| Abstract: | The dynamical monitoring of the water and soil conservation in Zhangpu County coastal shelterbelt, Fujian Province was realized,with the help of the United States USLE soil erosion model and the effective protection of coastal shelterbelt were appraised in accordance with the loss of organic matter in economic losses. The results showed that the coastal shelterbelt can markedly improve benefits of soil and water conservation, the economic losses declined. |
