Data from meteorological observations or posts operated over long time, measurement and calculation of NPP (net primary production) and biomass of biological community, and analysis of soil organic matter content show that the artificial alder and cypress mixed forest has outstanding eco-environmental effect: adjusting local climate, raising soil fertility, alleviating menace of drought, and raising NPP and biomass of biological community. It is very beneficial for improving ecological environment to afforest artificial alder and cypress mixed forest in populous Hilly Area of Central Sichuan Basin, China.

Coastal subsidence damages infrastructures and exacerbates the effect of the sea-level rise at regional scale. Although it is a well-known process, there is still much more to be improved on the monitoring, mapping and modeling of ground movements, as well as the understanding of controlling mechanisms. The International Geoscience Programme recently approved an international project(IGCP 663) aiming to bring together worldwide researchers to share expertise on subsidence processes typically occurring in coastal areas and cities, including basic research, monitoring and observation, modelling and management. In this paper, we provide the research communities and potential stakeholders with the basic information to join the participating teams in developing this project. Specifically, major advances on coastal subsidence studies and information on well-known and new case studies of land subsidence in China, Italy, The Netherlands, Indonesia, Vietnam and Thailand are highlighted and summarized. Meanwhile, the networking, dissemination, annual meeting and field trip are briefly introduced.展开更多

For instance, China is estimated to take 48% of the world potential for CDM project activities. In reality, however, the share by China over the CDM projects registered and CDM projects in the pipeline is less than 10% as of Auguest 2005. This paper will examine the reasons behind, as reflected in China's CDM policies. Further investigation will be made into the use of these policies to boost the country's sustainable development, the sustainable development implications and effects of these policies. In addition, it is noted that incompatibility of some other Chinese laws and policies can be responsible for the low level and slow pace of CDM implementation in China and some suggestions are offered for promoting CDM project activities in China. There also exist barriers at the international level that impedes implementation of CDM project activities. A conclusion is drawn that CDM policies in a developing country like China aim mainly at promotion of sustainable development and to a lesser extent the generation of CERs.展开更多
