The complex of sanitary and health-improving measures in the forest is considered, which includes harvesting of waste wood with simultaneous quantitative and qualitative assessment of characteristics of waste wood in the whole forest area with a given accuracy in real time in the process of harvesting. The variant of waste wood harvesting with wood processing for wood chips in the forest is considered. The main machines carrying out harvesting on technological strips are specified, in particular mobile winch and chipper. With the use of natural data, mathematical model studies of estimation of the volume and quality of waste wood by simulation modelling methods based on the method of linear intersections have been carried out. It was found that at the volume of waste wood from 5 to 50 m3/ha the required total length of technological strips for the accuracy indicator P = 20 % is in the range from 500 to 6000 metres. It was determined that the errors between the true values of the waste wood volume and its estimates did not exceed 11,3 % in absolute value. It was found that the time to record and estimate the volume of waste wood decreases with increasing volume of waste wood in the plot. It was found that the main factors are the length of technological strips and the volume of waste wood on the plot. It was shown that the productivity of waste wood volume counting, and estimation increases as the volume of waste wood on the plot increases.

Рассмотрен комплекс санитарно-оздоровительных мероприятий в лесу, включающий в себя уборку древесины отпада с одновременной количественной и качественной оценкой характеристик древесины отпада на всем участке леса с заданной точностью в реальном масштабе времени в процессе уборки. Рассмотрен вариант уборки отпада с переработкой древесины на щепу в лесу. Указаны основные машины, осуществляющие уборку по технологическим полосам, в частности мобильная лебедка и рубительная машина. С использованием натурных данных, на математической модели проведены исследования оценки объема и качества древесины отпада методами имитационного моделирования на основе метода линейных пересечений. Установлено, что при объеме древесины отпада от 5 до 50 м3/га потребная общая длина технологических полос для показателя точности P = 20 % находится в пределах от 500 до 6000 м. Определено, что ошибки между истинными значениями объема отпада и его оценками не превысили по абсолютной величине 11,3 %. Установлено, что время учета и оценки объема древесины отпада уменьшается с увеличением объема древесины отпада на участке. Установлено, что основными факторами являются длина технологических полос и объем древесины отпада на участке. Показано, что производительность на учете и оценке объема древесины отпада увеличивается с увеличением объема древесины отпада на участке.
