- Abstract:
-
The essential of ecological civilization construction is the optimization of spatial patterns of geographical space, of which the basis is scientific division into 3 classes: living land, industrial land and ecological land. By classifying the functional land use type, this paper presented a classification scheme including 5 first-class land use types of living land, industrial land, ecological land, eco-industrial land and eco-living land, and 20 second-class land use types, as well as 61 third-class land use types. The paper also established an assessment method of spatial system with index of total departure from regular pentagon (TDRP hereafter) expressing by two-dimensional image, systemically applied for Yangou watershed in Yan’an City. The result showed that the TDRP declined from 0.583 to 0.567 during the year of 1988 to 2010 in Yangou watershed; and the TDRP of all 14 villages in the range of between 0.55 and 0.59, meant highly concentration and not significant difference. The case study also indicates the above method is feasible in functional land use classification.
