Abstract (English):
Forma poperechnogo secheniya derev'ev v nasazhdeniyah yavlyaetsya vazhnym, no nedostatochno horosho izuchennym voprosom v oblasti izmeritel'nyh i lesouchetnyh rabot. Uproschenie formy poperechnogo secheniya do proekcii kruga ili ellipsa ne pozvolyaet povysit' tochnost' izmeritel'nyh rabot. Bolee detal'noe izuchenie samoy formy poperechnogo secheniya i faktorov, vliyayuschih na nee, pozvolit adaptirovat' metodiku izmereniya pod konkretnye usloviya proizrastaniya i povysit' tochnost' izmereniy. Osnovnoy cel'yu dannoy raboty yavlyaetsya izuchenie faktorov,vliyayuschih na formu poperechnogo secheniya otdel'nyh derev'ev i ustanovlenie stepeni etogo vliyaniya. Dlya dostizheniya postavlennoy celi neobhodimo opredelit' formu secheniya u kazhdogo issleduemogo dereva, vypolnit' korrelyacionnyy analiz svyazey mezhdu formoy stvola i taksacionnymi pokazatelyami. Posle etogo provoditsya regressionnyy analiz dlya naibolee vyrazhennyh svyazey i sostavlyayutsya uravneniya. Issledovanie provodilos' v 2015-2017 godah na territorii treh rayonov Krasnoyarskogo kraya: zapovednik «Stolby», uchebno-opytnyy leshoz SibGU i Mininskoe lesnichestvo. V hode issledovaniya ustanovleno, chto tip landshafta okazyvaet vliyanie na chislo derev'ev razlichnoy formy poperechnogo secheniya. Chem bolee raznoobrazny usloviya proizrastaniya, tem bol'she stvolov nepravil'noy formy. Mezhdu procentom derev'ev razlichnoy formy i nekotorymi taksacionnymi pokazatelyami nablyudalas' znachimaya umerennaya svyaz'. Graficheskiy metod analiza regressionnyh svyazey pozvolil ustanovit' znachitel'noe umen'shenie procenta derev'ev nepravil'noy formy s vozrastom, uvelicheniem srednego diametra, sredney vysoty v rayone zapovednika «Stolby» i s rostom polnoty v rayone «Karaul'naya». Regressionnyy analiz pozvolil poluchit' ryad dostovernyh i adekvatnyh uravneniy dlya prognozirovaniya procenta derev'ev nepravil'noy i okrugloy formy
