China) The hilly-gully loess area is composed mainly of the fifth sub-region

involving parts of the second

third

and fourth sub-regions of the Loess Plateau.The major ecological environment problems in the region are short of rain

extremely dry

vast hilly gully area and intense soil and water erosion

which directly lead to the low quality of the local environment.Loss of soil and water

drought

low productivity and poverty are the prominent ecological

social and economic problems.We selected Dongshan village as a demonstration site

which is located in the Zhongshan river basin in the third sub-region of loess hilly-gully region.In addition to soil erosion control

rainwater harvesting and water saving irrigation techniques were deployed on the site as well.Meanwhile

many measures including cultivating and developing the featuring produces like grape

promoting water-saving agriculture

decreasing application amount of chemical fertilizers and pesticides were carried out to reduce non-point source pollution.We established a comprehensive monitoring index

and at the same time

set up a special monitoring and evaluating index system for demonstration benefit using analytic hierarchy process method based on field observation and interactive interview.
