我国水土流失面积约150万平方公里,平均每年流失土壤50亿吨。因此开展土壤侵蚀和水土保持研究,对保护土壤资源、发展国民经济都有重大意义。在研究工作中,需要对土壤的侵蚀量进行测定和预报。本文将讨论土壤侵蚀量真值估计值的求取和侵蚀量预测值的评分方法。一、对几个基本概念的理解目前,确定土壤的侵蚀量有几种方法: 1、利用水文观测或径流小区观测,根据测出的悬移质和推移质求出;
China’s soil erosion area of about 1.5 million square kilometers, the average annual soil loss of 5 billion tons. Therefore, to carry out soil erosion and soil and water conservation research, to protect soil resources, the development of national economy are of great significance. In the research work, the amount of soil erosion needs to be measured and forecast. This article will discuss how to determine the true value of soil erosion and how to estimate the amount of erosion. First, the understanding of several basic concepts At present, there are several ways to determine the amount of soil erosion: 1, the use of hydrological observations or runoff plot observation, based on the measured suspended sediment and bed mass obtained;
