摘要
土壤圈层内及其与其它圈层间的碳、氮、磷、硫、污染物及生物之间的 物质交换和能量传递过程,以及与土壤生产力,环境保护和人畜健康关系探 讨,是土壤质量研究的核心。首先对水稻土、红壤、潮土、黑土等四大类代表 性耕地土壤之质量演变的主要过程以及恢复、培育高质量土壤的技术开展研 究。同时将对土壤质量指标的量化表达、评价咨询体系及土壤质量时空变异 规律和建模等开展研究,从而提出不同级别的土壤质量标准建议和编制数值 化土壤质量图等,为国家的决策及建设提供服务。本文叙述了在我国开展土 壤质量研究的基础条件以及在研究思路上要宏观与微观相结合,在技术上要 重视建立土壤质量的物理、化学、生物学属性的综合评价体系等新观点。
The core of soil quality research is material (C,N,P, S and pollutants) and energy exchange, cycling within pe-dosphere and/or with hydrosphere, biosphere, atmosphere and lithosphere, its relationship with soil fertility and environmental quality. Quality evolution process and good quality cultivation techniques of 4 arable soils (red soils, rice paddy soils, chao soils and black soils) were chosen to deal with at first.Other new research areas of modern soil sciences are as follow: 1. Selecting the soil quality index and its quantitative expression; 2. Constructing soil quality assessment systems; 3. Reveal the time and space variation pattern of soil quality and modeling; 4. Create the regional or state level soil quality standard; 5. Editing the digital soil quality map etc.Based on the very broad traditional soil sciences achievements, modem soil sciences needs more combination of both macro and micro research, and comprehensive assessment of soil physical, chemical and biological natures as quality index system, to create new soil technology in supporting sustainable development of society.
