Pedogenetski dejavniki in njihova vloga pri nastajanju biotske pestrosti = Factors of soil formation and their role at biodiversity formationRepe, Blaž, 1972-Vse, kar vpliva na nastanek, razvoj in lastnosti prsti ter istočasno na njihovo razširjenost, lahko strnemo pod pojmom pedogenetski (tlotvorni) dejavniki. Z vidika sistemske teorije so to dejavniki ... okolja oz. geografskega okolja, pokrajine, ki delujejo na proučevani podsistem, to je na prst. Do podobnih zaključkov se je dokopal že Dokučajev koncem 19. stoletja, temelje postavi Jenny leta 1941, za slovenske razmere pa je pedogenetske dejavnike v obliki formule zapisal Stritar. Rastlinstvo je neposredno življenjsko odvisno od prstene odeje. Prav zato se v prilagoditvah rastlin, še mnogo bolj pa v rastlinskih združbah, zrcalijo lastnosti prsti in posredno tudi pedogenetski dejavniki. Poznavanje pedogenetskih dejavnikov nam pomaga razložiti in prepoznati rastiščne zahteve za različne oblike vegetacije. Obenem je mogoče pedogenetske dejavnike preslikati v rastiščne dejavnike, s katerimi opredeljujemo biotsko pestrost rastlinskega pokrova. Zveze smo iskali v Polhograjskem hribovju, zahodno od Ljubljane. Po pokrajinski, zlasti panoramski podobi je Polhograjsko hribovje izrazita gozdna pokrajina. Zelo skromen, le nekaj odstotni delež ravninskega in velika prevlada strmega sveta ne dovoljujeta obsežnejše in intenzivne kmetijske pridelave. Če k temu dodamo še prevlado silikatnih kamnin s (pre)kislo in siromašno prstjo na eni strani ter plitvimi prstmi na karbonatni matični podlagi ne preseneča dejstvo, da je gozd dejansko dominantna pokrajinska poteza, v katerem dominira bukev (Fagus sylvatica).Source: Strategija varovanja tal v Sloveniji : zbornik referatov Konference ob svetovnem dnevu tal 5. decembra 2007 (Str. 173-187)Type of material - conference contribution ; adult, seriousPublish date - 2007Language - slovenianCOBISS.SI-ID - 35766882
