陕西省党家村古村落植物景观调查分析

以陕西省韩城市党家村古村落为研究对象，根据对村落中植物及乡村景观的调查，运用植物丰富度指数、Simpson指数、Shannon-Weinner指数对党家村园林植物进行多样性分析，并通过乡土植物在不同区域的应用频率分析其应用特点，再从植物的景观空间、配置形式及艺术表现分析党家村植物景观的现状。结果表明，党家村古村落植物存在灌木和地被层多样性较低、乡土植物应用频率相对较低、植物景观营造手法较为简单三大问题；提出丰富景观植物、注重乡土植物及优化造景手法的具体改善建议，以期为党家村后续的植物景观建设提供参考。

A Survey of Plantscape of Dangjiacun Ancient Village in Shaanxi

Dangjiacun ancient village, a well-known tourism site in Shaanxi Province was investigated with the emphasis of plantscape. Plant diversity was analyzed by using indices such as plant richness (S), Simpson index (D) and Shannon-Weinner index (H). The native plants application features in different regions were examined by their application frequencies. And the current situations of the plantscape of the village were demonstrated from the aspects of the space, arrangement, and artistic expression. Problems such as lower species diversity in shrubs and ground layers, lower application frequency of native plant species, and simple plantscape design techniques were pointed out. Countermeasures of enriching landscape plants, using native plants more frequently and optimizing the plantscape techniques were put forward to provide a reference for the plantscape construction in the village.
