Objetivou-se com este trabalho avaliar a krigagem em modelos digitais de elevação (MDEs) SRTM e ASTER como subsidio ao planejamento da colheita florestal. Foram testados os seguintes MDEs: SRTM com 30 m e com 90 m de resolução espacial (RE); ASTER com 30 m de RE; SRTM com 30 m e com 90 m krigado; ASTER 30 m krigado; e MDE padrão, obtido a partir de carta planialtimétrica. Com auxílio dos MDEs, foram gerados mapas de declividade, de acordo com as restrições operacionais de máquinas utilizadas na colheita florestal. Os MDEs foram avaliados por análise estatística descritiva e quali-quantitativa. Os MDEs apresentaram forte dependência espacial da altitude. As diferenças da raiz quadrada do erro médio entre os MDEs provenientes de imagens SRTM e ASTER originais apresentaram pequena discrepância em relação aos MDEs krigados. Os resultados da análise quantitativa e qualitativa evidenciaram melhora por meio da krigagem nos MDEs SRTM com 30 m e 90 m de RE. Entretanto, o MDE ASTER 30 m não apresentou o mesmo comportamento, sendo melhor em sua versão original. O MDE SRTM 30 m krigado apresentou maior potencial como subsidio ao planejamento da colheita florestal, na ausência de MDEs em maiores escalas. |

This work had as objective to evaluate the floral sources available in a caatinga area as food source for honey bees grainsApis mellifera, in order to give subsidies to the development of sustainable bee keeping in Petrolina (PE). The study was conducted in the Experimental farm of the campus of Agrarian Sciences of UNIVASF. The collection of the botanical material was done each 15 days, from December 2010 to May 2011, trough walks in tracks of 1.500m. The plant species collected were in blooming and were being visited by honeybees at that moment. To be sure on the sources collected by the bees, five of them were collected at the moment they were entering the hive with pollen loads. Honey samples were also collected in five hives to make melissopalinologic analyses. The pollinic types were analyzed qualitative and quantitatively, being classified according to the percentage of occurrence as dominant, accessory, or isolated pollen. In the analysis of pollen grains of the corbiculae it was verified the presence of pollen grains of all plants collected during the experiment. Yet for these analyses, the plant species were classified according to the amount of pollen grains during the analyzed months. In December 2010 and January of 2011, there was accessory pollen of Euphorbiaceae, both with 20%. For February, March, April and May 2011, the family Fabaceae was dominant with 59%. Practically in all months were found isolated pollen. The families of larger incidence in the honey samples were Euphorbiaceae and Fabaceae. Therefore, these are the most indicated species to be inserted in not cultivated areas in order to have beekeeping production.
