    The temporal variation of China’s farmland area and grain crop sown area sinces the year 1949 are studied comprehensively in this paper. Supported by the database of China’s national grain production, the author studies the temporal variation characteristics of China’s farmland area and grain crop sown area quantitatively in two aspects: temporal variation tendency and temporal variation mechanism. Based on the temporal variation regularity obtained above, China’s farmland area and grain crop sown area are predicted by “comprehensive dynamic prediction method” and “equal dimensional GM(1,1) dynamic prediction method”. The prediction result is that China’s farmland area will be 94 000 thousand hectares and China’s grain crop sown area will be 108000 thousand hectares by the year 2000.

    This article presents a review on the application of Artificial Intelligence (AI) and Expert System(ES) in Geo sciences. Although there has been much progress in Geo sciences, they still lack the right capabilities to establish information systems to solve Geo problems, and it is urgent to study and apply AI and ES technology in Geo models and Geo systems to solve complex problems in the real world. This article examines many Geo ES systems established by Geo scientists and computer scientists in recent years, and discusses them in many detail aspects, such as in methodology, technology, Object Oriented features and integration problems. Finally, This paper suggests that it is urgent to study geo information mechanism to apply Geo expert system, Artificial Neuron Network and Fuzzy theory, because they may play a central role in next generation Geo expert systems based on case reasoning provided by GIS spatial database. With the quick development of spatial information technology, there will be a overall fusion of RDBMS,RS,GIS, GPS, AI, ES and DSS. Those technologies will be integrated into Intelligent Spatial Decision Support System(I-SDSS), and gain more power to solve PRED problems.

    Beginning with such factors as social cultural background, social economic background, ecological and social psychological background which influence tourism bearing capacity, the article puts out the tourism bearing capacity index and its arithmetic model of operation and gives out a case of its application. The authors define the tourism environmental bearing capacity as the bearing intensity of tourism destination during a period which doesn’t do harm to the present and future people in its current state and which can be accepted by the residents. The bearing intensity of tourism destination mainly includes three sub class indexes: the tourist density, the tourism land use intensity and the tourism income value. To calculate the tourism Activity Intensity in a comprehensive indicator, the Tourism Bearing Capacity index is defined by the authors as a non—dimension value which can be an assessment indicator for sustainable tourism.
