Abstract: The paper aims to discuss the optimized space of landscape configuration and community air quality. Based on multi- technology integration module and landscape sampling, and evaluation and optimization methods, we studied the effects of multi-technology integration module on optimized space of landscape configuration and community air quality. The results showed that: there were significant differences of the △plant height and △trunk diameter between the chemical control plants (HGa, HIAA, RCC, RP) and CK; the promotion rate and inhibition rate of the tested varieties were within the best ratio range of field trials; and the richness of plant species, seasonal colors and spatial level in Blocknto were improved after optimizing; there were significant differences in Blocknto before and after optimizing, and the omprehensive evaluation results were improved by two grades. After optimizing, the air pollutants in Blocknto declined by a certain degree. There were extremely significant differences in the indexes of PM2.5, PM10, SO2 and AQI, and significant differences in CO, NO2.
