This study used Normalized Difference Vegetation Index (NDVI) timeseries derived from SPOT Vegetation and Proba-V images from 1999 to 2014. The onset of the growing season, end of the season, maximum NDVI observed during the growing season were determined using TIMESAT program. Results of the study shows that satellite data can be used in a variety of ways in research of phenology of broadleaved forests in Poland. More studies on forest phenology metrics and its relations to meteorological observations in Poland will help to understand the responses of temperate forest phenology to climate changes.<\/p>\r\n\r\n\r\n\r\n<p><strong>Key words: <\/strong>growing season, NDVI, forest monitoring, Mann-Kendall test, satellite images<\/p>\r\n\r\n\r\n\r\n<p><strong>Zalecany spos\u00f3b cytowania: <\/strong>Bartold M., 2018, Wyznaczanie pocz\u0105tku i ko\u0144ca okresu wegetacyjnego las\u00f3w li\u015bciastych w Polsce na podstawie wieloletnich obserwacji satelitarnych SPOT Vegetation i Proba-V, <em>Prace i Studia Geograficzne<\/em>, 63.3, Wydzia\u0142 Geografii i Studi\u00f3w Regionalnych Uniwersytetu Warszawskiego, Warszawa, 7-31.<\/p>\r\n\r\n\r\n\r\n<p class=\"has-small-font-size\">Wp\u0142yn\u0119\u0142o: 18.04.2018<br \/>Zaakceptowano: 15.09.2018<\/p>\r\n\r\n\r\n\r\n<p><a href=\"https:\/\/pisg.wgsr.uw.edu.pl\/?attachment_id=3762\">Pobierz ca\u0142y tekst w pdf\u00a0\/\u00a0Get full text (pdf format)<\/a><\/p>\r\n","protected":false},"excerpt":{"rendered":"<p>Wyznaczanie pocz\u0105tku i ko\u0144ca okresu wegetacyjnego las\u00f3w li\u015bciastych w Polsce na podstawie wieloletnich obserwacji satelitarnych SPOT Vegetation i Proba-V Determining the onset and the end of the growing season of the broad-leaved forests over Poland using long-term SPOT Vegetation and Proba-V satellite observations Maciej BARTOLD Uniwersytet Warszawski Wydzia\u0142 Geografii i Studi\u00f3w Regionalnyche-mail: maksb1983@gmail.com Zarys tre\u015bci: [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[13,21,341],"tags":[1059,1213,1569,1713,1793,1853,2291,2585,2947],"class_list":["post-762","post","type-post","status-publish","format-standard","hentry","category-artykul","category-bartold-maciej","category-t-63-z-3","tag-forest-monitoring","tag-growing-season","tag-mann-kendall-test","tag-monitoring-lasow","tag-ndvi","tag-okres-wegetacyjny","tag-satellite-images","tag-test-manna-kendalla","tag-zdjecia-satelitarne"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>T. 63.3, ss. 7-31<\/title>\n<meta name=\"description\" content=\"W artykule przedstawiono wyniki bada\u0144 zmienno\u015bci czasowej fenologii las\u00f3w li\u015bciastych w Polsce na podstawie obserwacji satelitarnych.
