The Commission for Integrated Survey of Natural Resources (CISNAR) has a role to play in land use and land cover change research. The many expeditionary and cartographic activities it carries out would be an excellent source for the development of a contemporary land cover database for the nation. Institute officials say it will be the database center for land resources in the national global change program. CISNAR already houses World Data Center-D for Renewable Resources and Environment and the Integrated Research Center for Natural Resources and Agricultural Development (a joint database project with the Ministry of Agriculture) and has regional and national databases for resources, ecology, and the environment. Additionally, CISNAR is the designated host of the CERN Synthesis Center, where synthesis and analysis of CERN-generated data will be conducted. Clearly, CISNAR has an important role to play and it is hoped that it will receive the extensive training, expertise, and appropriate equipment that will be required to realize this role successfully.
Through CISNAR, CAS has produced a very impressive compendium of natural resources that indicates a kind of database management (Natural Resources Study Committee 1990). A little historical analysis is visible here in the way of dendrochronology, but no evidence of predictive modeling activities.
Feng Zongwei and Zhuang Yahui at RCEES are carrying out a large-scale, collaborative forest ecology project with the objective of providing specific data on China's forest ecology for input to global change studies. Methodology includes soils and plant classification and mapping, experimental studies of material and energy flows, measurements of atmospheric gas concentrations (CO2, NOx, SO2, and O3), and comparison of differences between urban Beijing atmosphere and nearby mountain atmosphere. Comparisons will be made in different seasons, trends will be monitored for 5 years, and some modeling will be included. The mountain area studies will be conducted at the CAS Beijing Forest Ecosystem Station, which is located about 2 hours west of Beijing. The cost of the project is 1.8 million yuan, and funding is from the State Science and Technology Commission and NSFC.
In Nanjing, a few institutes are or could be contributing to land cover change research. At the CAS Nanjing Institute of Geography and Limnology, considerable historical analysis could be relevant. At the Department of Geo and Ocean Sciences at Nanjing University, high-quality historical analysis and qualitative land cover change projections are being developed. The projections are done mainly through land use change, and are coupled with hydrological and sedimento
