A presente pesquisa objetivou a caracterização dos efeitos da altitude sobre o crescimento do Palmiteiro (Euterpe edulis). Para tanto foram definidas dez unidades amostrais ao longo de um gradiente de altitude, distribuídas sistematicamente com intervalos de 500 metros em um morro na formação Rio das Cobras com um raio com de aproximadamente 1500 m de extensão e com uma variação de 500 m na altitude. Para avaliação do Palmiteiro no gradiente altimétrico foram abatidos oito indivíduos de cada nível altimétrico, dos quais foram coletados os dados de biomassa total e a biomassa do creme comestível. Quando comparados os resultados encontrou-se tendências entre a produção de biomassa total e do creme em relação ao gradiente altitudinal. O SIG foi construído para retornar os valores de biomassa total e do creme e a densidade dos indivíduos na área, o que proporcionara informações para o planejamento florestal. QUANTIFICATION AND EVALUATION OF QUALITATIVE AND QUANTITATIVE PARAMETERS OF PALMITEIRO (Euterpe edulis MARTIUS) ALONG OF A ALTIMETRIC GRADIENT UISNG GEOGRAPHIC INFORMATION SYSTEM. Abstract The present research aimed the characterization of effects of altitude on growth of Palmiteiro (Euterpe edulis). It was defined ten sample plots, systematically distributed with 500m intervals, covering all gradient in the mound belongs to formation called Rio das Cobras with 500 m altitude. For the evaluation of the Palm in the studied area it was cut eight trees in each established level of altitude. The collected data were total biomass and biomass of eatable part. When compared the results it was find tendency between total biomass production and eatable part in relation to altitude gradient. The GIS was construct to find the values of total biomass and eatable part and the tree’s density in the area . The GIS will give important information to the forest management.

O geoturismo é um segmento da atividade turística em áreas naturais que visa à conservação, a divulgação e o uso sustentável de locais onde os aspectos geológicos, geomorfológicos e paleontológicos do meio físico se destacam por seus valores estéticos, científicos, didáticos, culturais ou econômicos. Buscando contribuir com métodos voltados a esse segmento do turismo, este trabalho objetivou analisar o potencial da cartografia digital na conservação, divulgação e uso sustentável de locais de interesse geológico-geomorfológico (geossítios) de Prudentópolis (PR), tendo como base revisão bibliográfica, trabalhos de campo e processamento de dados cartográficos digitais em Sistema de Informações Geográficas (SIG). Realizou-se caracterização de quatro geossítios, os quais estão inseridos geologicamente na Formação Teresina (Salto/Canyon do rio São João e Salto Barão do rio Branco/Vale do rio dos Patos) e na Formação Serra Geral (Salto São Francisco/Vale do rio São Francisco e Morro do Chapéu/Afloramento da Formação Botucatu). Os dados levantados foram disponibilizados em planos de informação e banco de dados georreferenciados no software de geoprocessamento Arcgis 9.3, o qual se revelou como um importante instrumento de elaboração de produtos cartográficos voltados à atividade geoturística. Geotechnology applied to conservation, disclosure and use of geoturistical attractive in Prudentópolis (PR, Brazil) ABSTRACT The geotourism is a segment of the touristic activity in natural areas which aims the conservation, the disclosure and the sustainable use of places where the geological, geomorpholocical and paleontological aspects of the physical environment stand out by their aesthetic, scientific, instructional, cultural or economic values. Aiming to contribute with methods directed to this tourism’s segment, this paper aimed to analyze the potential of digital mapping in conservation, disclosure and sustainable use of geological-geomorphological interesting places (geosites) in Prudentópolis (PR, Brazil), based on literature review, field works and digital cartographic data’s processing in Geographic Information System (GIS). The characterization of four geosites was verified, which are geologically inserted in Teresina Formation (Fall / São João River’s Canyon and Barão do Rio Branco Fall/ Patos’ River Valley) and in Serra Geral Formation (São Francisco Fall/ São Francisco River’s Valley and Chapéu’s Hill / Outbreak of Botucatu Formation). And the collected data were provided into information plans and georeferenced database in Arcgis 9.3 geoprocessing software, which has proved to be an important tool for developing cartographic products focused on geotourism activity.

Biomass Availability

The growing interest in the development of chains for the use of agroforestry biomass for energy demand, is due to the awareness they are a crucial element to mitigate the global climatic change effects. The true effort is to have a reliable estimation of biomass availability by some instruments like forest management plans, which allow to locate the forest supply and to know the forest biomass availability in a medium period. In this paper we carried out a decision analysis by geographic information system, in Tuscia Romana area comprising 11 municipalities for a total amount of 813 km2. An estimation was carried out taking into account the bibliographic data on the analyzed species, reporting the biomass in weight taken out by the forest cut utilization. A comparison was also performed in field on chestnut trees cut in a sampling area near Bracciano and in a close sawmill. The results show long, medium and short-term dynamics, but some critical points were found related to the process of estimation and to the real procurement of biomass in some years. The results suggest to be care in a possible project of a biomass plant.

Hierarchy Process

The main objective of this study is to apply geographic information system (GIS) and Analytic Hierarchy Process (AHP) in assessing rattan production potential. The methodological approach of this paper is analyzing environmental factors inside GIS through Weighted Linear Combination (WLC) method in order to identify and define areas of rattan production potential for sustainable management and harvesting at watershed protection and forest management board (WPFMB) of Nam Dong district of Thua Thien Hue province. The overall relative importance weights of factors and variables are estimated using pair-wise comparison matrix of AHP method. The study results showed that 91.2 % of total natural area has potential for rattan production, of which 40 % belongs to high potential group, 44.7 % belongs to moderate and 5.5 % belongs to low. The results of this study not only help the forest managers of Nam Dong WPFMB in planning rattan use effectively, but also create a rattan database for management and sustainable use of rattan resources. Keywords: Analytic Hierarchy Process, geographic information system, rattan production potential, Weighted Linear Combination.
