摘要： 通过研究崇明植被覆盖度及其景观特征历时17年的动态变化，再现了城市化进程对自然景观的干扰过程以及生态环境质量的变化.用TM/ETM+遥感影像解译区域植被覆盖度并进行其等级结构的时空特征分析，结果表明：1989～2006年间，经济发展迅速的崇明，其植被系统经历了从严重破坏到逐步恢复的过程.1989～2001年间，崇明县乡镇区和农场区植被受到破坏都较为严重；2001～2006年间，这种趋势在乡镇区没有根本改变，但农场区在这一期间植被覆盖度增加，植被覆盖度的等级结构也获得改善，而这一过程对全县植被系统的恢复做出了积极的贡献.

Abstract: By studying the vegetation coverage and it’s pattern during 17 years by means of translation of TM/ETM+ remote sensing images and analysis on the tempo-spatial characteristics of the hierarchical structure of the vegetation coverage, the process of disturbance of urbanization on the natural landscape and the changes in environmental quality were reproduced. The results showed that from 1989 to 2006, along with the rapid development of economy, the vegetation system in Chongming county experienced a process from serious damage to gradual restoration. From 1989 to 2001, the vegetation in both town and farm areas were destroyed seriously. From 2001 to 2006, this tend still existed in the town area, but in the farm area, the vegetation was increased, and the hierarchical structure of the vegetation coverage was improved, which positively contributed to the restoration of the vegetation system in Chongming county.
