摘要

本研究旨在了解利用Landsat 8影像形式的遥感数据，利用SAVI (Soil Adjusted vegetation Index，土壤调整植被指数)和MSAVI (Modified Soil Adjusted vegetation Index，改良土壤调整植被指数)方法绘制巴东市植被密度图的方式。这种类型的研究是定量使用数字数据。和分析，并以数值表的形式呈现数据，以比较巴东市土壤调整植被指数(SAVI)和改良土壤调整植被指数(MSAVI)方法的精度。本研究发现，SAVI (Soil Adjusted Vegetation Index)方法的精度测试结果为86.95%，而MSAVI (Modified Soil Adjusted Vegetation Index)方法的精度测试结果为91.30%。本研究采用SAVI (Soil Adjusted Vegetation Index)和MSAVI (Modified Soil Adjusted Vegetation Index)植被指数法，通过对各指数输入已确定的公式，来了解巴东市植被密度的形成情况。本研究的结果是利用SAVI (Soil Adjusted vegetation Index)和MSAVI (Modified Soil Adjusted vegetation Index)方法绘制的植被密度图，以及SAVI (Soil Adjusted vegetation Index)和MSAVI (Modified Soil Adjusted vegetation Index)精度检验结果的表格。

COMPARISON OF SOIL ADJUSTED VEGETATION INDEX (SAVI) AND MODIFIED SOIL ADJUSTED VEGETATION INDEX (MSAVI) METHODS TO VIEW VEGETATION DENSITY IN PADANG CITY USING LANDSAT 8 IMAGE

This study aims to see how the shape of the vegetation density map uses the SAVI (Soil Adjusted Vegetation Index) and MSAVI (Modified Soil Adjusted Vegetation Index) methods in Padang City using remote sensing data in the form of Landsat 8 imagery. This type of research is quantitative using numerical data. and analysis, as well as presenting data in the form of a numerical table to see a comparison of the accuracy of the SAVI (Soil Adjusted Vegetation Index) and MSAVI (Modified Soil Adjusted Vegetation Index) methods in Padang City. In this study, it was found that the results of the accuracy test of the SAVI (Soil Adjusted Vegetation Index) method were 86.95% while the MSAVI (Modified Soil Adjusted Vegetation Index) method was 91.30%. This research uses the SAVI (Soil Adjusted Vegetation Index) and MSAVI (Modified Soil Adjusted Vegetation Index) vegetation index methods by entering the formula that has been determined for each index to find out how the vegetation density forms in the city of Padang. The results of this study are maps of vegetation density using the SAVI (Soil Adjusted Vegetation Index) and MSAVI (Modified Soil Adjusted Vegetation Index) methods and tables of SAVI (Soil Adjusted Vegetation Index) and MSAVI (Modified Soil Adjusted Vegetation Index) accuracy test results.
