Chino. 分析郑州雁鸣湖地区1988－2009年水域景观格局动态变化。利用1988、2001和2009年的遥感数据，借助于地理信息系统技术，对雁鸣湖地区河渠、居民点、水浇地、林地、道路、坑塘和旱地7种景观类型面积的变化进行分析，并对其生态空间动态变化及景观格局指数变化进行分析。1988－2001年、2001－2009年，水域景观中河渠景观面积变化量分别是0.319 1 和2.210 6 km2，变化率分别为14.46%和87.55%；坑塘景观面积变化量分别是10.379 3和－6.556 8 km2，变化率分别为460.91%和－51.91%。水域景观的平均斑块分维数呈减小的趋势，连通性自1988年以来保持着上升趋势。增强水域景观面积和连通性对保持雁鸣湖地区景观多样性具有重要意义。

Based on 1988, 2001 and 2009 remote sensing data and using GIS technology, landscape pattern dynamics of the water body of the Yanming Lake in Zhengzhou were analyzed. From 1988 to 2001, and 2001 to 2009, the landscape area of the river changed by 0.319 1 km2 and 2.210 6 km2, respectively. But the landscape area of the pond changed by 10.379 3 km2 and －6.556 8 km2, respectively. The average fractal dimension of water body landscape reduced. The increased of the area and cohesion index of the water body in the Yanming Lake was very important to the improvement of the landscape diversity.
