Abstract

Land use conflicts are intensifying due to the rapid urbanization and accelerated transformation of social and economic development. Accurate identification of land use conflicts is an important prerequisite for resolving land use conflicts and optimizing the spatial pattern of land use. Previous studies on land use conflict using multi-objective evaluation methods mainly focused on the suitability or competitiveness of land use, ignoring land resource scarcity and the diversity of human needs, hence reducing the accuracy of land use conflict identification. This paper proposes a new framework for land use conflict identification. Considering land use multi-suitability, land resource scarcity and the diversity of human needs, the corresponding evaluation index system was constructed, respectively, and the linear weighted sum model was used to calculate the land use conflict index. Taking Jinan as the study area, the spatial distribution characteristics of land use conflicts are accurately identified and analyzed. The results show that: (1) Land use multi-suitability in Shanghe county and Jiyang district is high, but the intensity of land use conflict is not. This indicates that land use multi-suitability is the premise and basis of land use conflict, but it is not the only determinant, which is consistent with our hypothesis. (2) Land use conflicts in Jinan were dominant by medium conflict, accounting for 43.89% of the conflicts, while strong and weak land use conflicts accounted for 25.21% and 30.90% of the conflicts, respectively. The spatial distribution of land use conflicts is obviously different, with high conflicts in the north and low conflicts in the south. Strong land use conflicts are concentrated in the urban and rural transition zones of Tianqiao, Huaiyin and Shizhong districts and in the northern parts of Licheng and Zhangqiu districts. (3) Inefficient land use and land resource waste aggravated regional land use conflicts in Licheng and Zhangqiu districts. (4) The new framework for land use conflict identification proposed in this study can accurately identify land use conflicts, providing a scientific reference and new ideas for accurate identification of land use conflicts.

Highlights

According to the World Population Change Report published by the World Bank, the global population has increased by approximately 1 billion every 12 years since 1975
The areas with strong land use conflict are mainly distributed in the urban–rural transition zones, which is consistent with the results of previous studies [31,32]
Considering land use multi-suitability, land resource scarcity and diversity of human needs, this paper proposes a new framework to identify land use conflicts and evaluates land use conflicts in Jinan

Summary

Introduction

According to the World Population Change Report published by the World Bank, the global population has increased by approximately 1 billion every 12 years since 1975. As the most populous country in the world, China has experienced unprecedented rapid urbanization and industrialization, with the urbanization level rising from 17.9% before the reform and opening-up to 63.89% in 2020 This extensive development model has made China face increasingly severe land use conflicts, which are mainly manifested in the disorderly expansion of urban and rural settlements occupying high-quality farmland and ecological spaces, leading to the fragmentation of cultivated land and a decline in the quality of the ecological environment, further threatening food security, ecological security and the sustainable development of urban and rural areas [7,8,9,10]. The multiobjective comprehensive evaluation method has obvious advantages compared with other methods [16,18] It can quantitatively evaluate land use conflicts at multiple scales, such as administrative divisions and grids, and can take socioeconomic and natural attributes into account
