Megjegyzések:	Sedimentological investigations and thermal analyses were carried out in a steep slope vineyard in 2007 (Nagy-Eged hill - located in the north-eastern part of Hungary). This area is proned extremely eroded due to its significant steepness and vine-growing cultivation. Soil thickness is approximately 50 cm near the top while at the bottom the thickness of horizon A alone reaches up to 150 cm. According to the results the ratio of fractions smaller than 0.02 mm and those larger than 2 mm between the top and the bottom is reverse. In the lower slope section the ratio of particles smaller than 0.02 mm is three times that in the upper slope section. Similarly the ratio of particles larger than 2 mm in the lower slope section is five times that in the upper slope section. The quantity of clay minerals measured by thermal analysis is larger than that measured by elutriation indicating that a part of them exceeds the diameter of 2?m. Our results revealed the effects of soil erosion on the mineral composition of the soil. The amount of clay minerals (e.g. montmorillonite) is about the double in the lower section, than in the upper of the slope. Clay minerals caused negative water budget in the upper levels resulting in the occurrence of anthropogenic water deficit as the consequence of soil erosion. Therefore vegetative growth of plants in the lower areas is better than that of those in the upper areas.

Cím:	Firewood consumption and CO2 emission of detached houses in rural environment, NE-Hungary / Paládi Mónika, Szabó Szilárd, Megyeri-Runyó Anna, Kerényi Attila

Megjegyzések:	We aimed to study the CO2 emissions of detached houses using firewood for heating, using the example of a Hungarian village (Milota). We presented Hungary's CO2 emission structure and discussed the increasing ratio of firewood heating in households in relation to the increasing level of poverty in the population and the increasing price of natural gas. The annual firewood consumption of 22 households in an eastern Hungarian village in a rural environment was measured and the associated CO2 emissions were calculated. We found that the material of the walls was relevant; however, age structure was not important in the volume of the burnt firewood. Outdoor temperature determined significantly the amount of combusted wood and the analyses also revealed that heating habits (considering the daily routines of weekdays and weekends) can also influence CO2 emissions. It is argued that using firewood for heating is beneficial at both local and national levels since the absorption capacity of forests in Hungary can keep pace with firewood combustion emissions; although, they can absorb only 48.6% of total household CO2 emissions. At a global level, however, firewood combustion increases the CO2 content of the atmosphere.

Cím:	Long-term changes of land use/land cover pattern in human transformed microregions - case studies from Borsod-Abauj-Zemplén county, North Hungary / Sütő László, Dobány Zoltán, Novák Tibor József, Adorján Balázs, Incze József, Rózsa Péter

Megjegyzések:	Using historical geographic and landscape ecological methods three North Hungarian landscape units that underwent different types of anthropic impact were studied. Viticulture in the Nagy Hill of Tokaj was founded more than eight centuries ago, however, due to economic crises and the phylloxera epidemic extension of the vineyards has fallen to less than one-half during 250 years; wetlands and grassland of the Taktaköz were changed by arable lands after river regulation and flood prevention performed in the second half of the 19th century; and traditional land use/land cover pattern of the East Borsod Coal Basin has been transformed by coal mining and industrialization from the end of the 19th century. On the basis of study on transformation of land use/land cover patterns, consequences concerning landscape planning of the studied areas can be drawn. (1) Vineyards of the Nagy Hill of Tokaj have represented a traditional land use category in the area for many centuries; therefore, re-plantation of the abandoned vineyards would be the reasonable purpose. (2) In the Taktaköz arable lands have become dominant land use elements. Although the recent land use pattern can be regarded as traditional, the ancient wetlands and grasslands could be, at least partly, restored by significant landscaping work. (3) In the East Borsod Coal Basin the extension of forest has spontaneously increased after the closure of coal mines, therefore, the pre-mining landscape pattern could be more-or-less restored without considerable landscape transforming action.

Cím:	Tools for Landscape Ecological Planning : Scale, and Aggregation Sensitivity of the Contagion type Landscape Metric Indices / Szabó Szilárd, Csorba Péter, Szilassi Péter
Dátum:	2012
Megjegyzések:	The major objective of this study is to investigate the aggregation (class number), and scale (cell size) dependence of the contagion landscape indices. A detailed statistical analysis of theoretical habitat patterns using 1 km cell size, 64 and 81 ha areas has been delineated. Simple aggregated and dispersed, regular and irregular patterns were created, and their characteristics were revealed by using contagion type landscape metrics (aggregation, intermixing and subdivision indices) on the class and landscape level, as well as the influence of the number of classes and spatial resolution in their values. Cross-correlations were also explored. Our results show that all metrics are sensitive to the number of classes; they produced different values using the same pattern for 2-3-4 classes, except with the Aggregation Index. Resolution (cell size) has a significant effect on the values of the aggregation indices: comparing the applied 100, 250 and 500 m resolutions to the native 1000 m, it has been observed that the range of values decreased to half of the possible. This means that aggregation indices need a heuristically determined cell size that differs from the needs of other metrics. This study highlights that the interspersion and subdivision indices are not scale dependent landscape indices. Aggregation metrics (Aggregation Index, Percentage of Like Adjacencies, Clumpiness Index) and subdivision metrics (Effective Mesh Size, Splitting Index, Division Index) do not correlate with each other, but they are in a strong relationship within their groups. The Interspersion Index does not correlate with these landscapes metric parameters; its application can be recommended due to its uniqueness. Despite the strong correlations, it is advisable to use the indices in parallel according to the differing calculation methods on landscape ecological planning. Cross-correlation matrix changes with the grain size, but it is not significant.
