Abstract

In past decades, ecological services and functions of alpine grassland in the Three-River Headwater Region (TRHR), Qinghai-Tibetan Plateau, have been severely degraded due to overgrazing and overuse of yak dung as a fuel. Therefore, the eco-migration project has been implemented by the national government for improving eco-environmental quality in this region. This paper examines the carbon cycle change from clean energy use of households and assesses its influence on the local grassland ecosystem. Based on the data of household fuels from questionnaire surveys and local statistical yearbooks, we have calculated carbon emission and the ecological benefits by using clean energies. The results showed that total carbon in the process from Net Primary Productivity (NPP) of the ecosystem to dung fuel decreases sharply, and carbon emission from dung is approximate 6% of ecosystem NPP. Reducing the use of yak dung as a fuel has no significant influence on carbon emission, but improves the ecological benefits of the grassland ecosystem, because it is a very important part of the ecosystem carbon cycle. With the most abundant solar energy resources in China, the region should make full use of its advantage for improving ecosystem service values of alpine grassland by making more dung returns to grassland. In conclusion, a clean energy policy (CEP) can effectively improve the ecological services and functions of alpine grassland in the TRHR. View Full-Text
