The historical information could be managed by TGIS which has not been applied in the forest resource management. The Spatio-temporal data model is the core of TGIS. By referencing from several existing Spatio-temporal Data Models and analyzing the characteristics of the forest resources data, this paper proposes a new Spatio-temporal Data Model of forest resource named "multi base states model based on feature and event". It is proven efficient in managing and retrieving the forest historical information.
Since continuously, the researches on the relation between the land cover change and the climate change were in the
way of statistics and data comparing. This article has made the attempt to discover the relation in the way of map
contrast. Based on the modis EVI data, the article created land cover maps and land cover change map. Compared with
the land cover change map, the temperature change map shows the similar data distribution characteristics. On the other
hand, the changes of the humidity and precipitation do not show the similar distribution pattern through the visual
Recently, "Global Change and Terrestrial Ecosystem (GCTE)" and "Land-Use and Land-Cover Change (LUCC)" have become the core project and the important direction of the global change research.. The land cover is closely related to the climate and they mutually affect each other. The paper created Zhejiang land cover change map based on MODIS Enhanced Vegetation Index (EVI) products and climate change maps. A study of the relationship between the land cover change and the climate change was conducted on the maps. The conclusion was the land cover change has the relation with the local temperature change in the certain degree, does not have the relation with the precipitation change and the humidity change.
