- Abstract:
- In this paper, the benefits of soil and water conservation measures of Ankang, Shangluo and Hanzhong were analyzed based on the statistics and typical watershed survey data from 2007 to 2010, during which the method of contrastive analysis was used. The research areas, which lie in the southern Shaanxi Province, belong to the the water supply area of the middle-route of the South-to-North Water Diversion Project. The results showed that impound runoff and soil conservation increased apparently compared with former treatment, the ecological environment had been improved with the increase in vegetation coverage, the living standard of local people also increased. Effects of different measures on impound runoff were as follows: closing hillside > vegetable measures > slope harness measures > alternative energy measures > tillage measures;the order of the role of different measures on soil conservation are as the sequence of vegetable measures > closing hillside > slope harness measures > alternative energy measures > gully erosion control measures > tillage measures. This study can provide useful guidance for comprehensive harness of soil and water loss in similar water supply area.
