摘要

With a high-resolution Airborne Laser Scanner (ALS) the topography of peatlands was measured in August 2007 by a helicopter. With this modern technology we achieve a 3-dimensional Digital Elevation Model (DEM), hydrological data, and biomass data and combined with peat drillings the amount of carbon storage. The ALS-resolution is in elevation (z) +/-15cm and in x- and y-direction 0.5m. Compared to SRTM-images with 90m x 90m x 5m and Landsat-Satellite-images with 30m x 30m (without elevation) we got much better knowledge of peatlands. DEMs are divided into two types of groups. The Digital Surface Model (DSM) gathers information by Laser Scanner with trees, bridges and house and the Digital Terrain Model (DTM) is filtered using the DSM and shows the topography of landscape without trees, bridges, houses etc. The infra-red Laser sends 100,000 pulses per second and receives many of them in the detector and determines the distance to the different objects. To understand better the situation of that area peat drillings have been done in 4-2006 parallel to the Kalimantan highway along the transect Tangkiling and Kasongan and in 7-2007 from Katingan river to the transmigration village Habaring Hurung south of Tangkiling. Results of these peat thickness measurements showed a peat depth up to 8-10 metres. The peat surface with peat dome was measured along the two transects using the ALS technology with 49.1m res. 40.8m. The airborne laser penetrates the Peat Swamp Forest (PSF) and reaches the peat surface. We measured an average tree height of 35m. The stored peat volume and carbon for the northern Sebangau Catchment and Palangkaraya between Katingan and Rungan rivers up to the border of the heath forest has 7.1 Gm~3 (res. 5.93 Gm~3) peat volume. The content of carbon in 1 cubic meter of peat has been measured and is 154.3kg (res. 131kg). We found by ALS-measurements and peat drillings and interpolation a stored carbon value of 0.92 to 1.1 Ctons for this area.
