Title: Presoja prostorskega stratificiranja za vzorčno ocenjevanje gozdnih zemljišč Authors: ID Hladnik, David (Author) Files: PDF - Presentation file, download (876,96 KB) MD5: C8ED84FFF35E7A36CD5ACCD783E1D7F0 PID: 20.500.12556/dirros/dba99df0-1cee-479c-9828-0ddd0b89605d   Language: Slovenian Typology: 1.01 - Original Scientific Article Organization: SciVie - Slovenian Forestry Institute Abstract: Za vzorčno ocenjevanje rabe gozdnih zemljišč in pokrovnosti ter njunih sprememb na Slovenskem predlagamo stratificiranje prostorskih podatkov na podlagi tipologije gozdnih rastišč. Na podlagi karte rabe zemljišč in tipologije gozdnih rastišč smo ocenili prostorska merila variabilnosti za krajinske kazalce in jih primerjali s stratificiranjem po statističnih regijah. Ker gozd po površini prevladuje v 10 od 12 statističnih regij, te ne predstavljajo izhodišča za oblikovanje stratumov, s katerimi bi pojasnjevali razlike v variabilnosti deležev rabe zemljišč. S statističnimi regijami smo pojasnili 21 % skupne variance za ocenjevanje deležev kmetijske rabe in 17 % variance za delež gozda. Z razvrščanjem kilometrskih kvadratov po tipologiji gozdnih rastiščnih tipov je bil pojasnjen večji del variabilnosti kot v prostorskem merilu statističnih regij, vendar na račun velikega števila skupin oziroma 29 stratumov. Velike razlike v krajinskih kazalcih za te skupine gozdov ponazarjajo, da je prostorsko merilo za oblikovanje stratumov manjše od regionalnega.

Title:	Evaluating spatial stratification for sampling forest cover data
Abstract:	Stratification based on Slovenian forest typology has been proposed for sampling forest land-use/ land-cover data and changes over time. Using land-use map and forest typology map we evaluated geographic scales of variance for landscape-level indices and compared stratification by administrative units and regions. As forest prevails in 10 out of 12 statistical regions in terms of its surface area, these regions cannot be effective stratification tool for sampling and mapping land-use. Statistical regions accounted for 21 percent of the total variance of percent agriculture and 17 percent of total variance in amount of forest. Through the classification of quadratic 1 square kilometre tiles according to the typology of forest site types, somewhat greater proportion of total variance has been explained by stratification than on the spatial scale of statistical regions, although on the account of the high number of groups (29 strata). The great differences in fragmentation indices for these forest groups illustrate that the spatial scale for the formation of strata is smaller than the regional one.
