The present invention relates to a water collecting basin, a water resisting element and a water resisting method thereof, and particularly to a water collecting basin used for water containing vessel, such as flower pot, to resist the leakage of stagnant water, a water resisting element and a water resisting method thereof. The main structure of the water collecting basin comprises a basin body and a water resisting element, in which the basin body has a water collecting tank for collecting excess water after watering and, the water resisting element is filled or placed in the water collecting tank, or the water resisting element is integrally combined with the basin body, which is adjacent to the bonsai flower pot for absorbing excess water and preventing the stagnant water from directly contacting with the outside environment. Thus, the present invention can not only prevent the insects from laying eggs and breeding in the stagnant water to reduce the infection source, but also avoid the spill of stagnant water to mess up the environment.本發明係有關於一種集水盆、隔水件及其隔水方法,尤指一種可用於如花盆之含水容器而具有阻隔積水外露之集水盆、隔水件及其隔水方法,集水盆主要構造係包含有一盆體及一隔水件。其中,盆體具有一集水槽,可用以收集澆花後之多餘積水,而隔水件則被填充或擺設於集水槽中,或者是隔水件與盆體結合成為一體,緊臨盆栽花盆,可用以吸收該多餘積水,並阻隔積水直接接觸外界環境,藉此不僅可預防蚊蟲在積水內產卵繁殖而降低傳染病源外,又可避免積水外溢而造成環境之髒亂者。21‧‧‧含水容器215‧‧‧排水孔23‧‧‧土壤30‧‧‧集水盆31‧‧‧盆體33‧‧‧集水槽35‧‧‧隔水件
