“在土地资源方面,许多国家乃缺乏全面的数据,侵蚀区域扩大业已发生,并且看来还将成为公害”(Hauck,1985)。Walling 强调,在流域研究中,需要有一种简便技术,来测量长期性土壤流失的时空分布;为了标定和测试现有的各种土壤流失模型,也需要土壤侵蚀速度数据。本文回顾了近10年来,自然状况下土壤侵蚀测量技术的进展情况。土壤水蚀和风蚀的量测技术,可以分为小区域收集器法,各种测量方法,和示踪法三类。
“In terms of land resources, many countries lack comprehensive data, and the erosion of the region has taken place and will appear to be a nuisance” (Hauck, 1985). Walling emphasized that there is a need for a simple technique to measure the spatial and temporal distribution of long-term soil loss in watershed studies. Soil erosion rates are also needed to calibrate and test existing models of soil erosion. This paper reviews the progress of soil erosion measurement technology under natural conditions in the recent 10 years. Soil erosion and wind erosion measurement techniques can be divided into small area collector method, a variety of measurement methods, and tracer method three categories.
