چکیده

Urban stream ecosystems have often been seen as channels of water flow rather than as the valuable parts of an urban green space system providing ecosystem services. The study seeks to address the importance of urban stream ecosystems from the perspective of urban ecology, human health and social well-being in the context of urban planning The case study area is the paveh stream ecosystem in the City of paveh, western iran. The data from the case study area were gathered from questionnaire, existing scientific and library studies and by conducting interviews with residents and authorities and. Once the importance of the biodiversity of the stream had been studied based on the existing ecological data, the social importance of the stream and the linkages between human health, social well-being and the biodiversity of the stream ecosystem were addressed. Urban stream ecosystems can be rich in biodiversity and function as ecological movement corridors for species .Urban stream corridors can thus be an important part of the urban green infrastructure .also we can make the weather fine ,extend green space ,prepare peaceful environment for residents and bring the countryside effects of nature into cities through improvement of stream landscape .treatment of stream channels in construction projects often decrease species richness and destroy important streamside biotopes. In general, aquatic natural elements, such as small urban streams, can potentially to increase the ecological, social and health values of the area. An urban stream can function as an important recreational element within the local green space network. The social and health values of stream ecosystems may decrease if the stream sides are dirty and stream surroundings are regarded as unsafe.
