Analýza faktorů ovlivňujících efektivitu údržby okrasných porostů a parkových ploch při využití malé mechanizace
Mašán, Vladimír
The thesis titled Analysis of factors affecting the efficiency of the maintenance of ornamental vegetation and park areas using small machinery is addressing the issue of evaluation of effects of the factors which determine the performance of deployed equipment. In evaluating the performance of cutting machines, bush cutters, and hedge trimmers we have considered the effects of terrain segmentation and steepness in the locality, the character, plant species, and size parameters of the growths as well as the technical condition and design of machinery. The processed results then became the basis for the calculation of coefficients expressing the effect of each monitored factor on the performance of a given type of machine. Developed methods for 5-level evaluation of growths represent an original way of assessment of diverse factors on the performance of the machines by quantifying them. The proposed coefficients are clearly grouped so as their use under normal conditions of green areas maintenance is simple and practical. These coefficients are developed for the use of lawn tractors, riders, hand held mowers, hedge trimmers, hedge trimmer attachments, and brush cutters, and have been tested in practice. The identified and verified coefficients permit to evaluate the effects of selected factors under real-area conditions and determine the actually achieved performance. In the framework of the management of green areas maintenance their use is appropriate for the correction of performance of used machinery for more precise economic calculation of prices of maintenance works and deployment of equipment and personnel. The results of the work are also useful in garden, park, and landscape design and implementation where they can define the spatial distribution of vegetation elements with respect to the effective movement of machinery during maintenance.
