Plant Species Selection and Community Configuration for Residential Areas Based on the Digital Technology

Abstract

Sunshine is a key ecological factor for plant growth, development, reproduction and their community stability. The SOLWEIG model combined with ArcGIS and, AutoCAD software as a digital platform was used in this paper, and which focus on sunshine duration simulation by these digital technologies. Results show that the maximum sunshine duration is 10 hours, the minimum sunshine duration is 0 hours, and the average is about 4 hours in the sample points of the study area. The order from high to low is N>D>F>B>E>G>K>C>A>L>M (patches of planting area) in sunshine duration, the average highest value is 6 hours and the lowest is 1.6 hours for the 11 greening patches in this study. These results also indicate that the building height and layout is the major factor of influence in the change of sunshine hours when other parameters are stable. On this basis, the research combined with the standard system of sunshine requirements of landscape plants, an empirical analysis of plant selection and community configuration to show through a case of Tongxiang city in Zhejiang province, China. The value of this research is to provide a theoretical method for plant selection and community configuration in urban built-up areas.
