【摘要】：产业结构的空间发展主要以土地为依托，，社会经济的活动都是以一定范围的土地为基础而展开的，各产业部门占用土地的面积与其产出水平密切相关。因此在一定程度上，产业结构就是用地结构，在产业发展和土地供给矛盾日益尖锐的情况下，把产业结构和土地利用结构有机的结合起来，研究它们之间的相互关系，协调土地资源在不同产业部门间的优化配置，并解决如何将产业结构最终落实到土地利用结构上将成为当前迫切需要研究的课题。本文以兰州市为例，采用19962008年土地利用变更调查数据以及统计年鉴资料，对土地利用结构与产业结构的时空变化进行深入的分析，在信息熵原理的基础上，采用相关性分析、线性回归分析的数理统计方法，研究了二者内在的关系和相互影响，并通过二者之间的结构变化率和用地效益探讨了二者内部联系的关联程度。主要研究结论有： 1、兰州市各县区的土地利用结构及产业结构均呈现出一定的区域差异性。七里河区的土地利用结构信息熵最大，达到1.703奈特，红古区的信息熵最小，为0.954奈特，全市的土地利用结构信息熵为1.441奈特。产业结构信息熵值最大的是榆中县，达到1.025奈特，信息熵值最小的是城关区，为0.526奈特，而兰州市的产业结构信息熵是0.828奈特。 2、兰州市近13年的土地利用结构向相对无序状态发展，土地利用结构的复杂程度上升，均质性逐渐增强。产业结构向相对有序状态发展，产业结构集中度增强，主要表现为第二、三产业具有明显的优势度，并且在2005年，产业发展完成了由二三一向三二一结构的转变。 3、通过对土地利用结构及产业结构的相关性的分析，得出兰州市各用地类型比重与三次产业比重之间存在明显的相关性：耕地、牧草地与一二产业呈高度正相关，与三产呈高度负相关，园地与一产呈负相关性，林地、其他农用地、居民点及工矿用地和交通运输用地与一二产业呈高度负相关，与三产呈高度正相关，未利用地与一产呈高度负相关。二者结构的信息熵整体呈现显著的负相关，达到-0.969，相关性水平为0.01，说明二者之间是相互影响、相互制约。 4、兰州土地利用结构变化率整体趋势在逐年上升，而产业结构变化率呈波动上升趋势。而且产业结构变化及变化幅度普遍高于土地利用结构变化。在不同的发展阶段，引起土地利用结构和产业结构变化的原因不同，二者相互作用、相互影响，最终二者结构变化趋势都趋于稳定。 5、总体来看，全市三次产业的产值与用地之间都不是完全协调的关系。第一产业的产值比例低于土地供给结构，而第二和第三产业的土地供给结构低于产值比例，不协调程度随着经济增长和产业结构升级而逐步加深，在产业水平不断发展的过程中，合理调整三次产业比重，同时也要合理调整各用地比例，提高土地利用集约度和产出水平，协调土地资源在不同产业部门间的优化配置，以达到合理利用土地的目的，使土地利用结构系统和产业结构调整向健康有利的方向发展。
[Abstract]:The spatial development of industrial structure is mainly based on land, and the activities of social and economic activities are based on a certain range of land. The area of industrial sector occupying land is closely related to the level of its output. Therefore, to a certain extent, the industrial structure is the land structure, and the contradiction between the industrial development and the supply of land is increasingly sharp. Under the circumstances, it is necessary to combine the industrial structure with the land use structure, study the relationship between them, coordinate the optimal allocation of land resources among different industrial departments, and solve the problem of how to eventually implement the industrial structure to the land use structure.
Taking the Lanzhou city as an example, using the 19962008 year land use change survey data and the statistical yearbook data, this paper makes an in-depth analysis on the spatial and temporal changes of the land use structure and industrial structure. On the basis of the information entropy principle, the correlation analysis and the mathematical statistics method of linear regression analysis are adopted to study the internal relations and phases of the two. The relationship between the two internal relations is discussed through the structural change rate and the land use efficiency between the two.
1, the land use structure and industrial structure of all the counties in Lanzhou show a certain regional difference. The information entropy of the land use structure in Qilihe area is maximum, reaching 1.703 NAT. The information entropy of the red ancient area is the least, it is 0.954 NAT. The information entropy of the land use structure of the city is 1.441 NAT. The information entropy of the industrial structure is the largest in Yuzhong county. To reach 1.025 NAT, the lowest information entropy is Chengguan District, 0.526 NAT, while the industrial structure information entropy of Lanzhou is 0.828 NAT.
2, in the last 13 years, the land use structure of Lanzhou has developed to a relatively unordered state. The complexity of the land use structure has risen, the uniformity of the structure has gradually increased. The industrial structure has developed towards a relatively orderly state, and the concentration of industrial structure is enhanced. The main performance of the industrial structure is the obvious dominance of the second, third industry. In 2005, the industrial development was completed by two. The transformation of the 31 to the 321 structure.
3, through the analysis of the correlation between land use structure and industrial structure, it is concluded that there is a significant correlation between the proportion of land use types and the proportion of three industries in Lanzhou: cultivated land, herbage land and the one or two industry are highly positively correlated, with a high negative correlation with three production, and a negative correlation between the garden land and the first production, woodland, other agricultural land and residential areas. The industrial and mining land and transportation land are highly negatively related to the one or two industry, and have a high positive correlation with the three production, and the unutilized land has a high negative correlation with one production. The information entropy of the two structure has a significant negative correlation, reaching -0.969 and the correlation level of 0.01, indicating that the two are interrelated and restricted to each other.
4, the overall trend of the change rate of land use structure in Lanzhou is increasing year by year, and the change rate of industrial structure is fluctuating. Moreover, the change and range of industrial structure are generally higher than the change of land use structure. In different stages of development, the reasons for the change of land use structure and industrial structure are different, the two interaction and mutual reflection are different. In the end, the change trend of the two structure tends to be stable.
5, in general, the output value of the three industries in the city is not fully coordinated with the land use. The proportion of the output value of the first industry is lower than the land supply structure, and the land supply structure of the second and third industries is lower than the proportion of output value. The degree of incoordination is gradually deepened with the economic growth and industrial structure upgrading, and the industrial level is constantly issued. In the course of the exhibition, the proportion of the three industries should be adjusted reasonably, at the same time, the proportion of land use should be adjusted reasonably, the intensivism and output level of land use should be improved, the optimal allocation of land resources in different industrial sectors should be coordinated so as to achieve the purpose of rational use of land, and make the land use structure system and industrial structure in the direction of health favorable.
