摘　　要：以杭州市为例,基于多时相遥感影像数据,采用等扇分析、扩展强度指数和重心转移等定量测度方法,分别获取2000—2015年建设用地增长规模、强度和方位的阶段性特征。结果表明:①东、西两翼为增长规模热、冷点地区,全域增长速率经历由低、中速向高速的阶段性转变;②东南、东北部增长强度显著上升伴随西北、西南部持续走低,全域增长格局经历由非均衡、稍均衡到均衡的阶段性转变;③全域增长方位经历由钱塘江以西的主城单核心主导向跨江以东的多中心组团结构的阶段性转变。在此基础上,将用地增长规模同扩展强度的热、冷区域进行空间叠加,获取城市空间增长的四种关联模式;基于多部门空间政策数据,分析不同政策类型对相应关联模式的影响效力。最后得出空间政策对空间增长的作用绩效体现在影响增长形态、调控增长时效和转变增长阶段三个方面。In China′s rapid urbanization process, the spatial planning policy has become the leading factor influencing urban space growth. Take Hangzhou for example, this paper processes stage characteristics of growth scale, intensity and orientation of construction land using tools of the sector analysis, the expansion intensity index and the centroids through temporal remote sensing image data of rural and urban construction land. The results show that： ①The east and southwest are the hot spot and cold spot in increment, and the increase speeds of construction land in three periods are of low-middle-high. ②The intensity of northeast and southeast is significantly increased along with the falling of the northwest and the southwest, and the overall growth pattern of the whole region is changed from unbalanced to slightly balanced to balanced.③The growth orientation of the whole region is transferred from the west to the east of Qiantang River, from the main city single core to multi-center group structure. Next this paper concludes four spatial growth modes based on spatial superposition of land growth scale and land expansion. Related with the multi-sectoral spatial planning policy, the paper analyzes the effect of different policy types on the corresponding correlation modes. Finally, it concludes that the effect of spatial planning policy on spatial growth is reflected in three aspects： influencing growth pattern, regulating growth prescription and transforming growth stage.
