Karinių pratybų šaudymo metu keliamo triukšmo poveikio aplinkai įvertinimas / Estimation of noise effects of shootings during military training activitiesStaškutė, Jurgita 08 September 2009 (has links)
Triukšmo poveikis aplinkai buvo tirtas šaudant iš priešlėktuvinių pabūklų L70 ir RBS-70 netoli Juodkrantės esančioje teritorijoje. Nustatyta, kad priešlėktuvinės artilerijos pabūklo L70 keliamas triukšmas neviršija leistinas triukšmo normas gyvenamųjų ir poilsio namų teritorijose. Įvertinus turimus mokslinės literatūros šaltinius, triukšmo matavimo rezultatus bei vizualinių stebėjimų duomenis, nustatyta, kad šių pabūklų keliamas triukšmas nepaveiks paukščių migracijas. Taip pat RBS-70 ir L70 pabūklų keliamas triukšmas negali įtakoti paukščių būklės žiemavietėse ties Lietuvos Kuršių nerijos pajūrio krantais dėl per didelio atstumo ir garso išsisklaidymo. Remiantis literatūra, pratybų metu keliamas triukšmas galėtų turėti neigiamos įtakos netoli nuo šaudymo vietos perintiems paukščiams, bei Juodkrantės šiaurinėje pliažo teritorijoje esantiems poilsiautojams, todėl nerekomenduojama vykdyti pratybų paukščių perėjimo ir vasaros poilsio sezono metu. Nustatyta, kad iš priešlėktuvinio pabūklo RBS-70 keliamas mažesnis triukšmas nei iš L70, todėl šio pabūklo triukšmo poveikis aplinkos komponentams bus mažesnis. / The effect of noice to environment caused by shooting of antiaircraft cannons L70 and RBS-70 was investigated in an area located near village of Juodkrante. This study revealed that the level of noise which was caused by L70 is esunder limits of residential and recreation zones. According to results of research, scientific publications and data of visual observations, we found out that noise made of antiaircraft guns could not affect the migration of avifauna. Also it was established that noise made of L70 and RBS-70 could not have any negative influence to avifauna in places of hibernation which are located beside the coasts of Kursiu nerija. However, the boom produced during the military practice could have some negative effects to sitting birds near the training ground. Furthemore, it could cause some problems to holidaymakers situated on the north side of the beach of Juodkrante. Thus it is not recommended to do the military practice during the summer-season and breeding-time of aviflauna. Additionally, we ascertained that the level of noise caused by antiaircraft gun RBS-70 is lower in comparison to L70. Thus the negative influence of RBS-70 to environmental components could be lower than L70.
