【摘要】：土地节约集约利用是现今城市可持续发展必要的措施,节地技术与模式的发展,又是节约集约用地不可缺少的环节。合理的配套措施、完善的用地机制,有效促进城市土地高效利用,成本、资源得以节约。推行节地模式是实现城镇建设可持续发展的有效之路,不同县市对节地模式有着不同适用性,分析不同类型城市节地模式特征,为典型案例的推广移植做好铺垫。本研究通过选取60个典型节地模范县市作为研究样本集,综合选取6个核心指标和4个扩展指标,构建聚类分析指标体系;利用层次聚类分析法和k-means聚类法对比分析聚类结果,对聚类结果进行定量、定性和空间分析,总结归纳同一类别节地县市的共性特征和特有特征,在此基础上为每一类别节地模式系统命名;最后,随机挑选5个县市作为实例进行实证分析,验证聚类结果节地模式的适用性。主要研究结果如下:(1)构建节地模式聚类分析指标体系。以依托项目6个核心指标为主要指标,参照文献研究成果,总结扩展4个核心指标,共10个指标数据建立节地模式聚类分析研究指标体系,为节地技术与模式的后续研究提供指导性依据。(2)选取双约束Euclid距离代替传统距离计算量,层次聚类法与k-means聚类法相互验证对比聚类结果,所得结果吻合。聚类系统对60个县市自动划分7个类别,依据地域空间的集群性,7类县市分成11种节地模式。(3)对所建立10个指标选取6个指标,进行均值趋势对比,定量分析每一类别城市表现特征;通过案例库系统总结典型县市节地模式,作为节地模式三级命名依据;根据7类县市在地域空间上聚集分布状况,分析城市聚类的空间特性。(4)梳理总结全国县市节地模式,细分为时序优化、空中拓展、地下开发、集中布局、产业升级、闲地清理、旧地改造、新地开发8种模式。节地模式命名体系采用三级命名规则,对11个节地模式类进行系统命名,建立命名体系表。(5)随机挑选的5个县市进行实证分析。结果表明,有4个县市节地模式是适用于所总结11种节地模式,命名原则导致1个县市地域上、县市特征上不符合所属类别命名特征,不属于11种节地模式。节地模式研究成果,依然具有全国适用性。
[Abstract]:Land saving and intensive utilization is a necessary measure for the sustainable development of modern cities. The development of land saving technology and mode is an indispensable link of saving and intensive land use. It is an effective way to realize the sustainable development of cities and towns, and different counties and cities have different applicability to the land saving mode, which can effectively promote the efficient use of urban land and save the cost and resources. This paper analyzes the characteristics of different types of urban land saving models, and lays the groundwork for the popularization and transplantation of typical cases. This study selects 60 typical model counties and cities as the sample set, and synthetically selects 6 core indicators and 4 extended indexes. Construct the index system of cluster analysis, use hierarchical cluster analysis and k-means clustering method to compare and analyze the clustering results, analyze the clustering results quantitatively, qualitatively and spatially, sum up and sum up the common characteristics and unique characteristics of the same type of counties and cities. Finally, five counties and cities were randomly selected for empirical analysis. The main research results are as follows: 1) construct cluster analysis index system of saving land pattern. Based on the six core indexes of the project as the main index, and referring to the research results of literature, summarize and expand four core indicators. Ten index data are used to establish the index system for cluster analysis of saving land mode, which provides a guiding basis for the further study of land saving technology and mode. (2) double constrained Euclid distance is chosen to replace the traditional distance calculation. The hierarchical clustering method and k-means clustering method verify and contrast the clustering results, and the results are consistent. The cluster system automatically divides 60 counties and cities into 7 categories. According to the regional spatial cluster of seven counties and cities are divided into 11 types of land saving model. (3) the 10 indicators were selected to select 6 indicators, the mean trend of comparison, quantitative analysis of each category of urban performance characteristics; Through the case base system summarizes the typical county and city festival land pattern, as the saving land pattern three level naming basis; according to the seven kinds of counties and cities in the regional spatial aggregation distribution situation, analyzes the city clustering spatial characteristic.) combs and summarizes the national county and city saving land pattern. Subdivided into 8 patterns: time sequence optimization, air expansion, underground development, centralized layout, industrial upgrading, idle cleaning, old land transformation and new land development. The systematic naming of 11 section land pattern classes and the establishment of naming system table. 5) the empirical analysis of 5 counties and cities randomly selected. The results show that 4 counties and cities are suitable for summing up 11 land saving models. The nomenclature principle leads to the fact that the characteristics of one county and city do not accord with the naming characteristics of its own category and do not belong to 11 land saving patterns. The research results of the land saving model are still applicable to the whole country.
