Four urban greenbelt types including roadside greenbelt, resident-area greenbelt, landscape forest, and forest park, were simultaneously investigated in Shenzhen, China, in such measures as air temperature, air humidity, wind speed, air anion ratio, and inhalabal particle concentration, which were strongly related with pleasing feeling of human body. The results show that the average air temperature in both forest park and landscape forest is much closer to the pleasing feeling of human body temperature than that of the rest two greenbelts, where it is 1.782 ℃ and 0.837 ℃ in forest park as well as 3.084 ℃ and 2.140 ℃ in landscape forest less than that of roadside and resident-area greenbelts, respectively. In terms of mean air humidity, forest park and landscape forest are 3.034% and 7.563% higher than that of roadside greenbelt, and 1.205% and 5.734% higher than that of resident-area greenbelt, respectively, implying a sound humidity feeling of human comfort in the former two types. The air cleanness holds a descending rank as forest park, landscape forest, resident-area greenbelt, and roadside greenbelt, whereas the rank in inhalable particle concentration is completely reverse. In general, landscape forest and forest park that mainly consist of trees have a comparatively higher feeling of human comfort whereas roadside and resident-area greenbelts fluctuate irregularly to some extent for the measures studied. The four greenbelt types investigated could be summarized in human comfort as the following descending rank, forest park, landscape forest, resident-area greenbelt, and roadside greenbelt.
