土地资源信息系统在小流域规划中的应用

利用现代技术手段, 建立一个适应小流域治理规划与管理需要的计算机服务系统, 能代替许多日常繁琐复杂的信息处理, 使规划更具科学性和规范性, 缩短规划制定周期, 及时满足水土保持工作的需要。以GIS工具软件包为核心、将地形图和相应的各种相关数据、文字资料输入计算机并作为基础数据, 并使这两大类数据建立起一个逻辑关系, 使社会、经济、自然、人为要素与空间坐标有机地结合起来。运用计算机高级语言对系统管理的数据进行线性与非线性、动态与静态、多目标规划设计方案等, 并与专家系统的综合分析评价相结余, 形成一个土地资源信息系统（HHRLIS）。

Application of Land Resource InFormation System to Small Watershed Program

A computer service system.which was suitable for program and management of small watershed harness, was designed by modern technology, it could replace many daily complicated work of information processing, enable the program more scientific and normal.shorten the period of program formulation.and satisfy the needs of soil and water con"ervation work in time.The system takes GIS as the key, reads topographic map, relevant data and characters into computer as the basic data.makes two kinds of this data to set up a logical relationship, and combines factors of society.economics.natural and human activity with space coordinate as an organic whole.The system managed data ate analyzed synthetically with methods of integrating linear and unlinear, statte and dynamic and multiobjective plan etc.with expert system, then, the HHRLIS system is set up by using higher computer language
