E:ast Kalimantan as largest province in Indonesia has big problems, illler alia are degradation farm, floods. flora and fauna destntction, and contribution to change of global climate and global warming. River basin zone of Karang Mumus broadly 32,196.3 ha is river basin in &st Kalima11ta11 wilh level of damage at first priority, at present there is marginal field area have /arg<; 9, 106 ha. Purpose of this research was evaluate agroforestry landscape characteristic of Karang Mumus river basin. Based 011 spatial and temporal analysis that has done on Landsat/ satellite image in 1992 and 2007, the composition of settlement area was increased out from 1,277.l ha became 1,926.9 ha, it means increased 649.8 ha (50.9%); abandon land was increased out from 119.5 ha became 712. 7 ha (495.5%); .shntbs land was increased out from 25,297.4 ha became 25, 762.l ha (J.8%). On the contrary. cover type and land use form the agriculture of wetland was decreased out from 1,034.8 ha became 807.8 ha (- 21.9%); dry/and agriculture was decreased out from 170.9 ha became 99.3 ha (-41.9%); and secondary forest was decreased out from 3,969.5 ha became 2,540.5 ha (-36.0%). Mostly of the lessen wetland of agriculture area . dry/and agriculh1re, and secondary forest were caused by the occurrence of land use changing !hat they became settlements, shrubs land, and abandon land Temporal analysis of Landsat image between 1992 and 2007 explained that /and uses and cover types of settlement. abandon land, and shmbs lands were improved. Those changes have affected wetland agriculture, dry land agriculhire, and secondary forest degradation.
