본 연구는 자연형 도시공원 생태자원의 효율적인 보전관리를 위한 기초자료를 제공하기 위하여 식생의 자연성 평가를 실시하였다.도시식생의 자연성 평가를 위하여 전형적인 중ㆍ소도시인 익산시의 5개 자연형 도시공원을 연구 대상지로 선정하였으며,자연성 평가를 실시한 결과는 다음과 같다.1. 익산시 5개 도시자연공원의 식물상은 84과 208속 261종 1아종 3품종 34변종의 총 299종류로 조사되었다.2. 익산시 5개 도시자연공원에 분포하는 식물들의 생활형의 특징은 H-D4-R5의 유형으로 나타났고 생육형에서는 직립형이우세하였다.3. 생활형 스펙트럼을 분석한 결과 M(소형지상식물): 20.0%±1.0%, N(미소지상식물): 10.2%±1.5%, E(착생식물): 2.5%±1.0%, Ch(지표식물): 5.2%±0.8%, H(반지중식물): 22.3%±2.5%, G(지중식물): 9.6%±1.1%, HH(수생식물): 4.5%±0.8%, Th(1년생식물):27.3%±3.7%로 나타났다.4. 식생 자연성 평가에서 III등급인 배산을 제외한 4개 도시자연공원은 IV등급이다. 전체적으로 익산시 주요 도시자연공원의자연성은 높지 않은 것으로 나타났다.

The purpose of this research is to evaluate the naturalness of vegetation to offer fundamental data for the efficient preservation and management of the ecological resources in natural urban parks. For this study, 5 natural urban parks were selected in Iksan city, a typical small and medium-sized city. The outcomes of the evaluation performed may be concluded as follows: 1. The flora of 5 natural parks were found to be composed of 84 families, 208 genera, 261 species, 1 subspecies, 3 forma, and 34 varieties or 299 taxa in total. 2. On the characteristics of this survey, life form were shown to be of the H-D4-R5 types and erect forms were superior in their growth type. 3. The analysis of the life form spectra was shown to have M (Microphanerophytes): 20.0%±1.0%, N (Nanophanerophytes): 10.2%±1.5%, E (Epiphyten): 2.5%±1.0%, Ch (Chamaephytes): 5.2%±0.8%, H (Hemicryptophytes): 22.3%±2.5%, G (Geophyte): 9.6%±1.1%, HH (Hydatophytes): 4.5%±0.8%, and Th (Therophytes): 27.3%±3.7%. 4. Except for Baesan park which was rated to have grade III naturalness of vegetation, 4 other parks belonged to grade IV. In sum, the urban natural parks of Iksan city were found to have low naturalness.
