An Analysis of Land-Use Conflict Potential Based on the Perspective of Production–Living–Ecological Function

Under the influence of human activities, natural climate change and other factors, the function-folding phenomenon of land use has appeared in China. The conflict levels of different land-use functions has intensified. Based on the perspective of production–living–ecological function, we constructed a land-use function evaluation model by using a multi-criteria evaluation analysis (MCE) method. According to the different arrangement and combination of each function intensity of land units, we constructed an intensity diagnosis model of land-use function conflicts (LUFCs) and divided LUFCs into eight types and four stages. The LUFCs potential was calculated and divided into four ranks, represented by four types of LUFC potential zones. We selected western Jilin Province, a typical, ecologically fragile area in Northeast China, as an empirical analysis area. Empirical research showed that the production, living and ecological functions in western Jilin Province were at low, high and medium intensity levels, respectively, in 2020. The proportions of different LUFCs stages were 54.90%, 24.99%, 19.06% and 1.05%, respectively. The entire study area was basically at risk of potential conflicts, with the area’s proportions accounting for 17.50%, 40.75%, 24.55% and 17.20% from zones of low potential to extreme potential. The hot spots for LUFC potential were concentrated in the east and south of the central area, which were basically consistent with the hot spots’ aggregation areas of LUFCs. The models and indicators established in this research can better reflect the conflict associated with regional land use, which can provide reference for land space planning and management.
