摘要
本研究旨在利用遥感、GIS和野外观测相结合的方法,研究兰邦曼库拉特大学KHDTK地区归一化植被指数(NDVI)与地表温度的相关性。结果表明:KHDTK地区NDVI值在0.07 ~ 0.88之间;基于图像分析结果与野外观测结果验证的地表温度估算范围为25.60℃~ 31.90℃。地统计相关分析结果得到方程y = 35.5551 ~ 8.86213x,决定系数(R2)为0.3623,相关系数(r)为0.6019。由该方程可以解释为NDVI与地表温度呈负相关或成反比,且呈强相关水平。penelitian ini bertujuan menganalis korelasi nilai归一化植被指数(NDVI) dengan suhu permukaan tanah di KHDTK Universitas Lambung Mangkurat menggunakan teknik kombinasi antara penginderaan jauh, SIG dan observasi lapangan。Hasil penelitian menunjukkan pada地区KHDTK nilai NDVI berkisar antara 0,07 sampai 0,88。Estimasi suhu permukaan tanah berdasarkan validasi antara suhu hasil analysis citra dengan hasil observasi lapangan berkisar antara 25,60°C sampai dengan 31,90°C。Hasil分析韩国地质统计didapatkan persamay = 35,5551 - 8,86213x dengan nilai koefisien determinasi (R2) sebesar 0,3623和koefisien korelasi (r) sebesar 0,6019。Dari persamaan terterbut dapat diartikan antara NDVI dengan suhu permukaan tanah memiliki korelasi - negative(消极的)berberding(消极的)terbalik dengan tingkat hubungan korelasi kuat
ANALISIS KORELASI NILAI NORMALIZED DIFFERENCE VEGETATION INDEX (NDVI) DENGAN SUHU PERMUKAAN TANAH DI KHDTK UNIVERSITAS LAMBUNG MANGKURAT
This study means to examine the correlation of the Normalized Difference Vegetation Index (NDVI) with the land surface temperature at KHDTK of Lambung Mangkurat University using a combination of remote sensing, GIS, and field observations. The results showed that in the KHDTK area, the NDVI values ranged from 0.07 to 0.88. The estimation of land surface temperature based on the validation between the temperature of the image analysis results and the results of field observations ranged from 25.60°C to 31.90°C. The results of the geostatistical correlation analysis obtained the equation y = 35.5551 – 8.86213x with a coefficient of determination (R2) of 0,3623 and a correlation coefficient (r) of 0.6019. From this equation, it can be interpreted that NDVI and land surface temperature have a negative correlation or are inversely proportional to the level of a strong correlationPenelitian ini bertujuan menganalisis korelasi nilai Normalized Difference Vegetation Index (NDVI) dengan suhu permukaan tanah di KHDTK Universitas Lambung Mangkurat menggunakan teknik kombinasi antara penginderaan jauh, SIG dan observasi lapangan.
