In areas of high natural beauty and landscape values the main problem is to maintain a balance between the protection and sharing. Over-activation of tourism and holiday traffic may lead to the irreversible degradation of the landscape or the destruction of its most important components that determine the attractiveness of the place. In this regard, reasonable, balanced Policy and practice of spatial development of such areas should be guided, as a long-term goal, the need to preserve the attractiveness of the place, rather than temporary economic interests. This requires a prior inventory of such places, a proper assessment of their values and recognize the existing situation on the ground, including for possible corrective action to restore the attractiveness of the place. An important role in these activities are suitable layout and demarcation of hiking trails and their landscape valorization.. This issue have been analysed on an example of the valuation of landscape attractiveness along a chosen hiking tourist route (Bolesławów - Kletno - Hala pod Śnieżnikiem - Śnieżnik) in the Massif of Śnieżnik in the East Sudety Mts The valuation of landscape was based on giving points to individual elements of landscape on a scale 1-5. At each point along the route, 10 elements of landscape was subject to an assessment. They are: terrain, flora, fauna, water, process and cultural transformation, the elements of the cultural environment, composition, color, originality and visual experience (individual assessment). Detailed rules for the assessment contained in the master table. Scoring for each stage of the route has been averaged. As a result, it was established an impressions curve on a graph, showing the variability along the landscape. Based on the obtained scale values of the landscape, along a route was determined areas with a very high, high, medium, low and very low values of landscape.

В исследованиях, проведенных в период 42 дней на 32 молодых гусаках, разделенных по жребию на 8 групп, скармливали концентрированные смеси со стандартным содержанием вит. А (10 000 м.е.) и растущего количества каротинов от 12 до 49 мг/кг (группы I—IV), а также препарата Polfasol AD₃, соответствующего количеству витамина А от 6000 на 18 000 м.е./кг (группы Va—Vc). Применение этих смесей вызвало непропорциональные к дозам каротинов или вит. А колебания их концентрации в сыворотке крови. Не наблюдали закономерностей разниц в степени кумуляции вит. А в печени по мере увеличения уровня каротинов или вит. А в смесях.

The examinations were carried out for 42 days on 32 young geese divided into 8 groups at random and fed mash containing the standard content of vit. A (10 000 IU) and an increasing quantity of carotins, i.e. from 12 to 49 mg/kg (groups I—IV), and the preparation Polfasol AD₃ corresponding to 6000—18 000 IU of vit. A (groups Va—Vc). The use of the mashes brought about a changeable concentration of carotins and vit. A independently on their level in feed. There was not any regularity regarding vit. A cumulation in the liver along with an increase of carotins or vit. A in mash.
