Abstract

The scientific analysis of spatial-temporal differentiation characteristics and driving factors of illegal land use is of great significance for the formulation and optimization of policies to control the emergence of illegal land use. This paper establishes two variable systems of illegal land use and its driving factors, defined the multidimensional characteristic variables of illegal land use and analyzes the relationships among them by the Pearson’s correlation coefficient; In addition, the spatial–temporal characteristics of each variable of illegal land use from 2004 to 2017 are described by the spatial autocorrelation analysis; Finally, based on the geographical detectors, the influence direction and degree of the factors of economic structure, social structure and land market behavior on the characteristics of different illegal land use are studied. The results show that the spatial agglomeration of different characteristics of illegal land use had been weakening from 2004 to 2017, but the rate of weakening was different, and L-L agglomeration changed between Xinjiang and other central-western provinces, H-H agglomeration changed in the coastal regions of the central-eastern of China, the level and ability of the central government and local governments to govern illegal land use is constantly improving on the whole; the compositional factors of economic development structure, social development structure, and land market behavior of driving factors had different influence in the degree, the location or the direction of different characteristics of illegal land use. According to the spatial–temporal characteristics and the differences of driving factors, managers can formulate differentiated illegal land use control policies, which will help to control the occurrence of illegal land use and help the settlement of illegal land use cases, and ultimately achieve sustainable development.

Highlights

The contradiction between the supply of land for human production and living activities and the demand for land has become increasingly prominent with the rapid development of the global economy and society, which has led to cases of illegal land use occurring all over the world, and this phenomenon is serious in developing countries with large populations and rapid economic-social development [1,2,3]
The analysis of the spatial–temporal characteristics of illegal land use and its driving factors can guide the formulation of effective policies and measures to prevent or solve illegal land use cases, and it is of great significance to promote the legal utilization of land resources and the sustainable development of mankind
Judging from the results of CasesULY’s global Moran’s I and critical value (z-score), it showed a certain spatial autocorrelation before 2009 that indicated that CasesULY showed the characteristics of spatial aggregation in China before 2009; judging from the results of VLDCY’s global Moran’s I and critical value (z-score), VLDCY showed a random distribution only after 2012; from the results of CasesSTY’s global Moran’s I and critical value (z-score), CasesSTY showed the characteristics of clustering distribution from 2004 to 2007; CLICULY showed the characteristics of clustered distribution before 2011

Summary

Introduction

The contradiction between the supply of land for human production and living activities and the demand for land has become increasingly prominent with the rapid development of the global economy and society, which has led to cases of illegal land use occurring all over the world, and this phenomenon is serious in developing countries with large populations and rapid economic-social development [1,2,3]. In China, the basic system of society decides that the right to allocate the land that carries main social-economic activities is in the hands of the government or village unity [4,5], and China takes advantage of this unique system to carry out strict farmland protection system and limited supply of construction land to ensure food security and the realization of sustainable development goals [6].
