Identify the Characteristics of the Urban Forest for Improvement of Environmental Quality in the City of Surabaya with Canopy Structure, Interception, Throughfall, and Stemflow

Khambali .


Increasingly dense urban activity indirectly cause environmental degradation in urban areas, especially in the city of Surabaya. Characteristics of a good urban forest in improving the environmental quality in the city of Surabaya can be seen to from  canopy structure, interception, throughfall, and stemflow. The aim of this study was to determine the characteristics of the urban forest as environmental quality improvement planning in the city of Surabaya in homogeneous and heterogeneous forests for canopy structure, interception, throughfall, and stemflow. This research method uses a simple regression to find the value of determination or R2. The results show the identification of the characteristics of the urban forest in the city of Surabaya, is; 1) the structure of the canopy can be seen from the value of the index on the density of the canopy of each tree, tamarind at 0.16, mahogany at 0.13, angsana at 0.07, landi acid at 0.16, and tamarind in heterogeneous forest at 0.16 , 2) interception of rainfall indicated by the R2 value of 0.92 on a tamarind, mahogany at 0.9, angsana at 0.88, landi acid at 0.979, and 0.936 for the heterogeneous forests, 3) throughfall in homogeneous forest trees tamarind at 4.13 mm, mahogany at       4.45 mm, angsana at 3.14 mm, and landi acid at 2.99 mm, and 4) stemflow in the forest is homogeneous tamarind at 4.35 mm, mahogany at 3.61 mm, angsana at 5.34 mm, landi acid at 2 mm, and heterogeneous forest (tamarind) at  3.35 mm
