A method for measuring the carrying efficiency of construction land based on data mining

Abstract

The invention discloses a construction land bearing efficiency measuring method based on data mining. The construction land bearing efficiency measuring method includes steps of S1, mining data to use network open data as main data source and conventional data like demographic census data as complementary, and searching spatial characteristics of construction land bearing efficiency; S2, analyzing data, to be specifically, analyzing addresses in online shopping data and enterprise data; S3, matching data space, subjecting the address analysis data to coordinate conversion after data is collected into position data available for a GIS (geographic information system) platform and correlating the position data with the construction land; S4, realizing regional difference measurement of the construction land bearing efficiency by comprehensive measurement according to multi-element characteristics of the data. By the data mining, the relevant network open data is acquired; by space address matching, social activities of enterprises or microcosmic individual residents are reflected and the problem about measurement of the construction land bearing efficiency is solved.

Description

technical field [0001] The invention relates to the research field of carrying efficiency of construction land, in particular to a method for measuring the carrying efficiency of construction land based on data mining. Background technique [0002] In the related research on the carrying efficiency of construction land, some foreign scholars have recently used the ordered response model to study the relationship between land development intensity and landowners (Nazneen Ferdous, 2013). For the diversified development of residential activities (Yin, el al, 2011) are also involved. In China, scholars have long proposed the necessity of intensive land use (Gu Xiang et al., 2006), and Zeng Yong et al. (2004) also studied the matching between land use and population size. Many scholars study land use efficiency from an economic point of view, including establishing a theoretical model of total factor land use efficiency (Zhao Xiaobo, 2013), using DEA method for model research (Y...

Problems solved by technology

[0005] In reality, the domestic planning field has always been clumsy at measuring the carrying efficiency of construction land, relying mostly on economic statistical yearbook data and other methods. Although this coarse-caliber research method can distinguish the pros and cons of the urban built environment at the macro scale, it is limited by the Due to the limited spatial scale, it is impossible to distinguish the spatial characteristics of land bearing efficiency in more detail

On the other hand, the carrying efficiency of construction land cannot be separated from the activities of social individuals. Although the carrying efficiency measurement of statistical yearbook data can be used to calculate the overall degree of urban development, this structural measurement tends to ignore individual spatial activities, and is even inconsistent with citizens. a clear break in the daily behavior of
