2007—2017年三亚城市景观空间格局动态特征及驱动因素分析

应用2007—2017年期间4个时间点的遥感影像数据，选取典型景观格局指数，对三亚市的景观空间格局动态特征进行分析，探求其驱动因素。研究表明：近十年来，三亚市内同种土地利用类型的空间聚集程度降低，空间分布逐渐趋向于分散，不同类型的土地之间相互融合度较高，形状趋于复杂化，景观类型分布趋势呈均衡化，景观的破碎化程度加强，景观复杂程度增高，土地利用的丰富程度逐渐加强。通过驱动因素分析，国家政策的导向、城市总体规划的实施、产业结构调整及自然环境的变化是影响三亚城市景观空间格局变化的主要驱动因素。

Analysis of Dynamic Characteristics and Driving Factors of Sanya Urban Landscape Spatial Pattern from 2007 to 2017

Using the remote sensing image data at four moments of a day from 2007 to 2017 and the typical landscape pattern index, the dynamic characteristics of Sanya landscape spatial pattern were analyzed and the driving factors were discussed. The results showed that in the past ten years, the spatial conglomeration of the same land use types in Sanya decreased, the spatial distribution tended to be decentralized, the integration of different land types were relatively high. The shape became more complex and the distribution of landscape types tended to be balanced. The degree of landscape fragmentation and complexity were high, the richness of land use was gradually strengthened. By analyzing the driving factors, the orientation of national policies, the implementation of urban master planning, the industrial structure adjustment and the change of natural environment were the main driving factors influencing the change of Sanya landscape spatial pattern.
