With the rapid development of urbanization and the acceleration of the process of industrialization, environmental pollution is becoming more and more serious. Smoke, dust and dirt are major air pollutants. Urban scenic forestland has the ability to filter and absorb the smoke, dust, dirt and other air pollutants effectively. Dust detainment is an important service function of the ecology system in urban green space. This study makes dynamic evaluation and comparison on the dust detainment of Hangzhou urban forestland in different periods, which shows the value of the dust detainment in Hangzhou urban forestland during the period of the Ninth Five-year Plan, Tenth Five-year Plan and Eleventh Five-year Plan are 8.742 million yuan/a, 9.975 million yuan/a and 9.924 million yuan/a, respectively. The result shows an up trend from the Ninth Five-year Plan period to the Tenth Five-year Plan period, but a down trend from the Tenth Five-year Plan period to the Eleventh Five-year Plan period. Furthermore, in the list of the total value of the annual dust detainment for different community types, the top 3 are broad-leaved evergreen forest, evergreen deciduous broad-leaved mixed forest and deciduous broad-leaved forest, the last one is bamboo and broad-leaved mixed forest. And this result has a close relationship with the green space area and dust detainment ability of different community types.
