Study On The Spatial-temporal Patterns Of Eco-environment Geo-information Tupu In Fujian Provincn

Geo-information Tupu is an advanced researching field initiated by Academician Chen Shupeng who inducing, summarizing, abstracting and generalizing the complex geo-phenomena with a thought of Tupu, which has its preponderance in disclosing the intrinsic law of "patterns and processes" of the geo-phenomena. The objectives are to study spatial-temporal characteristics of the eco-environment in Fujian province. Based on the theory of Geo-information Tupu and the method coupling environmental information model and modern information technology together, information from both eco-environment and other social economy is processed. Through abstractive generalization by the thought of Tupu, Tupu of spatial-temporal patterns in regional eco-environment can be constructed, and can be used to uncover the spatial-temporal change of spatial form and status for eco-environment and its elements. It also can provide scientific basis and implementary plan and can explore a visible study system of "patterns and processes" in eco-environment. Therefore, this thesis contains:(1) Based on the analysis of interactions between basic environmental factors in Fujian province, we bring forward a basic cluster system for category units of eco-environmental Tupu, based on geomorphology and land cover. Thus, 28 Tupu unit category can be obtained. By integrating RS and GIS, category units of eco-environmental Tupu in Fujian province are acquired in 1988,1995,2001, respectively.(2) By using the PCA and hierarchical analyses, the comprehensive eco-environment is assessed in Fujian province, and it is divide into 6 ranking areas according to the comprehensive evaluation indexes. Based on the results of comprehensive assessment, the spatial units, dynamic index and degree of land utilization is studied, and spatial characteristic information Tupu of the eco-environment is constructed.(3)By using different mathematic models, the information Tupu of "space-attributes-processes" is acquired, through a new combination of eco-environmental Tupu unit for the above three periods in Fujian province, which includes the Tupu of units evolvement, dynamics index of evolvement and landscape change information Tupu.(4) The driving mechanism of spatial-temporal pattern of the eco-environment is...
