植物群落空间特征与感知的关系研究

The Relationship Between Spatial Characteristics of Plant Community and Visitor Perception

以福州市城市公园中21块不同类型的植物样地作为研究对象,选取样本植物群落空间面积的大小、覆盖度、围合度和D/H作为植物群落空间特征指标,以SD法获得21块样地的游客感知结果,并现场测量其空间特征量,最后通过相关性分析探寻植物群落空间特征与游客感知之间的关系。结果表明:不同的空间特征值与心理感知量存在着一定的相关性,但相关性大小各不相同,在空间尺度特征值中,底面积仅与1个感知心理量有关,覆盖度、围合度、D/H 3个空间特征均与4个感知心理量均相关;从所有的具有相关性关系的空间尺度特征值与感知量来看,D/H与亲近的-疏远的这对感知量的相关性最强,而D/H与有趣的-无趣的这对心理感知量的相关性最弱。将植物空间特征值与人们的心理感知量进行相关性分析和回归分析,得出相应感知的临界值以及与尺度指标的变化关系,这些临界值从量化的角度为人们在植物空间营造时提供具体的数据,使得人们对植物空间特性的营造更加准确。

Taking 21 pieces of plant community in urban parks of Fuzhou as a study object, and floorage, cov-erage degree, enclosure degree and D/H of each sample were selected as the spatial characteristic of plant commu-nity. Obtain the perception results of 21 samples by SD method and on site measurement to obtain the spatial char-acteristic values. Then, explore the relationship between the spatial characteristics of plant community and the visi-tor perception with the correlation analysis. The results showed that the spatial characteristic associated with visitor perception, but different spatial characteristics had different influence in different perception of adjectives. The floorage only had influence in a couple adjectives, coverage degree, enclosure degree and D/H had influence in 4 couple of adjectives. From all the correlation relationship between amount of spatial characteristics and perception, the relationship between D/H and close-distant is the most relevant, D/H and interesting-boring is the weakest. Making relativity analysis and regression analysis between the value of plant community spatial characteristic and perception, obtain the critical value of perception and the relationship between the value of perception and plant community spatial characteristic. These critical value and the relationship in the plant space will provide concrete data from the perspective of quantitative, makes the creation of plant space more accurate.
