摘要

为快速有效地完成第一次全国水利普查水土保持情况普查中30 000多个野外调查单元的土壤侵蚀模数计算

采用.NET平台并结合ArcEngine二次开发包

开发了基于中国土壤流失方程(CSLE)的土壤水蚀模数计算器软件。以陕西省安塞县野外调查单元数据为例

应用该软件进行计算并得到了野外调查单元的水蚀模数

将计算结果与手工操作ArcMap计算得到的侵蚀模数进行了比较。结果表明

利用水蚀模数计算器软件计算得到的结果准确可靠

并可极大地提高计算效率。该软件可用于区域水土流失调查水蚀模数的计算。

Abstract

In order to quickly and effectively compute the soil erosion modulus of more than 30000 field inves-tigation units in soil and water conservation survey(the first national water conservancy survey)

water ero-sion modulus calculator software is designed and developed based on Chinese soil loss equation(CSLE) by using. NET platform of microsoft and AcrEngine development kit. By taking the data of field investigation units selected in Ansai County of Shaanxi Province as an example

the software is applied to calculate the water erosion modulus of the units and the calculated result is compared with that by operating ArcMap with manual method. Results indicate that the calculated result using water erosion modulus calculator software is accurate and reliable

and it can improve the calculation efficiency greatly. The software can be used for water erosion modulus calculation in regional soil erosion survey.
