摘要
景观特征评价是当前中国城镇化背景下识别地域景观特征、防止景观同质化、促进景观保护与发展的一种有效手段。本研究基于景观的自然组成要素及其空间分布格局特征，利用GIS空间分析和多种数量统计分析手段对北京市海淀区景观进行了定量聚类分析，识别出46种三级景观特征类型、15种二级景观特征类型和5种一级景观特征类型，并从景观分割指数、斑块密度和景观形状指数3个方面对一级景观特征类型斑块的空间分布特征进行了评价。结果显示，距城市中心10～12km处是城市景观与乡村景观的交错带；超过12km则开始出现彼此镶嵌的田园景观与乡村景观特征；当超过32km时，山林景观则成为主导特征；而休闲景观则孤立且均匀分散在研究区各处。
Landscape character assessment is a useful tool which can identify regional landscape character, prevent landscape homogenization, and promote landscape protection and development on the background of urbanization in China. According to natural elements and their spatial pat- tern of a landscape, this study quantitatively identified different landscape character types in Haidian District, Beijing by using a cluster analysis based on GIS and several other technologies. 46 types of third-grade landscape classification, 15 types of second-grade landscape classification and 5 types of second-grade landscape classification were identified. The spatial distribution char- acters of 5 first-grade landscape types were assessed using indicators of landscape division index, patch density and landscape shape index. The results showed that there was an overlapped zone of urban landscape and rural landscape 10-12 km away from the city center. It appeared a land- scape mosaic of rural landscape and pastoral landscape when the distance was beyond 12 km from the city center, while a mountain landscape was dominated when the distance was beyond 32 km. Leisurable landscape distributed separately throughout the study area.
