Abstract
This study collected and analyzed dynamic spatial data of eight traditional villages scattered in different regions of China. A multi-temporal analysis of morphological metrics of spatial patterns and a regression analysis of the morphological evolution were used to analyze and contrast the historical spatial processes of different villages. These were then compared using patch texture and rural macro-morphology perspectives. This led to an assessment of the general laws and trends associated with rural spatial processes. (1) There has been a significant shift in the stability of rural spatial development since the founding of the People’s Republic of China (PRC). (2) Most small and medium-sized villages have maintained a relatively stable spatial texture, while large villages have changed significantly. (3) The mean and variance of the patch area, and the Euclidean nearest-neighbor distance, are correlated in some cases. (4) The mode of rural expansion may be relevant to limitations in the total area of growth. (5) The fractal dimension of the rural macro-morphology may follow a morphological order of oscillation around the equilibrium level. (6) The common mean value of the projected area of rural building patches is expected to be 100 m2.

For morphological metrics, when studying the spatial evolution of villages, the Landscape Expansion Index (LEI) may be no better than the time series analysis with multi-temporal metrics
Summary
The layout of traditional rural residential land constitutes the core framework of the rural cultural landscape. Static morphological metrics merely describe the spatial patches in a single time point They do not reflect dynamic information about the spatial evolution. For morphological metrics, when studying the spatial evolution of villages, the LEI may be no better than the time series analysis with multi-temporal metrics. When the spatial scale for research is narrowed to a single village, building patches are often in a scattered layout, expanding in multiple directions This makes it easy to misjudge the types of spatial expansion when measured by LEI. The general characteristics and development trends of traditional rural spatial dynamics were compared and summarized, providing essential empirical knowledge to support spatiotemporal dynamic modeling and predictions related to rural evolution
