微机系统在黄土高原小流域治理规划中的应用

在彩红外航片解译和补充调查土地利用现状及地块特性因子基础上,利用微机建立小流域土地资源数据库,进行土地资源的统计、检索和评价,并按线性规划的方法进行多方案、多目标的土地利用结构优化计算,采用CAD技术绘制规划图,使小流域综合治理规划工作系列化、程序化,从而提高了规划工作自动化程度、规划质量和速度,为小流域水土保持综合治理规划提供了一套科学、快速的方法。

Application of Micro-computer System in the Planning of Small Watershed Harnessment in the Loess Plateau

In the past, the planning of soil and water conservation was worked out by simple calculation work, which is labor and time consuming. The author discusses a new method, that is to use micro-computer to replace the overlaborate procedures in working out the small watershed harnessment plan systematically. At first, aided by micro-computer hard and soft-wares, a data base of land resource is built up by using investigated data. Then, this data base is used to carry out statistics, data retrieval, evaluation of land resources as well as appraisal of plot development. Based on these, the linear-programme method is used to optimize land utilization structure. Finally, CAD technology is used to make maps.
