摘要

坡度是最基本的地貌形态指标

它对地表物质能量迁移转换具有重要影响。阐述了坡度研究的几个主要方面

包括坡度分级与坡度制图方法

DEM建立方法和DEM类型对坡度的影响

DEM分辨率对坡度的影响

坡度衰减和坡度变换研究等。指出传统坡度研究方法已与GIS的发展

DEM的广泛应用不相适应

也不能满足水文和土壤侵蚀定量模拟研究的需要。指出应从改善DEM质量和DEM对地形描述能力入手

将DEM及其基础上提取的坡度视为空间上连续变化的表面

引入数字图形图像处理方法

以区域尺度径流与土壤侵蚀模拟及其相关的数字地形分析为服务对象

对坡度问题展开系统研究。研究重点应包括:DEM类型对于坡度的影响

坡度衰减原理

坡度变换方法与变换结果应用等。

Abstract

As an essential factor of landform

slope gradient has impacted the processes of transformation of materials and energies.The main researches on slope have been reviewed

including slope mapping

slope effects of DEM type

slope scale effects involved to DEM resolutions

and transformation of coarser resolution DEM derived slope.The main problems puzzled researchers on slope is slope mapping methods

in which slope was thought of discrete data and mapping for each of the classes.These methods were not matched to development of GIS and DEM applications

and do not meet the requirements of modeling in watershed hydrology and regional soil erosion as well.Considering the application of slope in hydrology and regional erosion modeling

the vegetation suitability assessing and mapping

main topics to be studied on slope include effects of DEMs from varied interpolation strategies

mechanisms of reduction for coarser resolution DEMs derived slopes

methods and model for coarser slope transformation

and application of scaled slope surface in studies of hydrologic and erosion models at the regional scale.
