land use planning and sustainable management of soil and land resources.
