运用GIS和统计分析方法，选取景观多样性、优势度、破碎度和斑块平均分维数等指标，分析了江苏沿海城市南通市各城镇的土地利用格局的空间梯度分异。结果表明：南通市各城镇土地利用格局整体上呈现出由沿海沿江到内陆“景观异质性程度降低、斑块破碎化、斑块形状规则化”的变化趋势。利用主成分分析对各乡镇景观格局进行综合评价，把南通市乡镇景观格局特征分为三个类型，即市县政府所在地型、沿江沿海型和内陆型。相关性分析表明城镇人口数量和城镇经济发展水平对城镇景观格局的影响较大。

Using the techniques of GIS and statistical analysis, and selecting some indexes oflandscape pattern, this paper analyzes the spatial difference of landscape pattern of Nantong City, Jiangsu Province. The results show that rules of land use can be found in different towns of the city, i. e. , the diversity index and patch fractal dimension are reducing, and the dominance index and patch fragmentation index are increasing from coastal and riverside region to interior towns. The paper employs the principal component analysis to conduct a comprehensive evaluation of landscape pattern of every town, and then classifies the landscape pattern of the towns into three types, that is, towns of city or county governments are located, coastal and riverside towns, and interior towns. The correlation analysis indicates that population and the level of economic development have had a greater impact on landscae pattern of the towns.
