The contribution was about - 1.3% , in which the primary, secondary and tertiary industries, contributed 2.11% , 0.50% and - 1.56% separately. Secondly, the benefits of ecological water in Shanxi were analyzed from the perspective of forest ecosystems. It was calculated that the service function value of forest ecosystems in 2003 and 2010 was 97.408 billion and 100.021 billion yuan, and the corresponding water consumption is 310 million and 340 million m3 . Aimed at the pollution and waste problems in production and ecological water allocation in Shanxi Province, countermeasures such as water saving, water pollution control and prevention, ecological water protection etc. are put forward.
