摘要
土地利用功能之间存在复杂的权衡与协同关系,协调好生态脆弱贫困区土地利用功能冲突问题是服务生态文明建设、国土空间优化开发的重要价值体现。文章以张家口市为研究区域,从经济、社会和生态三个维度构建土地利用功能分类与指标体系,融合多源数据,采用综合评价法、双变量空间自相关法、面积占优法等测度1990—2015年土地利用功能及其权衡/协同关系演变特征。基于此,划分土地利用功能区,提出相应的优化路径。结果表明,土地利用经济与社会功能以协同型关系为主,多发生在中部洋河谷地和东部山区。生态与经济功能的权衡型与协同型关系交替居于主导地位,生态与社会功能由协同型关系转为权衡型关系为主导。生态与经济功能及与社会功能权衡型关系主要分布在中部洋河谷地和东部山区,协同型关系多发生在坝上高原。将张家口市国土空间划分为生态保护区应以保护生态为主;城镇发展核心区应以优化产业布局和城镇体系为主;城乡优化发展区应以发展都市农业、建设特色小城镇为主;农业生产区应以发展生态特色农业为主。
It exists the extremely complex trade-off and synergy relationships on land use functions(LUFs).Coordinating the conflict of LUFs in ecologically fragile and poverty areas plays an important role in serving ecological civilization construction and territorial space optimization.Taking Zhangjiakou City in Hebei Province as research area and based on multi-source data,this study establishes LUFs classification and index system from"economy-society-ecology"dimensions,measures LUFs and their trade-offs&synergy relationship characteristics from 1990 to 2015 adopting the comprehensive evaluation method,bivariate spatial autocorrelation method and area predominance method.Based on the above,this paper makes out the land use function zonings and proposes corresponding optimization paths.The results show that,in 1990-2015,the relationship between land use economic and social functions were mainly synergistic,which mainly occurred in the Yanghe valley and eastern mountains.As for economic and ecological functions,the trade-offs relationship was dominant in 1990 and 2015;while the synergistic relationship was dominant in 2000.In terms of social and ecological functions,the synergistic relationship was prevailing in 1990,while the trade-offs relationship played a leading role in 2000 and 2015.The trade-offs relationship between economic and ecological functions,social and ecological functions mainly occurred in the Yanghe valley and eastern mountains,while their synergistic relationship mainly distributed in Bashang area.Accroding to the above analysis and combined with the actual situation,Zhangjiakou City is divided into four zoning types as follows:the ecological protection zone which reflects the dominant function of ecological conservation and should give priority to protecting ecology,urban development core zone which embodies the dominant function of economic development and should focus on optimizing industrial distribution and urban systems,urban and rural optimization development zone which presents the dominant function of social security and should put a high priority on developing urban agriculture and characteristic towns,agricultural production zone which demonstrates the dominant function of food production and should focus on developing ecological and featured agriculture.
