摘要

概述了国内外土壤容许流失量(T值)研究的历史、目前研究的现状和未来的发展趋势。对T值研究的主要内容如成土速度、土壤养分流失、泥沙淤积损失、土壤流失与土地生产力的关系、保护沟道侵蚀的重要性等做了详述。介绍了T值的数学表达和不同国家的T值标准

阐述了进行T值双值性研究的必要性。并对T值研究中存在的问题进行了分析。

Abstract

The history

present situation and developing trend of soil loss tolerance research are out lined. The main content in Tvalue research including soil formation rate

soil nutrient loss

off-site sediment damage

relationship between soil loss and soil productivity

and gully prevention is discussed in details. The mathematical expression of soil loss tolerance and Tvalue criteria in different countries are also introduced. The existing problems in Tvalue research and significance of making double Tvalue research are analyzed as well.
