Abstract: Abstract: The purpose of this study is to find out the status level of intensive use of construction land in 22 counties of Ningxia, summarize the spatial distribution characteristics, analyze the problems in land use, and to provide scientific evidence for further improving land management and scientifically formulating targeted management policies. Based on the county scale, this study used multi-factor comprehensive evaluation method to evaluate the intensive use of construction land in 22 counties of Ningxia, and used spatial autocorrelation analysis method to analyze the spatial differentiation of construction land. This study revealed that the spatial differentiation of intensive use of construction land in Ningxia were obvious. Only five counties got more than 80 points, and the land use was highly intensive. The state of intensive use of construction land in Ningxia showed a gradual decline from north to south: The hotspots were concentrated in the northern part of Ningxia; the sub-hotspots were located in the periphery of the hotspots; the sub-cold spots were scattered and scattered; the cold spots were distributed in the central and southern counties. The conclusion of this study is that the intensive use level of construction land in Ningxia is not high and the spatial distribution is extremely unbalanced. It shows strong spatial correlation and obvious spatial agglomeration characteristics. In the future, the northern and southern counties of Ningxia will have to formulate differentiated land management policies based on their own realities. The northern counties with better economic development are mainly to excavate the potential of stock land and improve efficiency of new land; the southern counties are mainly to promote rapid economic and social development and improve land use efficiency.
