\begin{abstract}
In order to reveal the spatial correlation characteristics and action
mechanism of cropland fragmentation and cropland quality, this study
takes the central plain area of Liaoning as an example, constructs the
evaluation system of cropland ``area-shape-distribution'' fragmentation
and cropland natural-standing quality, and explores the effect of
cropland fragmentation on cropland quality based on the evaluation using
bivariate spatial autocorrelation method and spatial lag model. The
results showed that the quality of cropland in the Central Plain region
was affected by the fragmentation. The results showed that the overall
degree of cropland fine-fragmentation in the central plain area was
light, and the cropland quality showed a spatial distribution trend of
``high in the middle and low at both ends''. There was a negative
spatial correlation between cropland fine fragmentation and cropland
quality. The increase of the number of patches (NP), boundary density
(ED) and aggregation degree (AI) in the central plain area will hinder
the improvement of the cultivated land quality. When the NP, ED and AI
values in the evaluation unit increased by 1 unit, the cropland quality
in the central plain area decreased by 0.275, 1.306 and 1.085,
respectively.%
