摘要

坡耕地退耕还林 (草)是我国黄土高原地区、特别是黄土丘陵沟壑区实施水土保持和生态环境建设的基本方法之一

如何快速了解区域土地利用现状是实施这一工程的关键所在

传统的统计法和图上量算法均无法满足科学高效的要求。结合黄土丘陵沟壑区地形特点

研究并探讨了应用 GIS技术实现该地区土地利用状况快速清查的工作过程及关键技术

以期为在全区实现土地资源调查、规划、管理的科学化、自动化、标准化提供可供借鉴的方法和依据

Abstract

One basic method for the soil and water conservation and ecologic environment constructions in the loess plateau

especially the loess hill and gully area is to return the hillside cultivated land for forestry and grassland. The key issue to execute the project is how to rapidly learn about the current land use situation of the area. The traditional statistical method and on map measurement method are unable to meet the requirements of scientific high efficiency. Combined with the topographic features of the loess hill and gully area

the working process and key technologies of using GIS technology are studied and explored to realize the rapid inspection and checking on the land use situation so as to provide valid methods and basis to realize the automatization and standardization of scientific investigation

planning and management for the land resources in the whole area.
