近年来，可持续土地利用和农业生态系统管理方面的传统和本土知识受到越来越多的关注，特别是在资源贫乏、投入少的小农耕作系统中。本文介绍了中国所在的长江上游四川丘陵区当地农民所称的一种传统耕作制度--“边沟北沟”和“条沙面土”。2002年冬季，在贾家村进行了实地调查、与农民和省长的访谈以及坡面样带土样的Cs-137土壤净流失量评估。利用Cs-137技术估算了采用传统土壤保持措施的地区的年土壤净流失量为24.15 t ha(-1)a r(-1)。与本研究中Cs-137法测得的105.80 t ha(-1)a r(-1)以上的现场最大土壤流失量和同类地区其他样地监测的42.21t ha(-1)a r(-1)的田间侵蚀率相比，这种传统的耕作制度在过去的几十年里有效地保持了坡地的土壤。(C)2006爱思唯尔B.V.保留所有权利。
Traditional and indigenous knowledge for sustainable land use and agro-ecosystem management has received increasing attention in recent years, especially in resource-poor, low-input and smallholder farming systems. The present paper introduces a traditional farming system, which is called "Biangoubeigou" and "Tiaoshamiantu" by local farmers in Sichuan hilly region, the upper Yangtze River basin of China. A field survey, interviews with farmers and local governors, and soil core sampling along a slope transect for Cs-137 assessment of net soil loss were carried out in Jiajia Village in the winter of 2002. Annual net soil loss in the area where traditional soil conservation approaches had been practised was estimated at 24.15 t ha(-1) yr(-1) using the Cs-137 technique. Compared with the highest on-site point soil loss of more than 105.80 t ha(-1) yr(-1) by the Cs-137 technique in this study and field erosion rate of 42.21 t ha(-1) yr(-1) from other plot monitoring studies in the similar area, this traditional farming system has effectively conserved soil on the slope land in the past decades.
