Land use conflicts exacerbate soil erosion and reduce biodiversity, which is detrimental to sustainable development. Multiple methods such as multi-criteria evaluation and landscape pattern indexes can identify land use conflicts, but few studies conform to the concept of green development. The concept of green development gives priority to ecological protection and coordinates the relationship between production development, food production and ecological protection to achieve sustainable development. Taking Jinan City (China) as the study area, we identified the ecological source areas by evaluating the importance of ecosystem service functions and ecological sensitivity, then extracted and optimized the ecological corridor network (using the minimum cumulative resistance model and gravity model), and constructed the ecological security pattern. Spatial overlay analysis of cultivated land, construction land, and the ecological security pattern was performed to identify the types and intensity of land use conflicts. Spatially, we found that ecological land was in more serious conflict with cultivated land than construction land. Different types of land use conflicts have significant differences in spatial distribution. The key to land use conflict mediation in Jinan City is to balance food security with the improvements in the quality of the ecological environment. Hence, it is necessary to delineate the main functional zones and formulate tailored land use conflict mediation strategies in each zone. The method for land use conflict identification proposed here follows the principle of giving priority to ecological protection, providing a scientific reference for the utilization and protection of territorial space in other similar areas.
土地利用冲突加剧了土壤侵蚀,降低了生物多样性,不利于可持续发展。多准则评价和景观格局指数等多种方法可识别土地利用冲突,但符合绿色发展理念的研究较少。绿色发展理念优先考虑生态保护,协调生产发展、粮食生产和生态保护之间的关系,实现可持续发展。以中国济南市为研究区,通过评价生态系统服务功能重要性和生态敏感性,确定了生态源区,然后提取和优化了生态廊道网络(采用最小累积阻力模型和重力模型),构建了生态安全格局。对耕地、建设用地与生态安全格局进行空间叠置分析,识别土地利用冲突的类型和强度。空间上,发现生态用地与耕地的冲突比与建设用地的冲突更为严重。不同类型的土地利用冲突在空间分布上存在显著差异。济南市土地利用冲突调解的关键是在保障粮食安全的基础上,改善生态环境质量。因此,有必要划定主要功能区,并在各功能区制定有针对性的土地利用冲突调解策略。本文提出的土地利用冲突识别方法遵循生态保护优先原则,为其他类似地区的国土空间利用和保护提供了科学参考。
