Abstract
Remote sensing instruments and methods have become widespread in all segments of agriculture and horticulture. Among the innovative development of remote sensing instruments, the 3D laser scanner is one of the newest technique, which overtop in the spatial data collection. Terrestrial laser scanning is an appropriate tool for identifying such biophysical parameters like the structure of trees and branches, growth of volume. Determination of these parameters are time consuming and complicated with traditional methods. The examination was carried out in the Study and Regional Research Farm of the University of Debrecen near Pallag. We used Leica ScanStation C10 terrestrial laser scanner to estimate volumetric properties of the intensive apple orchard. Two rows of the study area were surveyed, where the height and stem diameter of apple trees were measured with Geomagic Studio 12 GIS Demo Software. Based on the built-in algorithms, the volume of each tree were defined by the software. The measured and calculated data was correlated, and middle correlations were detected. Estimated volume results could be useful for further investigation such as CO2 fi xing, which is an important factor for ecological service of the plantation.

Summary
The Earth’s ecosystems provides to a wide range of benefits to humanity known as “ecosystem services.” This has given the present balance of human resource usage increasing attention is being paid in almost every area of science. The vegetation primary service is the production of oxygen, CO2 absorption and fixation, thereby contributing to the reduction of the greenhouse effect (Gyeviki et al, 2011). Trees have got the largest carbon sink potential in the ecosystem types. It became necessary to elaborate forest carbon sink capacity estimations. The role of vegetation is highly depends on some vegetation indices which correlate to the biomass, species and variety composition, spatial location, the leaf surface and volume of tree (Radó, 2001). The estimation of assimilated CO2 fixation in an orchard is especially necessary to define the volume of trees, because during the assimilation, the amount of absorbed and incorporated carbon dioxide appear in the plant biomass production (Kiss et al, 2011). Fruit orchards are artificial ecosystems, but they represent a significant biologically active green mass in the environment
