The study brings forward the basic conception of spatial information system for Chinese terrestrial ecosystem.Based on reviews of recent spatialization technology research of meteorology and climate information at home and abroad,we appraised virtue of methods in existence and discussed the model of spatial distribution of meteorology and climate information.Meanwhile,we summarized our preliminary achievement and set forth prospective applications.The developments of ecological,resources and environmental sciences imperiously call for spatia-lization technology research and data product exploitation of Chinese terrestrial eco-information.However,establishing a favorable spatial database of terrestrial eco-information which provides fine spatial-temporal resolution fitting in with diverse disciplines requirements demands long-ter-m study and disciplinary cooperation;simultaneously,it needs a lot of social funds devotion.
