| 摘 要： | 城市湿地是城市重要地生态基础设施，具有重要的生态服务功能。但随着城市化进程地加快，湿地景观受到了严重地破坏。以1988年、1998年和2003年三期TM影像为基础数据源，在Erdas和Arcgis的支持下，通过选取和计算景观指数来分析了开封市湿地景观动态变化。分析结果表明：研究区湿地面积严重减少，湿地景观多样性减少，类型区域单一化，受城市化影响湿地破碎度加大，连通性降低；湿地景观生态环境质量严重下降，生态服务功能明显退化。最后提出了保持湿地景观的自然性，推动自然型河流建设、加大湿地连通性等景观生态保护措施。 |

| Abstract: | As a major life-holding system in cities, urban wetland is an important ecological infrastructure, however rapid urbanization has made wetland declined seriously. Based on the TM image of 1988,1998 and 2003, the change of wetland landscape pattern in Kaifeng City was analyzed with the help of Erdas and Arcgis. The research shows that wetland decreased seriously, landscape diversity index and landscape connectivity decreased a little , and wetland landscape fragment increased,the service of the whole landscape degraded seriously. Finally some countermeasures were brought out. |
| Keywords: | wetland Kaifeng City landscape pattern urbanization |
