With continuous economic and social development, the demand for electricity is increasing and carbon dioxide emission is growing. Development of hydropower resources as a clean energy can ease our reliance on carbon energy and its consumption. This paper presents a case study of Linyi city of Shandong province to assess and demonstrate the low-carbon benefits produced by developing hydropower in the hilly areas of North China. Methods for the assessment were developed, and the development trend in this city was analyzed. The results show that in 2010, the hydropower output totaled to 59.46 million kW · h that created a revenue of 16. 76 million Yuan and a low-carbon benefit of 17. 95 million Yuan. This means a saving of standard coal of 22, 000 tons and a reduction in carbon dioxide emission of 72, 000 tons, and hence it demonstrates that the hydropower development in the city brings about a low-carbon benefit of nearly the same value. In Linyi, the low-carbon benefits keep increasing as its hydropower resources are further developed. This case study lends a theoretical and technical support to hydropower development in the northern hilly areas. © Copyright.

Ecosystems and their components provide a lot of benefits for the welfare of human beings. Coupled with increasing socioeconomic development, most of the rapidly developing and transitional countries and regions have been experiencing dramatic land use changes. This has resulted in a large amount of forestland, grassland, and wetland being occupied as residential and industrial land or reclaimed for arable land, which in turn results in a sharp deterioration of ecosystem services around the world. Shandong Province, an economically powerful province of China, was chosen as a case study in order to capture the impact of socioeconomic development on ecosystem services. By way of the study, land uses and their changes were categorized between 1980 and 2006, and the ecosystem services capital and changes of 111 counties of Shandong Province in different phases were evaluated, as well as the total ecosystem services capital, followed by the zoning of ecosystem services function region of Shandong Province. We found that the counties in mountainous areas and wetlands, where generally the prefectural-level cities are located with a rapid socioeco-nomic development, experienced a successive deterioration of ecosystem services especially during the 2000s. Finally, three conservation strategies for managing and improving ecosystem services were proposed and discussed with the aim of achieving coordinate and sustainable development of the socioeconomy, environment, and ecosystems not only in Shandong Province but also in other provinces of China, as well as in other developing and transitional countries and regions. © Springer Science+Business Media B.V. 2011.
