摘要

为了揭示水分资源的空间变化特征

满足地质勘探、地质灾害预报、设施农牧业工程、工农业基地工程的建设以及开发利用降水资源各用户的需求

利用GIS工作平台

采用傅抱璞先生提出的半经验半理论气候资源回归模拟方法

将呼伦贝尔市水分资源推算到3″×3″小网格上

建立的41个表征水分资源空间分布模型

34个通过了极显著性检验

7个通过了显著性检验。有88%的模型回代检验和83%的模型模拟检验的平均相对误差均在-5%～5%之间

从而实现了水分资源快速、准确的查算。在此基础上分析了水分资源的空间变化规律

为该地区充分合理利用水分资源提供科学依据。

Abstract

This study aims to reveal the spatial distribution of water resources and meet the various demands for geological survey

geological disaster prediction

facility agriculture

and constructions of industrial and agricultural bases

as well as the development and utilization of precipitation resources.Twenty-four spatial distribution models of water resources in Hulun Buir City are constructed by using GIS techniques and Pu Baofu theory on climate resource simulation. Water resources in the city are manipulated in a number of "3×3" mini grids.Thirty-four out of the 41 models pass the very significant test

and 7

the significant test. The average relative errors of tests for the models are between-5% and 5%. In this way

the rapid and accurate calculation of water resources has been accomplished.Accordingly

the spatial distribution of water resources is analyzed. The study lays a scientific foundation for the sufficient and rational use of water resources in the region.
