| 摘 要： | 本文应用经济学中的洛伦茨曲线和基尼系数,进行吉林西部土地利用结构变化研究。结果表明：洛伦茨曲线出现了“三近三疏”和基尼系数出现了“三增三减”的现象,这恰好与TM遥感解译结果相符,说明该区未利用地面积增加,水域湿地面积减少,生态环境恶化。因此,本研究结果可作为吉林西部土地资源合理利用及结构调整提供科学依据。

| Abstract: | Based on the land use data of the western of Jilin Province in 1989,2000 and 2004 year,the Lorrenze Curve and Gini Coefficients have been used to analyze the land use structure.The results show that the Lorenz curve is at state of "three nearly and three diversion",and the Gini Coefficient of "three increased and three reduced",which coincide with the results of TM interpretation.It not only indicates that the increase of unused land,the reduction of water body and wetland,eco-environment deterioration,but also provide scientific basis for land structure adjustment and land resources utilization. |
