摘要：Tree architecture effect how rainwater is partitioned into canopy interception, throughfall and stemflow. The canopy shape and bark/leaf surface morphology affects their plants ability to intercept and redistribute rainwater. In this way, tree structure plays a role in soil and water conservation, especially in erosion runoff. This research was conducted for 32 rainfall events in Purwodadi, in January 2014-March 2015 during the rainy season. Stemflow, throughfall, and individual tree architectural characteristics and leaf morphology were measured for eight tree local species selected. This study aim is to predict the most appropriate tree species that is suitable on soil and water conservation. Study species included Sterculia cordata , Aleurites moluccanus , Buchanania arborescens , Calophyllum inophyllum , Dysoxylum gaudichaudianum , Peltophorum pterocarpum , Alstonia scholaris , and Pometia pinnata . The species which produced the greatest interception was Aleurites m o luccana with a value of 68.1% of rainfall. Special characteristics of the leaves (like fine hairs), globose stem and long, grooved bark, appear to causing increase relative interception of the rain water to be higher than other trees. Throughfall and stemflow for each species were closely related to rainfall amount but not related to rainfall intensity..
