基于“三生”适宜性的县域土地利用冲突识别与分析

精准识别潜在土地利用冲突有利于预警权衡和协调冲突用地,有利于科学进行国土空间规划。以“三调”修正数据为基础,基于生产、生活、生态视角,构建高植被覆盖率县域生产、生活、生态即“三生”适宜性评价模型与土地利用冲突识别矩阵,并选取横峰县进行实证分析。结果表明:（1）横峰县“三生”适宜性用地的空间分布与面积构成差异显著,且存在明显的空间叠加特征,暗示着研究区土地利用存在冲突;（2）从潜在冲突识别的结果来看,土地利用适宜区、冲突激烈区、冲突中度区、冲突一般区及冲突微弱区面积占比分别为64.02%、9.66%、17.19%、1.66%、7.48%;（3）各个冲突类型区空间分布、表现形式的差异性决定了冲突和解的对策也需因地制宜。研究结果可为相关及类似县域的国土空间规划提供理论参考。

Recognition and analysis of land use conflicts at county level based on "Production-Living-Ecological" suitability

Accurate identification of potential land-use conflicts is conducive to early warning, trade-off and coordination of conflict land, so as to promote the scientific planning of land space. In this paper, based on the revised data of the third national land survey, and assuming that a county should at least have ecological function, productivity and suitability for living (ecological-production-living suitability), we proposed an empirical model to identify and diagnose potential land use conflicts in tourism resorts by taking Hengfeng county with high vegetation coverage as an example. The land-use conflict recognition matrix was used in the research, and it includes five zones at different conflicting levels: zone without conflict, zone with intense conflicts, zone with moderate conflicts, zone with general conflicts, and zone with weak conflicts. The results show that: (1) The spatial distribution and area composition of the "Production-Living-Ecological" suitable land in the study county are significantly different, and there are obvious spatial superimposition and conversion characteristics, which indicates the existence of competitions and conflicts in land use. (2) According to the land-use conflict recognition matrix results, the zone without conflict, zone with intense conflicts, zone with moderate conflicts, zone with general conflicts, and zone with weak conflicts accounted for 64.02%, 9.66%, 17.19%, 1.66%, and 7.48%, respectively. Among them, suitable zone for land use are relatively large, the zones with intense, moderate and general levels are reflected in the conflicts between production and life, which are in the transitional stage of human production, life and ecology. (3) The difference in the spatial distribution and manifestation of various conflict types in the study area determines that the countermeasures for conflict reconciliation must adapt to local conditions and be suitable for land use. In other words, targeted measures should be taken in areas with weak, intense, moderate and general conflicts. The research results can provide a theoretical reference for the evaluation of the "Production-Living-Ecological" suitability of land use in counties with high vegetation coverage, as well as a basis for land space planning in asimilar counties.
