基于土地利用调查数据开展区域土地利用景观格局的粒度变化效应分析可对该数据在不同尺度下的综合运用提供理论依据。本文运用景观格局指数和GIS空间分析研究方法，以镇江市为例对4种尺度下的景观格局展开研究，结果表明：（1）土地利用景观随着尺度的变化而变化，土地利用景观随粒度变化的幅度与景观类型现状面积呈正相关，而其比率与景观类型面积呈负相关；（2）随着空间粒度的增加，景观破碎度降低，斑块面积向趋于不均匀的方向发展，景观的连接性和优势类型的比重提高；在各用地类型的变化效应方面，基质景观耕地随粒度粗化有空间上连片的趋势，廊道景观连通性降低，非优势景观的斑块逐渐萎缩；（3）粒度变化效应与土地利用景观的分布格局和结构相关。

The analysis on effect of multi-scale granularity change to regional land use landscape pattern based on land use survey datacan provide theoretical basis for the comprehensive use of the survey data. Combined GIS and landscape analysis method,the paper analyzes the landscape patterns in Zhenjiang under four kinds of spatial granularities,the re?sults show that:(1)Land use landscape will change with scale change,land use landscape change range and landscape area are positively correlated,while rate of change and landscape area are negatively correlated.(2)As the spatial granu?larity increases,landscape fragmentation decreases,patch size becomes uneven increasingly,landscape connectivity and the proportion of advantageous types increase;matrix landscape,such as cultivated land becomes more continuous in space as granularity coarsening,connectivity of corridor landscape is reduced,the patches of non-dominant landscape?gradually shrink.(3)The effect of granularity change is related to layout and structure of land use landscape.
