空间关联是地理空间现象和空间过程的本质特征。土地利用数据存在空间依赖关系，研究土地利用空间关联特征，对于理解区域土地利用格局的形成具有重要意义，也可为加强土地规划管理和促进土地可持续发展提供参考依据。本文以浙江省桐庐县为研究区，以空间统计学理论为支撑，结合GIS技术方法，通过构建距离标准和邻接标准的空间权重矩阵，从全局空间自相关和基于空间不平稳性的局部空间自相关两个角度对桐庐县土地利用格局进行多尺度空间关联分析。结果表明，桐庐县各种土地利用类型均存在不同程度的空间自相关性，且空间自相关性与空间尺度密切相关，同时，桐庐县土地利用表现出空间不平稳性，既有局部的空间集聚，也因存在少量空间异质性而呈现局部离散格局。

Spatial association is the essential characteristics of geographical phenomena and spatial processes. Land use data has the spatial dependencies. The researches of land use spatial pattern characteristics can be of great significance to understand the formation of regional land use structure, and provide reference for strengthening the management of land use planning and promoting land sustainable development. Supported by spatial statistics theory and GIS technology, this article took Tonglu County as the research area, then built spatial weight matrix based the distance standard and adjacent standard, so as to analyze the multi-scale spatial correlation of land use pattern in Tonglu County through the global spatial autocorrelation and local spatial autocorrelation based on spatial non-stationarity. The results showed that different types of land use in Tonglu County had disparate degree of spatial autocorrelation, and the spatial correlation and spatial dimensions were closely related. Meanwhile, the land use pattern in Tonglu County exhibited distinct spatial instability and spatial heterogeneity. It not only showed a local spatial agglomeration, but also presented a local discrete pattern due to little spatial heterogeneity.
