摘　　要：本研究在ARCGIS9.0支持下,以福清市为研究区,分析景观全局分布趋势,结果显示:研究区景观空间分布具有明显的规律性,基于面积加权的景观类型空间分布主导方向近似西北—东南向;基于土地利用人为影响指数的景观类型沿着地势降低的方向变化平缓,与之垂直的方向人为影响指数值从西南向东北方向先递增后递减,拟合线近似抛物线,沿着该方向人为影响程度差异较大、变化剧烈.Explored by ARCGIS9.0,the article takes Fuqing for example,and analyzes the trend of landscape. The resuits indicate that： Regularity of landscape spatial distribution exists obviously in the researching region. Based on the area weight,the dominant direction on spatial distribution of landscape types is northwest-southeast; based on the Human Affection Index, the landscape types change slimly in the direction of terrain decline, but change greatly in the vertical direction. At the beginning, the HAI increases gradually and declines slackly at the end. The HAI trend line likes parabola, along the parabola the human affection difference is great.
