Hubungan Penggunaan Lahan dengan Bentuklahan di Daerah Pesisir Kabupaten Cianjur

Abstract

Java Island is the most dominant volcano area in Indonesia. Many volcano and different land form disseminate cause the variaty of land uses in Java Island. The aims of this research are to mapping land uses from IKONOS imagery, to mapping land forms from SRTM-30 Imagery, and also relation between land forms and land uses in south coastal Cianjur Regency. The mapping of land forms is done use SRTM 30 imagery based on approach of morphocronology, morphography, morphogenesys, and morphometryc. Land uses map is made with focus to some supporting interpretation keys in on screen deleniation. The most dominant land form in south coastal Cianjur Regency is old denudational volcanic mountain area (16.1%) that disseminate in east area. Seen by some land forms aspect (morphography, morphometryc, and morphogenesys), land uses in south coastal Cianjur Regency is dominated by forest, mix garden, and paddy field. Forest dominate at mountain area land form with rather steep slope until very steep slope from denudational volcanic process. Mix garden dominate at hill and valley area with slight until rather steep slope from vulcanic and fluvial denudational process. Paddy field dominate at plain land form with flat until slight slope from marine process. Based on double regretion analysis result between land uses as no release variabel and land forms aspect (morphometryc and morphogenesys) as release variabel, show that relation between both of them is significant influence according to statistics. The relation of both variabel have R2 value between 78% until 92% that is dominated influneced by morphometry aspect.
