Characterizing Spatial Distribution Patterns of Direct Solar Radiation in Jieba Mountain Using GIS
摘要
Abstract
The spatial distribution patterns of direct solar radiation were investigated in Jieba mountain based on the function of solar radiation calculation in ViewGIS.The purpose of this study is to provide preliminary data and scientific evidences for regional planning and environmental construction.The results of spatiotemporal distribution analysis show that the direct radiation increased with the elevation.Greater amount of radiation were found at plantation and less at lower parts of the hills.The calculated radiations were found in descending order at the locations of plantation,flood land,summit,middle and upper part of hill,gully,and lower part of hill.On the other hand,direct radiation decreased with the increase of slope degree.The direct radiation also varied with slope aspects;sunny slope,semi-sunny slope,semi-shady slope,and shady slope had direct radiation in descending order.关键词
