摘要

空间分析功能是GIS的本质特征。选择黄土高原小流域退耕还林(草)工程为研究对象

以探讨GIS空间分析在退耕还林(草)工程中的应用方法为目标

确定了一种基于GIS空间分析的黄土高原小流域退耕还林(草)规划方法;建立了相关地理编码体系和规则

并运用GIS空间分析的坡度分析、坡向分析、叠置分析、属性分析等功能实现了规划的全过程

完成了黄土高原小流域退耕还林(草)规划图以及退耕地还林面积和还林规划面积统计。结果表明

此方法在以小流域治理为特点的黄土高原地区退耕还林(草)工程实施中有借鉴意义。

Abstract

The spatial analysis is an important function or a characteristic of GIS.The article chooses the project of converting farmlands to forestry or grass land in the small watershed on Loess Plateau as an object of studying

aiming at researching new methods for applying GIS spatial analysis into the project.Firstly

a new scheme of converting farmlands into forests or grass adapting to the areas based on GIS spatial analysis and rules of geocodes were made.Secondly

using the functions of GIS spatial analysis including slope analysis

aspect analysis

overlay analysis attributive analysis finished the whole process of planning.Finally

the planning map and area statistis tables about converting farmlands into forests or grass land in the small watershed were obtained.The results show that the method may be used in the course of carrying out the project of converting farmlands into forests or grass on the loess plateau with the characteristics of thesmall watershed.
