Ecological Comprehensive Harnessing Technology Of Small Watershed And Its Application In Kecheng District

Traditional small watershed management mainly focused on the flood control and conservation of water and soil.As our government attaches more importance to ecological construction,people have stronger appeals for ecology and culture,thus,ecological comprehensive governing technology of small watershed becomes a new trend of watershed management researches.The ecological small watershed management includes flood controls,water and soil conservation,aquatic ecosystems,landscaping,cleaning,management and many other aspects.Meanwhile,researchers have carried out a variety of practices,and got some successful cases.The different climate and environment background of small watershed make huge differences in their management.Ecological comprehensive management technology of small watershed combines ecological river management,river basin flood control,water purification,and some related technologies and measures.Above all,small watershed flood control is still the most fundamental aspect.The flood control of the small watershed consists of the dam flood control,the bank protection,the reservoirs regulating,flood monitoring,flood warning and other aspects.The small watershed management,which combines with engineering measures and management measures,makes flood protection and ecology in harmony.Water purification is the key of small watershed management,which includes water weir precipitation,water aquatic purification,artificial wetland water purification,oxygen aeration,drainage and fish purification etc.Combining physical and biological methods,it effectively gets command of point source pollution and surface source pollution,achieves water purification.Ecological landscape management is promotion of the small watershed management.Landscape barrages,waterfront plants,slope vegetation,promenade roads,landscape architecture and artificial wetlands etc.,all those above mentioned make contribution to the beauty of the watersheds.The Shiliang and the Miaoyuan streams in the Kecheng district were practiced based on the model of ecological management.After ecological management,these two streams' ecological management achieved a significant improvement in water quality and ecology.The culture and landscape sets off each other.At the same time,the around tourism economy has improved significantly.
