Dostopnost urbanega gozda in drugih zelenih površin v Mestni občini Ljubljana

Jerman, Jan (author), Nastran, Mojca (mentor)

Gozdovi in druge zelene površine opravljajo različne ekosistemske storitve in imajo na ljudi ter okolje različne blagodejne učinke, ki so tudi znanstveno priznani, vendar samo prisotnost zelenih površin na nekem območju ne dosega nujno zaželenih učinkov. Pravilo 3-30-300 je noviteta, ki združuje tri kazalnike »zelenosti« mest in ima potencial poenostaviti vrednotenje zelenih površin med načrtovalci, raziskovalci ter v širši javnosti. V magistrski nalogi smo kriterije pravila 3-30-300 s programskim orodjem ArcGIS Pro 3.0.1 analizirali na območju Mestne občine Ljubljana znotraj avtocestnega obroča, ki smo ga razdelili po mejah četrtnih skupnosti. 23 % celotne površine je zastrte z drevesnimi krošnjami. 63 % pozidanih površin dosega dostopnost v razdalji 300 m ali manj do zelenih površin v velikosti 1 ha ali več. 66 % zgradb na območju dosega vidnost vsaj treh odraslih dreves. Med zastrtostjo s krošnjami ter dostopnostjo je značilna pozitivna srednje močna korelacija (Pearsonov r (10) = 0,567, p < 0.050). Načrtovanje večjih zelenih površin z več odraslimi drevesi in boljšimi povezavami bi v prihodnosti lahko izboljšalo urbani ekosistem Ljubljane. Modeliranje pravila 3-30-300 je pionirska raziskava, ki lahko pomaga identificirati mestne predele, kamor je potrebno usmeriti več pozornosti pri načrtovanju zelene infrastrukture.

• Title: Accessibility of urban forests and other green spaces in the City of Ljubljana

Abstract

Forests and other green spaces provide various ecosystem services and have numerous scientifically recognized beneficial effects on people and the environment. However the mere presence of green spaces in an area does not necessarily produce the desired effects. The 3-30-300 rule is a novelty that combines three indicators of "greenness" of cities and has the potential to simplify the evaluation of green spaces among planners, researchers and the general public. In this master thesis, we analyzed the criteria of rule 3-30-300 using ArcGIS Pro 3.0.1. software for the Municipality of Ljubljana within the highway ring, divided into neighborhood communities. 23 % of the total area is covered by tree canopy. 63 % of built-up areas achieve accessibility within a distance of 300 m or less to green areas of 1 ha or more. 66 % of buildings in the area achieve visibility of at least 3 adult trees. There is a positive medium strong correlation between canopy cover and accessibility (Pearson's r (10) = 0,567, p < 0.050). Planning larger green spaces with more adult trees and better connections could improve Ljubljana's urban ecosystem in the future. Modeling the 3-30-300 rule is pioneering research that can help identify urban areas where more attention needs to be focused on green infrastructure planning.
