基于生态位适宜度的山东省国土空间功能分区研究

Study on spatial functional zoning of Shandong based on niche-fitness

从生态位理论出发,以土地利用区域差异为依据,进行国土空间功能分区研究,能够更好地协调国土空间功能差异与生态建设之间的关系,实现土地资源优化配置与可持续利用。本文基于山东省134个区县,引入生态位适宜度模型,构建适宜性评价指标体系,并结合SPSS、GIS软件将各区县划分为农业发展功能区、城镇发展功能区、生态环境保护区、产业发展功能区、外贸发展功能区等5个国土空间功能分区。研究发现:①生态环境保护与农业发展生态位的值较高,适宜度等级中最适宜和较适宜两个等级的区县处于优势地位,产业发展适宜度偏低,仍存优化空间;②生态环境保护区与主体功能布局中的生态重要性评价区存在较高程度重合;③东部沿海区县功能齐全。结合省总体规划,为山东省国土空间功能协调发展提出建议。

Based on the niche theory and the regional difference of land use,the function zoning of territorial space can better coordinate the relationship between function difference and ecological construction and realize the optimal allocation and sustainable use of land resources.This study introduces the niche fitness model to construct the suitability evaluation index system on account of the data of 134 counties and districts in Shandong Province,and uses SPSS and GIS to divide the counties and districts into five land spatial functional zones,including agricultural development functional zone,urban development functional zone,ecological environment functional zone,industrial development functional zone and foreign trade development functional zone.It is found that the ecological environment protection zone and the agricultural development function zone occupy the dominant position,and the industrial development function zone is at a disadvantage.There is a high degree of coincidence between the ecological environment protection zone and the ecological importance evaluation zone.Eastern coastal counties have complete functions.Finally,combined with the overall planning of Shandong Province,this paper puts forward some suggestions for the coordinated development of land and space functions in Shandong Province.
