A STUDY ON THE CURRENT STATUS OF 4 SPECIES OF INDOOR DECORATIVE PLANTS IN NARA CITY

Abstract

 In this study, 4 species of indoor decorative plants, which were considered to be widely observed in the city, were selected as research subjects, and the growth distribution was investigated in three areas in Nara city. Then, the distribution characteristics of each species were grasped by comparing them by region and land use type. Analyzing the growth distribution map and comparing the plant density, the area around Shin-Omiya Station was the highest at 8.62 plants/ha. The plant density was markedly lower at 1.56 plants/ha around Tomio Station and 0.25 plants/ha around Narayama Station. In the comparison by land use type, all plant species showed the highest density in residential areas around Shin-Omiya Station. When comparing the age of the buildings, it was found that plants were concentrated in the area where there were many houses more than 30 years old. Among the plant species, Crassula ovata was the most common, and the result was different from that of Chlorophytum comosum, which was the most common in Osaka and Hyogo Pref..
