%X 以西安世博园为调查对象，应用景观生态学原理对景区景观要素进行分类，选取多样性指数、优势度指数、均匀度指数、斑块形状指数、分离度指数、分维度指数、破碎度指数及廊道密度等指标进行调查分析。结果表明：西安世博园整体景观格局基本完善，各大功能区景观要素差异显著，区域内景观群落丰富。主景区水体（30.08%）和建筑（21.80%）面积占据主导地位，植物景观相对较少，其中密林斑块（3.61%）占比最小。在景观构架与区域功能的协调性、绿地空间的营造、群落结构和树种组合的合理性等方面存在不足之处。提出西安世博园绿地景观格局优化策略，构建水域区的特色生态景观，强化创意岛的主题文化，改善游乐场的植物造景功能，注重园区路网绿道系统的植物景观优化。<br>Taking Xi’an Expo Park as research object, landscape elements in the park was classified by applying the principles of landscape ecology. Indicators related to landscape assessment were surveyed, including indices of diversity, dominance, evenness, patch shape, separation degree, fractal dimension, fragmentation, and density of corridor. The results showed the park was basically in line with the demand, and significant differences were found in landscape elements in major functional areas, and landscape types of community in the area were rich. The park were dominated by scenic water (30.08%) and buildings(21.80%). Areas of plantscape accounted relatively small proportion, and flourish hurst(3.61%) occupied the smallest. Some problems existed in the coordination of landscape construction, regional function, construction of green space, the rationality of community structure and species composition were found. Optimization strategies were proposed: constructing the ecological characteristics of water area, strengthening the theme culture of Chuangyi Island, improving the function of plant landscape of amusement of park, optimizing the corridor of approach system
