Nonpoint pollution control for rural areas of China with ecological engineering technologies

Abstract

Abstract: Nonpoint pollution from rural areas is the results of the ecosystem degradation,and ecological engineering technologies are good ways for the restoration of watershed and enhancing material cycling.There are two types of treatment strategies:to control the polluted runoff and to reduce the pollutants from the sources.Six control technologies are introduced and they are multipond systems,grassed filter trips,wetland systems,eco-agriculture,slope ecological engineering,ecological treatment of wastewater and soild waste.These technologies need to be combined systematically in order to form a watershed ecological engineering.In the control program,it is important to use countermeasure suitable to the local conditions.In addition,the input of sufficient investment,management and education is necessary.

Key words: Nonpoint pollution, Ecological engineering, Control, Technology
