摘要：[目的]科学地识别喀斯特乡村生产-生活-生态(“三生”)用地冲突,分析其区域差异特征,为优化国土空间布局,推动乡村振兴提供理论参考。[方法]以贵州省喀斯特中山、喀斯特盆地、喀斯特槽谷、低山丘陵4种喀斯特地貌的典型乡村为例,构建了“三生”适宜性评价体系及用地冲突识别矩阵,并探讨“三生”用地冲突在不同地形梯度上的分布格局。[结果](1)4个典型喀斯特乡村的“三生”适宜性用地空间分布和结构组成存在明显差异,且在空间上存在重叠等突显土地利用冲突现象的特征;(2)土地利用冲突以“生产-生活冲突”和“生产-生态冲突”为主,前者主要分布于地势起伏小的生产-生活热点区,后者主要分布于坡地及生态脆弱区;(3)随着地形梯度增加,冲突强度逐渐降低,即冲突激烈区主要集中于低地形位,冲突微弱区和用地适宜区在高地形位上分布更显著。[结论]典型喀斯特地貌背景下,人类活动受到严重制约,喀斯特乡村土地利用冲突特征明显,亟需因地制宜地优化区域发展空间布局。
[Objective]Accurate and rapid identification of production,living and ecology land use conflicts and analysis on its regional differences characteristics in karst villages can provide reference for optimize the spatial layout of land and implement the rural revitalization strategy.[Methods]In order to explore the characteristics of the‘Production-Living-Ecology’conflicts of different landforms in small scale,the typical towns in four different karst landforms(karst mid-mountain,karst basins,karst troughs and low hills)of Guizhou Province as examples,were used as the examples to construct a‘Production-Living-Ecology’suitability evaluation model and a land use conflict identification matrix,and to explore the spatial distribution of land use conflicts on different terrain gradients.[Results](1)The spatial distribution and structural composition of the‘Production-Living-Ecology’suitable land in the four different karst villages were obviously different,and there were spatial overlaps and other characteristics that characterized conflicts in land use.(2)Land use conflicts were mainly‘production-living conflicts’and‘production-ecological conflicts’,the former mainly distributed in production and living hotspots with small topographic relief,and the latter mainly distributed in slopes and ecologically fragile areas.(3)As the topographic gradient increased,the intensity of conflict decreased,i.e.,the conflict-intense areas mainly concentrated in the low terrain,while the conflict-weak areas and land-use suitable areas more significantly distributed in the high terrain.[Conclusion]Under the background of typical karst landform,human activities are severely restricted,and land use conflicts in karst villages are obvious,so it is urgent to optimize the spatial layout of regional development according to local conditions.
