Pemanfaatan Citra Landsat 7+ETM untuk Analisis Neraca Energi pada Beberapa Jenis Tutupan Lahan di Provinsi Jambi

Abstract

Landuse change has occurred in Jambi province. Forest changed into others land formation has effect for microclimate regions. This research is to estimate the character of albedo, energy balance and temperature in several landuse types in Jambi by using Landsat 7+ETM image. Vegetation density affects energy and radiationon balance. Area with high vegetation density has low albedo because coming radiation is trapped between vegetation canopies. Area with high density like forest and national park has a high net radiation. Proportion of energy balance is strongly influenced by land cover characters. Vegetations with high density has highest proportion of evaporation heat flux more than low density. Area with high vegetation density and high humidity cause low temperature. Either vegetation density, temperature is influence by altitude and surface character in receiving radiation.
