摘要:

旨在为优化配置土地资源及促进区域生态、社会、经济可持续发展提供理论参考和数据支持,本研究通过构建土地利用效益评价指标体系和耦合协调度模型,引入相对发展度和障碍度模型,探究了山东省17地市土地利用生态-社会-经济系统耦合协调度时空演变特征及主要影响因素。结果表明,2008—2017年间,山东省土地利用生态-社会-经济系统整体处于磨合阶段的初级协调状态,耦合协调度多年均值为0.63,且呈持续上升趋势,由0.54提升至0.70;各地市间耦合协调度均衡化水平逐步提高,变异系数由0.126降至0.072,但仍呈现出较明显的自鲁东至鲁中、鲁西地区递减的梯度分布差异;各地市土地利用生态、社会、经济子系统间相对发展度差异显著,至2017年,威海市同鲁中地区南部两侧及其以北构成了明显的半圈式生态滞后区;影响土地利用生态、社会、经济耦合协调发展的社会经济障碍一直占据主导,但2013年后生态影响有所增强。研究期内,山东省各地市土地利用生态-社会-经济系统耦合协调水平不断提高,但区域间差异性仍较明显,尚有较大改善空间,建议各地市考虑其主要障碍因子,执行因地制宜的差别化发展战略。

Abstract:

The purpose is to provide theoretical reference and data support for optimizing the allocation of land resources and promoting the sustainable development of regional ecology, society and economy. Based on the construction of the evaluation index system of land use benefit, using the models of coupling coordination degree, relative development degree and obstacle degree, the spatial-temporal evolution characteristics and major influencing factors of the coupling coordination degree of land use ecology-society-economy system in 17 cities of the Shandong Province were explored. The results are as follows. Land use ecology-society-economy system of Shandong was in the primary coordination state of running-in stage and showed a continuous rising trend in 2008-2017. The coupling coordination degree increased steadily from 0.54 to 0.70, and its annual average was 0.63. The equilibrium level of coupling coordination degree among cities was gradually improved in 2008-2017. Its variation coefficient of coupling coordination degree decreased from 0.126 to 0.072, but the coupling coordination degree of land use ecology-society-economy system in different cities still showed an obvious gradient distribution difference from the east to the west of the province. There was a significant difference in the relative development degree among the ecological, social and economic subsystems of land use in different cities. The southern sides of central Shandong and its northern area, together with Weihai City, had constituted an obvious half-circle ecological lag region by 2017. Social and economic barriers affecting the coupling coordinated development of land use ecology, society and economy were dominant throughout, but the ecological impact increased since 2013. During the study period, the coupling coordination level of land use ecology-society-economy system in different cities in Shandong was continuously improved, but the differences among different regions were still obvious, and there was still more space for improvement. Therefore, it is suggested that different cities should consider the main obstacle factors of their own and implement differentiated development strategies according to local conditions.

Key words: land use ecology-society-economy system, coupling coordination degree, relative development degree, obstacle degree, Shandong Province
