摘要:为开展南水北调中线工程建设背景下土地利用结构及产业结构的动态变化特征分析研究，以河南省南水北调中线水源地南阳市为研究区，利用南阳市2009—2016年土地利用数据和产业结构数据，运用信息熵模型、相关性分析、多元线性回归分析等方法分析南阳市土地利用结构变化与产业结构现状及两者间相互关系。结果表明：（1）南阳市建设用地（城镇村及工矿用地、交通运输用地）面积呈上升趋势，农用地（耕地、园地、林地、草地）面积呈下降趋势；（2）产业所占比重逐渐呈现“二、三、一”特征；（3）土地利用结构信息熵、均衡度呈上升趋势，土地利用结构复杂度变高，均衡度逐渐增强，产业结构信息熵呈波动下降趋势，产业结构不断优化；（4）第一产业与第三产业对土地利用结构影响最大，说明第一、三产业结构变化是影响土地利用结构信息熵的主要驱动因素。

Abstract:Under the background of the South-to-North Water Diversion Project，taking Nanyang City as the study area，the relationship between land use structure and industrial structure change was studied.Land use data and three industrial structure data in Nanyang from 2009 to 2016 were collected.Firstly，the current situation of land use change and industrial structure in Nanyang was studied.Then the relationship between them was analyzed by information entropy model，correlation analysis and multiple linear regression analysis.The results showed that：（1）The area of construction land has shown an upward trend and the area of agricultural land has shown a downward trend；（2）The industrial structure has gradually shown the characteristics of “two，three and one”；（3）The information entropy and equilibrium degree of land use structure has shown an upward trend，the complexity of land use structure became higher and the balance of land use structure gradually increased，the information entropy of industrial structure was decreasing，the industrial structure has been continuously optimized；（4）The change of land use structure has been most affected by the primary industry and the tertiary industry.It showed that the primary industrial structure and the tertiary industrial structure were the main driving factors affecting the information entropy of land use structure.

Key words:land use;industrial structure;information entropy;correlation analysis;linear analysis
