Wilayah Cianjur Utara terletak di pegunungan yang sumberdayanya melimpah, namunpertumbuhan penduduknya terjadi dengan cepat, sehingga akan terjadi penurunan dayadukung lingkungan karena tuntutan penduduk akan lahan terbangun. Prediksi terhadapdaya dukung lingkungan penting untuk dilakukan. Data kependudukan 2006 ndash; 2016dan citra Landsat 7 ETM 2006, 2011, dan 2016 digunakan dalam penelitian ini. Dayadukung diamati melalui model sistem dinamis hubungan antara pertumbuhanpenduduk dan ketersediaan lahan dalam kurun waktu tahun 2006 - 2100, kemudiandijadikan model dinamika spasial. Hasil prediksi model menunjukkan lahan terbangundari tahun 2026 ndash; 2060 berkembang pada wilayah yang sesuai hingga kurang sesuaiuntuk lahan terbangun.

North Cianjur region lies in the mountains with abundant resources, but the populationgrowth quickly, there will be carrying capacity decline because of population demandsfor built up land. Prediction of environmental carrying capacity is important to do, itwas observed through system and spatial dynamics model of relationship betweenpopulation growth and land availability in 2006 2100 period. Population data 2006 2016 and Landsat 7 ETM 2006, 2011 and 2016 images were used in this study. Modelprediction results shows that the built up land from 2026 ndash 2060 developing in asuitable until less suitable area for constructed land.
