    摘要:

    现代土壤学研究的总方向应是,“研究土壤圈物质组成、性质和物质循环、能量转化及其对人类生存环境,特别是农业持续发展的影响”,这是当前自然科学发展及资源环境形势影响下,对土壤学研究提出的新趋向。今后土壤学必须为人类享有充足的食物和清洁的环境作出贡献。土壤肥力是建立持续农业的重要物质基础,通过调节肥力退化与重建过程,不断培育持续高产的土壤肥力是建立持续农业的根本措施。必须注意调节N、P、K施肥比例与平衡施肥;充分发挥农田养分再循环的肥源潜力与不断防止土壤养分退化。现代土壤学在促进我国农业持续发展中的重要研究内容应包括持续农业与土壤圈物质循环;土壤肥力与农业持续发展;土壤水分平衡与调控等方面的系统与长期的定位研究。

    Abstract:

    The general direction of research work on soil science should be "to study the material composition, properties, cycling and energy transformation of materials in pedosphere and their effects on human living environment, especially on the sustainable development of agriculture",which is a new proposed tendency of studies on soil science under influences of current situation of natural science development and resource environment. Soil science must make an important contribution to that mankind enjoys enough foods and a clean environment. Soil fertility is a primary material base for the establishment of sustained agriculture, and continuously promoting soil fertility to get stable high crop yields via regulating the deterioration and rebuilding processes of soil fertility is the fundamental measure to establish sustained agriculture. Much attention should be paid to the regulation of N, P and K fertilizer ratio and balance fertilization, to the promotion of nutrients recycling in farmlands and to the prevention of soil fertility deterioration. Most important researches of modern soil science in promoting the sustainable development of agriculture in China should involve systematic and long-term experimental studies in many aspects such as sustained agriculture and material cycling in pedosphere, soil fertility and sustainable development of agriculture, and soil water balance and regulation.
