CO2 concentration in different communities in green lands had an obvious diurnal variation, chronically decreasing, and temperature influenced the lilac area and the grassland. Seasonally, CO2 was lowest in the larch green land （344.03 ±23.03 μmol/mol） and highest in the grassland （360.13 ± 22.43 μmol/mol）. The overall trend in CO2 concentration was autumn 〉 spring 〉 summer; temperature is the main factor controlling variation in CO2 concentrations during the growing season; the CO2 concentration at the larch, birch, lilac, and grassland types of sites was negatively correlated with land surface temperature and air temperature, and the CO2 concentration at the larch and birch sites was positively correlated with atmospheric pressure. Without any obvious annual change law, further study and observation are needed.展开更多

National Maritime Museum collects and displays maritime culture and civilization of China, it is a signifi cant cultural facility in New Binhai District of Tianjin. The museum shows us the splendid picture of yel ow terrestrial civilization and blue maritime civilization over the past 2,000 years in China. Landscape design outside the exhibition hall of the museum has the integration of culture and museum as the starting point, and makes brand-new explorations in landscape humanistic care and landscape designs of green buildings.展开更多
