中文摘要：

基于区域水土资源耦合关系及其开发利用的博弈分析,以西安浐灞生态区为对象,对区内2001-2011年土地利用结构动态变化信息熵和均衡度进行分析,选取地均国内生产总值、城镇化水平、生态服务价值作为评价指标,并计算复合开发后的综合效应指数,应用灰色系统理论计算分析不同土地利用结构与综合效应之间的关联度。结果表明：动态变化信息熵由2004年前的1.5上升至2011年的1.795 3,土地结构均衡度（J）上升至0.788 2,土地利用结构变化显著;土地利用综合效应指数值由2004年的0.207 8上升到2011年的0.835 7,土地利用结构与综合效应灰色关联度排序为r11〉r9〉r2〉r5〉r7〉r3〉r4〉r6〉r8〉r1〉r10,表明复合开发后水土资源综合效应明显提高,其主要驱动因子为信息熵和水域利用。

英文摘要：

Based on the coupling relationship between regional water and soil resources and the game analysis on development and utilization of them,the information entropy and equilibrium of land use structure dynamic change in Xi＇an Chanba ecological zone from 2001 to 2011,were analyzed.GDP,the level of urbanization,the ecological service value were selected as the evaluation index to calculate the comprehensive effect index after complex development.The gray system theory had been used to calculate and analysis the correlation between different land use structure and the combined effect.The research results showed that the information entropy rose from 1.5 in 2004 to 1.795 3 in 2011,and the balance degree of land structure（J） rose to 0.788 2 in 2011.Namely,the land use structure changed greatly and tended to rationalization.The combined effect index of land use rose from 0.207 8 in 2004 to 0.835 7 in 2011,and the gray correlation between different land use structure and the combined effect was： r11 r9 r2 r5 r7 r3 r4 r6 r8 r1 r10,which showed that the combined effect of soil and water resources was improved significantly after complex development,and its main driving factors were the entropy and water use.
