Urban forest research based on regression tree techniques and ASTER imagery

Abstract: Urban forest was of great interest to a variety of scientific and urban planning applications. This paper presented the process and results of analysis using remote sensing imagery in this area. There were mainly two key steps in the analysis: the first was to analyze urban forest abundance utilizing regression tree techniques and advanced spaceborne thermal emission and reflection radiometer(ASTER) images; the second was to analyze the ecological benefits of urban forest using CITYgreen model. The analysis of urban forest abundance was accomplished implementing classification models,which were based on relationships between urban forest abundance and the spectrum on ASTER imagery,and were generated using regression tree techniques. Subsequently,the calculation of forest coverage,carbon storage and the amount of air pollutants removal about urban forest was carried out introducing CITYgreen model. According to the analysis,the total area in Tongzhou District was about 11.62 km2; the forest coverage was about 7.6%; the carbon storage and the amount of air pollutants removal amounted to 123 589 t and 267.1 t·a-1 respectively. At the end,the advantages and disadvantages,as well as some of the conceivable improvements of this strategy were discussed.
