The aim of the undertaken research was an evaluation of the frequency of the dry and the wet months in the Opole Voivodeship in the months of May to September in1981-2010 years, in the view of the global warming. The dry and the wet months were characterized on the basis of hydrothermal index K, thermo-precipitation index A, standardized precipitation index SPI and the amount of the precipitation deficiencies and excesses of the late potato. The attempt of answering the question which of these indexes describe the moisture conditions of the vegetative season the best were undertaken.It was proved that the average frequency of months, in which the different level of draught's intensity was observed, was equal to 25% on the basis of the thermo-precipitation index A, 35% standardized precipitation index SPI, 36% hydrothermal index K, and 34% on the basis of the deficiencies precipitation amount. The average frequency of the wet months were counted to all four indexes and the values were: 23% on the basis of the thermo-precipitation index A, 23% standardized precipitation index SPI, 16% hydrothermal index K, and 29% on the basis of the deficiencies precipitation amount. The dependence between the four indexes and the yield of ...
The paper describes and evaluates the space of Stobrawski Landscape Park located in the north-western part of Opolskie Voivodeship. The study on natural and tourism values was conducted by the "classification-by-points" method. The following evaluation criteria were adopted for the natural values: forestation rate, heterogeneity, the occurrence of natural protection forms and the occurrence of surface water, while for the tourism values, the criteria included: cultural diversity, the number of objects of historical value, the length of tourist trails, the presence of educational paths, and the occurrence of accommodation and catering facilities. Three evaluations, namely natural, tourism, and comprehensive tourism-and-natural evaluation, were carried out. The Head Office of Land Surveying and Cartography data, specialist literature, and field research results were used. The conducted analysis revealed the spatial diversity of the park's assets, which allows the authors to suggest measures aimed at exploiting the tourism potential of the area concerned while observing the principle of sustainable development. In terms of the natural environment, the most valuable fragments of the area under study are river valleys, particularly the Oder river valley, and the north-western part of the park where, inter alia, 4 nature reserves are located. In view of the low tourism ...
