Monitoring Index System of Water Environment of Ecologic and Clean-Type Small Watersheds

It establishes Beijing ecologic and clean-type small watersheds monitoring index system by taking an ecologic and clean-type small watershed as an object of study. The system includes 3 components: component 1 includes all together 17 indexes of intensity of soil erosion, living sewage treatment of villages and integrity of river biota; component 2 includes status of soil and water loss and area-source pollution, status of point-source pollution and status of rivers’ health; component 3 is the top index for evaluating the status of water ecologic environment quality of an ecologic and clean-type small watershed through an integrated analysis of the indexes of components 1 and 2. It hopes that the established system can provide basic data and decision-making basis for widely developed the building of ecologic and clean-type small watersheds and play a certain guiding function for protection and rehabilitation of small watershed ecosystem.
