| 摘 要： | 分析边境地区土地利用变化对优化国土空间开发保护格局和实现兴边富民具有现实意义。该研究以广西边境地区为研究对象,在推演基于"三生"空间的"要素-结构-空间-功能"的土地利用多功能机制基础上,构建评价指标体系,运用动态度、转移矩阵模型分析该地区2000-2018年"三生"空间格局演变特征,采用TOPSIS和障碍度模型测度其多功能水平并诊断主要障碍因素。结果表明:1)2000-2018年广西边境地区"三生"空间格局演变速度由平缓转向加速波动,生产空间和生活空间扩张,生态空间收缩,城镇化水平较高和边境贸易活动频繁的中部-东南部沿线的县市区土地利用格局演变更为剧烈;2)2000-2018年广西边境地区土地利用"三生"功能稳速上升,生活功能评分最高,生产功能和生态功能波动式变化明显,土地利用多功能呈现"双核双副"的格局特征,各县市区土地利用多功能由低水平高差距阶段迈向较高水平的相对均衡状态,土地利用格局演化与多功能变化特征一致;3)广西边境地区土地利用多功能的障碍因素主要包括资源要素布局、经济发展水平、生态环境质量和边境贸易活动。需在新一轮国土空间规划指引下,优化旅游资源布局,推动区域经济一体化发展和加快推进生态文明建设,促进广西边境地区土地利用"三生"功能协调发展以提升多功能整体效应。

| Abstract: | Changes in land use have posed a great challenge to the development and protection of national land space in the border areas. Taking the China-Vietnam border areas in the Guangxi Zhuang Autonomous Region as the research object, an evaluation index system was constructed in this study to deduce the multifunctional system of land utilization using "elements-structure-space-function" of the production-living-ecosystem space (PLE). The dynamic index and transition matrix model were applied to analyze the PLE evolution of the spatial pattern from 2000 to 2018. TOPSIS method and the obstacle model were adopted to measure the multifunctional level, further to diagnose the main obstacle factors. The results showed that: 1) The evolution speed of PLE spatial pattern changed from mild to accelerated fluctuation, indicating an obvious periodic characteristic . Specifically, a slow evolution period was from 2000 to 2010, while an accelerated period was from 2010 to 2018. The spatial comprehensive dynamic index of PLE increased from 0.07 to 0.20, where the mutual transfer area between spaces of the PLE was totaled 85218.32hm2. The production space and living space increased by 1145.97hm2, and 3166.77hm2, respectively. The area of ecosystem space decreased by 4312.69hm2. There was a much more violent evolution of land use pattern at all county-level, including Pingxiang City, Dongxing City and Fangcheng District, indicating relatively high urbanization and frequent border trade in the middle-southeast area. 2) Functional level for the land use of the PLE improved relatively fast. Specifically, the functional level of life was the highest with the comprehensive appraisal index of 0.86, increasing by 0.71 in 2000. The functional level of the production was listed as the second, with the comprehensive appraisal index increased by 0.25, an increasing rate of 69.99%. The functional level of the ecosystem was the lowest, with the comprehensive appraisal index increased by 0.13, an increasing rate of only 28.22%. There was obvious fluctuation for the functional level of the production and ecosystem. The multifunctional level of land utilization increased from 0.32 to 0.68. The multifunction of the land utilization in counties and cities changed from the low level and large gap to relatively balanced, representing "two cores and two subs" pattern. There were the same characteristics in the pattern evolution of the land utilization and multifunctional change. 3) The main obstacle factors included resource elements layout, economic development level, ecological environment quality, and border trade. In the function of life, the main obstacle factors were the low richness of tourism resources and low average tourism income in different areas. In the function of production, the main obstacle factors were the low investment in urban fixed assets and low average foreign trade in different areas. In the function of ecosystem, the main obstacle factors were the decreased forest coverage and insufficient capacity for sewage treatment. A recommendation was made to optimize the tourism resources layout, regional economic integration, and the construction of ecological civilization for a better multifunctional effect on the land utilization of the PLE in the China-Vietnam border areas. |
