Research On Mutual Relationship Between Land Use Structure And Industrial Structure Of Lanzhou City Based On Information Entropy

Socio-economic activities are based on a range of land-based andexpanded,industrial structure’s spatial development mainly relying on land, and thearea of land occupied by industrial sector is closely related to its level of output.Therefore, to some extent, the industrial structure is the land structure. In the the caseof industrial development and land supply increasingly acute, organically combiningthe industry structure and land use structure,researching the relationship betweenthem, consorting land resources optimization in different optimal allocation betweensectors, and resolving how to implement the industrial structure of land use structureeventually,which will become an urgent issue to study.In the case of Lanzhou, land-use change survey data and statistics yearbook from1996to2008are adopted, and the spatial and temporal changes of land use structureand industrial structure are analyzed.On the basis of the information entropy theory,correlation analysis, mathematical statistics, linear regression are adopted to analyzeinternal relations and mutual influence, and investigate the degree of associationbetween the two internal contacts through the rate of change between the twostructures and land-use efficiency. The following are the main conclusions of thestudy:1.Lanzhou’s land use structure and industrial structure in each county show someregional differences.Information entropy of land use structure in Qilihe District is themaximum reaching1.703Knight, but the minimum information entropy is in HongguDistrict,0.954Knight, the city’s land use structure information entropy is1.441Knight. The maximum Information entropy of the industrial structure is in YuzhongCounty, to1.025Knight, the minimum value of information entropy is in ChengguanDistrict,0.526Knight, the industrial structure of information entropy of Lanzhou is0.828Knight.2.Land use structure of Lanzhou in nearly13years has developed to relativelydisordered state, the complexity of land use structure rising and heterogeneityincreasing gradually. Industrial structure has developed to a relatively order state, industrial structure concentration enhancing, mainly as the secondand third industries having obvious advantages, industrial development, completedfrom the "231" to "321" changes in the structure in2005.3.Through correlation Analysis of land use structure and industrial structure,there is a significant correlation between the proportion of each land type andproportion of three industries in Lanzhou: arable land, grassland, are highly correlatedwith the first and the second industries,having a highly negative correlation with thethird industry. Orchard land is negative correlation with the first industry, woodlandother agricultural land, residential and industrial land and transportation land arehighly negatively correlated with the second industry, being highly correlated with thethird industry, unused has a high negative correlation with the frist industry.Information entropy of Both the two structures show a significant negativecorrelation,reaching-0.969,correlation level being0.01,which show the twostructures interact and restrict mutually.4.The overall trend of the rate of change of land use structure in Lanzhou isincreasing year by year, but the rate of change of industrial structure is a fluctuationupward trend. The changes in industrial structure and magnitude of changes isgenerally higher than the one in land use structure. Reasons caused by land-usechanges in structure and industrial structure are different in different stages ofdevelopment, the two structures interact and influent mutually, and both structuraltrend stabilized ultimately.5.Overall, the output value of the city’s three industries and land use are not fullycoordinated. The proportion of primary industry output value is less than the landsupply structure, while the second and third industrial land supply structure is lowerthan the proportion of output value, the degree of disharmony gradually deepen withthe economic growth and upgrading of industrial structure and. In the continuousprocess of development in the industry level, adjusting reasonably the proportion ofthree industries and the proportion of land, improving land use intensity and outputlevel and coordinating the optimal allocation of land resources between the differentindustrial sectors in order to achieve the purpose of rational use of land, which making land use structure and industrial structure adjustment developing towardhealth favorable direction.
