Delineating Method of County Production-Living-Ecology Space in the Grand Canal Based on Three-dimensional Rubik's Cube Model
Three-dimensional Rubik's Cube model is a quantitative method to determine the multi-functional dominance of spatial elements,which can represent the optimal combination pattern of spatial functions.The method provides key technical support for identifying county spatial functions in the Grand Canal.The function suitability evaluation system for the functions of production-living-ecology space in counties along the Grand Canal has been established based on the spatial functions of production-living-ecology space.Based on the three-dimensional Rubik's Cube model,a rule for delineating the spatial scope of production-living-ecology space was proposed,with the Qingxian section of the Grand Canal basin as the research object.The spatial scope of production-living-ecology space was delineated and optimization suggestions were proposed.Results show that there are 60.46％,33.52％and 6.02％of ecology space,production space,and living space in Qing County,respectively.The scope is demarcated by the rules of single-function suitability and multiple-function suitability combination in the Grand Canal based on the three-dimensional Rubik's Cube model.The ecology space is mainly distributed on both sides of the Grand Canal,including 550.58 km2 of high and the highest suitable space,which is the best ecology background of the Grand Canal basin.The suitable,low suitable,and unsuitable space of the living and production functions of 48.23 km2 is the key area for ecological restoration in the Grand Canal Basin.These results enrich the methods and technical means of demarcating the scope of production-living-ecology space and provide a theoretical basis for the territorial space management and comprehensive utilization of the Grand Canal Basin.
