【目的】以大庆典型城市湖泊湿地为研究对象，探讨并揭示城市化过程中湖泊湿地周边缓冲区不同土地利用方式与水环境的响应关系。【方法】在 RS 和 GIS 技术支持下，基于2009年高分辨 GeoEye-1卫星遥感数据和2009年3月至2010年2月期间的水质监测数据，运用 GIS 空间分析技术以及 SPSS 统计分析的方法，计算和分析湖泊湿地缓冲区内土地利用类型的面积比重与湖泊湿地水质的相关关系。【结果】结果表明，缓冲区内土地利用方式对湖泊湿地水质具有明显的尺度依赖性和尺度效应。在1000 m 和500 m 尺度上，草地是影响水环境质量的关键因素，草地的面积比重与水体中 NH3-N、TN、CODMn 含量呈显著负相关；100 m 尺度上，沼泽、草地是影响水环境质量的关键因素，草地的面积比重与水体中 NH3-N、TN、CODMn 含量呈显著负相关，沼泽面积比重与总氮（TN）含量呈显著正相关。【结论】城市湖泊湿地水质受缓冲区土地利用方式的影响明显，且水质对缓冲区土地利用及其格局呈现多尺度响应关系。

Abstrzct:[Objective]The typical lake wetland in Daqing city was regarded as a research objective to explore the effects of land use types in the buffer zone surrounding the lake wetlands on water quality.[Method]With the support of RS and GIS technology,based on the GeoEye-1 high reso-lution satellite remote sensing data in 2009 and the monitoring data of water quality during the pe-riod from March 2009 to February 2010,GIS spatial analysis technology and SPSS analysis were used to analyze the relationship between the area proportion of land use types in the buffer zone and water quality.[Results]As a result,land use type in the buffer zone has an obvious scale de-pendence and scale effect on the water quality.On the 1 000 m and 500 m scale,the grassland was a key factor affecting water quality.Proportion of grassland was significantly negatively correlated with NH3-N,TN and CODMn content in water.On the 100 m scale,swamp,grassland was key factors affecting water quality.Area proportion of grassland was significantly negatively correla-ted with NH3-N,TN and CODMn content in water.However,area proportion of swamp was sig-nificantly positively correlated with NH3-N,TN and CODMn content in water.[Conclusion]The water quality of urban lake wetlands is obviously affected by land use type in the buffer zone and the responses of water quality to land use was shown on the multi-scales.
