Spatial Correlation Analysis of Land Use Pattern: A Case Study of Tonglu in Zhejiang

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 nonstationarity. 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.
