Land surface temperature changes in northen parts of bandung basin

Abstract

Bandung Basin is unique because it consists of flat to mountainous areas. As in the Northen parts of Bandung Basin, the north is steeply sloped and is located in the Tangkubanparahu volcano and Mount Burangrang. Topographic variations in the Northen parts of Bandung Basin affect vegetation cover and temperature according to the height of the place. Various type in vegetation greenness and temperature can be analyzed by applying remote sensing. The aims of this study are : 1) Identification of land surface temperature in the northen area of Bandung Basin in 1990 - 2018, 2) Estimating the greenness of vegetation in the northen area of the Bandung Basin in 1990 - 2018. The method used is information extraction through multi-temporal remote sensing imagery to obtain land surface temperature and greenness of vegetation in the northen parts of Bandung Basin. The results of this research show temperature is getting hotter in the period of 1990 to 2018 while the greenness of the vegetation is decreasing, as indicated by forest vegetation, pine forests, tea plantations, grass, rice fields, and bushes increasing LST values and decreasing SR values. In contrast to agriculture, SRI values actually increase with LST. This can be caused by changes in agriculture to other land cover, or the type of plant is changes. It is recommended that the northen parts of the Bandung Basin should maintain the greenness of the vegetation to control the stability of the temperature because most types of vegetation have increased LST and decreased SRI especially in urban areas.
