摘要

本文评价了量测细沟侵蚀量的填土法和容积法。认为容积法简单易行

适于野外调查

但精度较低。为了提高容积法估算精度

通过资料分析

提出了野外调查量测细沟侵蚀量时的样方选择方法及具体量测和计算方法

并进一步通过资料分析

给出了根据容积法估算细沟侵蚀量的方程式。用这个方法量测和估算细沟侵蚀量简单、易行

精度也较高。

Abstract

This paper estimates methods of measuring rill erosion amount. It is admitted that volume method is simple

convenient and suitable to use in the feild

but its precision is lower. In order to improve its precision

the paper puts forward the method of choosing Yang and method of measuring and calculating estimated the rill erosion amount used the volume method in the field. By analysing data

the paper has further given linear equation calculaling precise value according to the measuring value of the volume method. The author considers that measuring and calculating the rill erosion amount used the method raised in this paper in the field is convenient and obtains precise value.
