- 摘要:
- 为探究边境地区土地利用多功能之间的交互关系,基于生态位宽度、耦合协调度和权衡强度模型分析广西边境地区2000—2018年土地利用“三生”功能的时空演变及协调/权衡关系特征,并分区提出优化建议。结果表明:(1)广西边境地区“三生”功能时空分异特征显著,生产功能生态位宽度以扩张状态为主,呈“东南高、西北低”的梯度变化格局; 生活功能生态位呈萎缩后扩大趋势; 生态功能生态位宽度呈现萎缩态势,呈“双高多平”空间布局。(2)土地利用功能耦合协调类型区分为濒临失调型及勉强协调区,总体由濒临失调型向勉强协调型演变,勉强协调区主要为经济相对繁荣区,濒临失调型集聚在西部生态环境脆弱山区; 两两功能权衡强度较低为防城区,权衡强度较高为那坡县、龙州县。(3)全区可划分为低协调区、生产—生活功能优势区、生产—生态功能优势区、生态—生活功能优势区、生产功能优势区、生态功能优势区、生活功能优势区并提出针对性措施。广西边境地区土地利用“三生”功能之间相互作用关系整体往协调态势发展,后续发展应注重以生态优先为导向。
- Abstract:
- In order to explore the interactive relationship between the multi-functional land use in the border area, the spatial-temporal evolution and coordination/trade-off relation characteristics of the production-living-ecological function of land use in the border areas of Guangxi from 2000 to 2018 were analyzed based on niche breadth, coupling coordination degree and balancing strength model, and optimization suggestions for different zones were put forward. The results show that:(1)the production-living-ecological function in border areas of Guangxi presented significant spatial-temporal differentiation characteristics, the niche breadth of ecological function was mainly in expansion, presenting a gradient pattern of higher level in the southeast and lower level in the northwest; the niche breadth of living functgion was in expansion after shrinking; the niche breadth of ecological function tended to shrink, presenting a spatial layout of double highs and multiple flats;(2)the areas for land use with functional coupling coordination were divided into the areas on the verge of malcoordination and the barely coordinaed areas, in general, the areas were gradually evolved into the latter from the former, the latter mainly covered the areas which were with moderately propserpous economy, while the former clustered in the mountainous areas with fragille ecological environment in the west; Fangcheng District was with low pairwise functional tradeoff intensity, and the Naopo County and Longzhou County were with high trade-off intensity;(3)the whole area could be divided into low coordination area, production-living function dominant area, production-ecological function dominant area, ecology-living function dominant area, production function dominant area, ecological function dominant area, living function dominant area, the corresponding suggestions were provided. The interactive relationship between the production-living-ecological function of land use in the border areas of Guangxi is developing in a coordinated manner as a whole, and the follow-up development should focus on ecological priority.
