Due to the global changing and its impacts, the coast zone is one of the most vulnerable area in the future. To make a further understanding to the coast vulnerability and make measures for avoiding the adverse impacts of global changing, the IPCC stimulated the countries with coast area to assess the vulnerability of their coast zone. Based on the related studies, the coastal vulnerability concept and the vulnerability assessments is discussed in this paper. Following the IPCC CZMS (1992), the coastal vulnerability is defined as "The degree of incapability to cope with the consequences of climate change and accelerated sea-level rise". Because coast zone located the transitional area between land and sea and is the area with the densest population, the coastal zones are susceptible to global change. To maintain the ability of physical resilience and realize the sustainable development management is the key to solve the problem. Recently, to understand the vulnerability degree and study the science management. The vulnerability assessment have been done in lots of countries and regions according to the common method of IPCC. This paper also describes the common method of vulnerability assessment and the main results of present coast vulnerability assessment. At the same time, the further study content are put forward, that is the accurate modeling study on coast response to global change, the methods of integrated coast vulnerability assessment, dynamic vulnerability assessment methods and more extensive cooperation in coast vulnerability study.

Full and Open" sharing of the full suite of federal-funded global data sets for all global change researchers is a fundamental objectives of US Global Change Data Management Policy. This concept has been fostered by many international organizations for many years, but finally implemented in the United States in last ten years. US Government has played a leading role in achieving the full and open sharing of scientific data and information, because the data- or information-based products are associated with what economists call "public goods" and also with "externalities". US Government has enforced this policy by two steps. First, form a national level "Distributed Active Archive Centers-DAACs"; the selected centers represent a wide range of Earth scientific disciplines. The responsibility of DAACs are processing, archiving, and distributing EOS data and related data, and providing a full range of user support. Second, under the framework of US Global Change Research Program (USGCRP), broaden the DAACs to Global Change Data and Information System (GCDIS). The GCDIS will provide the infrastructure of the global change data and information management program. This is a priority-driven system composed of individual agency systems made interoperable by the use of common standards and approaches, technology sharing, and data policy coordination. The GCDIS functions include setting priorities for individual data and information sets, identifying and/or developing those sets, and incorporating them and the necessary related services in GCDIS. The success of GCDIS may indicate that Central Government should play a more active and leading role in order to establish a cost-effective global change data and information system in China.

In recent years, great achievements have been made in the mechanism of early-stage coalification and diagensis of organic matter as the results of the exploration and studies on the immature-low mature oils and biogenic gas. In addition, the results of early-stage coalification and diagensis of organic matter are also an important factor for correctly identifying the macerals genesis and its matured process. The research advances are as follows: (1) Advances in coal macerals and lithotypes origin, especilly the results form microscope observation of present peat. Through analysing petrologic and geochemical characteristics of varied salt and fresh water bogs; temperate zone, subtropical zone and the tropics bogs; herbaceous and woody plants peat and the peats formed varied sedimentary environments; Comparing similarities and differences of plant tissue and organ among present bogs surface layer, buried peat and plant relics in coal ball. Coal geologist have studied the degradation process of plant, and present possible cause of coal macerals formation from some plant tissue and organ during biochemical coalification and coalification. (2) Geochemical advances in diagensis of sediementary organic matter. Through the analysis methods such as pyrolysis, thermal simulation experiment, infrared spectroscopic analysis, element analysis, 13CNMR, isotope assaying, GC-MS and so on, scientists have been studing organic molecules, such as humus, humic acid, fat acid, lignin etc , transition and mechanism during diagensis of sedimentary organic matter, and getting clearer understanding of kerogen chemical structure and mature process. (3) Through artificial coalification of peat and the thermal simulation of present plant, analysing the physical-chemical transition process of sedimentary organic matter during early-stage coalification. (4) There are two aspects of influence of bacteria on coal formation during early-stage coalification. ① A lot of microorganis were identified with investigation on peat bogs, and there are different microbiota from upper to bottom of peat bogs, and microorganis amount is also different. The influence of different bogs types and sedimentary environment on bacteria growth are also researched. The results show that microorganis play an important role on the plant relics degradation and transition of the bogs. ② Through analysing biomarker and petrologic characteristics, researching microorganis contribution and bacteria degradation degree on organic matter in sediment rocks. Nevertheless there are also a lot of question in early-stage coalification: Firstly, the origin of coal maceral and transition process are not completely be understood. As we know, it is qualitative change in geochemistry from plant relics to hard coal. The components and nature of peat and brown coal are very complicated, but those of hard coal are relatively simple, so there must bea lot of gas and liquid matter from the transition process, for example, ga

The forming and evolution of Qinghai Tibet plateau is an important research field, which is concerned by geologists all over the world and has very great effect on topography, rive systems, monsoon in Asia and the changes of climate and oceanic chemical composition in the world. However, because of lacking quantitative researches, some of key problems haven't been solved. The appearance of mass balance offers a new method to solve these problems. In this article, the principle of mass balance is introduced, then application is illustrated with examples of basins in Tibet plateau, East China, surrounding Indo China and the Indian Plate. Some problems of using the method are discussed in detail, which would be the main research points in the future.

Spatial interpolation can be classified in accordance with their basic hypotheses and mathematical natures as: geometric method, statistical method, geostatistical method, stochastic simulation method, physical model simulation method and combined method. The application areas, special algorithm, advantages and disadvantages of each interpolation method are introduced and compared in the paper. The comparison shows that there is no absolutely optimal spatial interpolation method; there is only relatively optimal interpolation method in special situation. Hence, the best spatial interpolation method should be selected in accordance with the qualitative analysis of the data, exploratory spatial data analysis and repeated experiments. In addition, the result of spatial interpolation should be strictly examined for its validity. Development of general software for spatial interpolation and strengthening the basic theory research are key issues in the future.

Aerobic soil in terrestrial ecosystem is the greatest methane sink, it contributes significantly to the atmospheric methane budget. It is important to study the sink strength and the influence factors for the purpose of balancing the methane in atmosphere and taking measures for increasing the uptake capability. The paper reviews the impact of land use change, soil temperature, soil pH, and agricultural practice such as irrigation, fertilizer application on soil consumption of atmospheric methane. Results indicate that atmospheric methane consumption is especially sensitive to anthropogenic disturbances, which typically decrease the consumption capacity.
