本研究之目的即在整合及分析土地利用变迁对水库淤砂之影响 ,以了解各水库对开发之容忍度 ,选择翡翠、石门及德基三座水库资料较为完整的水库集水区进行流量与悬移质浓度之分析 ,分析土地利用变迁对水库淤积之影响。本文中将淤积量与搜集之基本资料进行分析 ,将分析步骤分为三部分 :一是淤积量与气象水文资料之关系 ,二是淤积量与水库集水区面积之关系 ,三是悬移质输砂率之关系 ,希望能从这部分找出与淤积量较相关之因子。
The purpose of this study is to integrate and analyze the impact of land use changes on silt in reservoirs in order to understand the development tolerance of reservoirs and to choose the three intact reservoir water collecting areas of Jadeite, Analysis of suspended sediment concentration, analyze the impact of land use changes on reservoir siltation. In this paper, the amount of sedimentation and the basic data collected for analysis, the analysis is divided into three parts: one is the relationship between sedimentation and meteorological and hydrological data, the second is the relationship between sedimentation and reservoir catchment area, the third is the suspended matter The relationship between the rate of sand transport, hoping to find out from this part and siltation more relevant factors.
