It is concluded that: T he field experim en t and the fu ll2scale labo rato ry experim en ts are p referred; L andfo rm changes shall be as sm all as po ssib le and the mob ility of experim en tal devices is p referab le in the field study; T he rebu ilt landscape shou ld be sim ila r to the p ro to typ e and m eet the dem and of the p ract ica l eng ineering in the labo ra to ry study. F ina lly it is suggested tha t in the la test fu tu re, the ra infa ll sim u la t ion and runoff ob servation system su itab le fo r the u rban environm en ts shou ld be developed and the rain harvest experim en t fo r variou s typ ical u rban perviou s su rfaces shou ld be conducted.
