摘要:
[目的] 对桂西南-北部湾地区进行"三生"空间适宜性评价,为复杂的过渡性地理空间实现"三生"协调和陆海统筹提供参考,为科学划定国土空间布局提供理论支持。[方法] 构建桂西南-北部湾"三生"空间适宜性评价指标体系,利用变异系数法确定指标权重,综合运用ArcGIS技术对评价结果进行叠加分析。[结果] ①生产适宜性与生态适宜性在桂西南喀斯特与北部湾地区组成的过渡性复杂地理空间分布特征具有"互异性",从喀斯特到海岸带地区,生产空间适宜逐级递增,生态空间适宜逐级递减。②生活空间适宜性等级以城市为中心向周围递减,喀斯特地区的生活空间适宜性总体上弱于北部湾地区。③在复合空间适宜性评价中,以生态空间为主导的复合空间比例最大(接近1/2),生产空间次之,生活空间最小。④海洋"三生"空间适宜性比例由大到小依次为:生产-生态-生产生活,沿岸海洋生态空间与陆地生产生活空间存在冲突。[结论] 生态和生产空间适宜性主要受自然条件制约,生活空间适宜性主要受行政区位条件影响。海岸带的生态保护与社会经济发展存在博弈现象。

Abstract:
[Objective] The suitability of ecological-living-industrial spaces in the Southwestern Guangxi-Beibu Gulf region was evaluated in order to provide a reference for the complex transitional geographic space to achieve the ecological-living-industrial and land-sea coordination, and to provide theory for scientifically delineating the spatial layout of the land.[Methods] The spatial suitability evaluation index system of ecological-living-industrial in Southwestern Guangxi-Beibu Gulf region was constructed. The coefficient of variation method was used to determine the index weights, and the evaluation results were analyzed by ArcGIS technology.[Results] ① The industrial and ecological suitability in the transitional and complex geographic spatial distribution characteristics of the karst and Beibu Gulf region in Southwest Guangxi Zhuang Autonomous Region showed "mutual-differences". From karst to coastal areas, the production space suitability increased gradually, but the ecological space suitability decreased gradually. ② The suitability of living space in karst area was generally weaker than that of Beibu Gulf region. ③ In the suitability evaluation of composite space, the proportion of compound space dominated by ecological space was the highest (accounting for nearly 1/2), followed by production space sand the living space. ④ The proportion of marine ecological-living-industrial suitability in descending order was production-ecology-production and living, and there was a conflict between coastal marine ecological space and terrestrial production and living space.[Conclusion] The suitability of ecology and production space is mainly restricted by natural conditions, and the suitability of living space is mainly affected by administrative location. There is a game between ecological protection and social and economic development in coastal zone.
