摘要
本文在总结了人为加速侵蚀研究的基础上,介绍了人口增长、政策导向、经济发展和土地利用变化4个方面社会经济因素对土壤侵蚀的影响,概述了国内外对影响土壤侵蚀的社会经济因素的研究方法。在以上综述的基础上提出了以后研究需要深入的3个方面:多学科交叉研究、社会经济学模型研究和区域差异化研究。
Based on the summarization of the research on man-made accelerated erosion, this paper introduced the four social-economic factors which affect soil erosion including population growth, policy, economic devel- opment and land use changes, and reviewed the research methods for the social-economic factors affecting soil erosion both at home and abroad. After that, it is proposed that three aspects of the research need further study： interdisciplinary studies, social-economic models and regional differences.
