PENENTUAN BLOK PENGELOLAAN CAGAR ALAM TANGKOKO – CAGAR ALAM DUASUDARA DENGAN PENDEKATAN SISTEM INFORMASI GEOGRAFIS (SIG)

Abstract

ABSTRACT
The objective of this study is to develop Tangkoko - Duasudara Nature Reserves management blocks using Geographic Information Systems approach. The overlaying methods of thematic maps were used to blend land cover, elevation, slope, and distribution of wildlife species. Social data included demographic data in the surrounding area of Tangkoko - Duasudara Nature Reserves. Management block criteria and scoring refer to Peraturan Pemerintah Tentang Tata Hutan dan Penyusunan Rencana Pengelolaan Hutan, Pemanfaatan Hutan dan Penggunaan Kawasan.
The result showed that Tangkoko - Duasudara Nature Reserves are divided into three blocks, namely Restoration/Rehabilitation Blocks (1724.29 ha; 23,22%), Jungle Blocks (4.251,41 ha; 57,26%), and Core Blocks (1449,30 ha; 19,52%). Restoration/rehabilitation blocks are spread into five places and physically characterized by moderate slope, medium altitude and low species density. Land cover is dominated by open land and agriculture. Jungle Block are spread into three places and characterized by plane to medium altitude and high species density. Secondary forest is the dominant land cover. The Core Blocks are spread into two places and characterized by steep slopes, high altitude, high species density. The land cover is dominated by secondary forests.
