摘要
主体功能区规划促进了社会经济与资源环境的协同发展,实施过程中采取的土地、产业、人口、财政等政策对生态效率产生显著影响。基于多源数据和超效率SBM模型,计算了2005~2018年河南省区县生态效率;采用变异系数、标准差椭圆系统刻画了县域尺度和主体功能区尺度生态效率演变规律;利用时空地理加权回归(GTWR)模型分析了主体功能区规划实施策略对生态效率空间异质性的影响。结果表明:(1)河南省生态效率整体处于较低水平,存在明显的空间集聚特征,区县差异随时间的推移有所减少;(2)国家级重点生态功能区平均生态效率最高,其次为国家级重点开发区与省级重点生态功能区,省级重点开发区与农产品主产区平均生态效率最低;(3)土地利用多样化指数、城镇化水平、产业结构、人口密度、地方财政一般支出额等因素对生态效率的影响具有显著的空间异质性,呈现出带状或片状空间分布规律。
Major function-oriented zoning(MFOZ)is an important spatial planning strategy to coordinate the relationship between social economy and resource environment through the classification and governance of territorial space.However,the impact of MFOZ on eco-efficiency is not clear at present.Based on the super-SBM model,standard deviational ellipse,variation coefficient and geographically and temporally weighted regression(GTWR)model,the evolving trends,spatial patterns,aggregation characteristics of eco-efficiency in Henan province from 2005 to 2018 at county scale and major function-oriented zone scale since the implementation of MFOZ were revealed,as well as primary driving forces affecting the spatial heterogeneity of eco-efficiency,in order to provide a scientific basis for optimizing spatial governance.The results show that①the eco-efficiency of Henan province is low and has obvious positive spatial agglomeration,with the difference in eco-efficiency between counties showing a decreasing tendency;②the average eco-efficiency of national key ecological functional zones is the highest,followed by national key development zones and provincial key ecological functional zones,and the average eco-efficiency of provincial key development zones and main agricultural products zones is the lowest;③the effects of land use diversity index,urbanization level,industrial structure,population density,local fiscal general expenditure amount on eco-efficiency exhibit significant spatial heterogeneity,often manifesting in strip or sheet spatial distribution pattern.
