Determinación del estado fisiológico en una plantación de pinus radiata D. Don, mediante técnicas de teledetección en la comunidad de Totoras, parroquia Achupallas, cantón Alausí, provincia de Chimborazo

Abstract

This investigation propones: determine the physiological state of a Pinus Radiata D. Don plantation, through remote sensing techniques in Totoras community, Achupallas parish, Alausi canton, Chimborazo province. The technics to develop this work consisted of remote sensing, mainly images satellite Rapidely, and its integrations to SIG. To the field work it was used GPS measure tapes, field form, forcipula, inclinometer. For the remote sensing was used Rapideye imagines with 5.5 meters resolution, the software ENVI 5.0 and ArcMap 10.3 with helped to do maps on NDVI of the plantation. In the field was determined the physiological condition from the cubic meters of each parcel, these data were checked with data proportionate by ACOSA that show us that a parcel healthy of 500 m3 will have 20 m3 as minimum and a sick 10 m3, the results also were compared with the studies of Murillo & Camacho, 200 were rated the parcels quality with the DAP coefficient of variation, comercial and total height show us a healthy parcel value is < 10% and of a sick > 20%. These parcels evaluated in the field, were analyzed in the satellite image starting from the calculation of NDVI, which show us to healthy parcels a value of 0, 53 and sick 0,35, where the final results were the same results obtained in field coinciding each parcels like healthy and sick respectively. These results are applicable to other forest species plantations exist in Ecuador, and can be used in native forests allowing us to evaluate their status and the ecosystem surrounding it.
