摘要

90年代初

荷兰学者以荷兰南部黄土区土壤侵蚀和水土保持规划研究为基地

开发了基于土壤侵蚀物理过程和GIS的土壤侵蚀预报模型—LISEM(LImburg Soil Erosion Model)

为水土保持规划提供了一个支持工具。该模型考虑了土壤侵蚀发生的主要过程

可以与栅格GIS集成

并可直接利用遥感动态数据。由于对土壤侵蚀和水文学过程的认识以及土壤水分时空变异性的描述方法还不尽成熟

所以LISEM模型仍需要进一步改进。

Abstract

A new physically based soil erosion model LISEM

has been developed by the scientists of Netherlands

which can be used to predict soil and runoff and to make soil conservation and landuse plan in small catchment.The varied processes of erosion is incorporated in the model. LISEM is one of the first examples of physically based models that is completely incorporated in a raster GIS and digital remotely sensed data and can be easily applied in larger catchments. A-l though the model has several advantages over other models

it is far from perfect

so more at tention should be paid to the spatial and temporal variability of soil properties and description of soil erosion processes.
