A study on the determination for degree of green naturality in Suncheon city was conducted as the part of the project for investigation of green capacity, Cheonnam from 1989 to 1991. Through the determination for degree of green capacity in Suncheon city, the totality of green nature in the surveyed area was transformed to degree of green naturality(DGN) which is one of the barometers indicating the extent of destruction of natural green vegetation. The whole area of Suncheon city was divided into one-kilometer squares, total 90 meshes. Each of these squares meshed was given a rating in the degree of green naturality in vegetation. These ratings are an measure of how much nature remain intact. They also show the extent to which nature has been destroyed by man. The findings on this point constitute a principal feature of the survey. The survey was carried out in a belief that quantitative measurement are needed to learn about the impact on the human living environment. Four different grades of green naturality ; DGN 1, 2, 6 and 7 have been registered in Suncheon city. Prominent DGN was 2, which occupied 36.7% of the survey area. Average of degree of green naturality was recognized as 4.12 in whole area. The volume of vegetation existing in Suncheon city was estimated 347,690 tons, and vegetation out-put was estimated 72,630 tons in one year. The numbers of protected tree investigated in Suncheon city were 4 provincial tree, 11 city-county tree and 41 village tree, total 56 protected tree.

The vegetation, which is based on vascular plants, in the vicinity of the Po^sung-gang dam was investigated phytosociologically over 13 times on 57 points from November, 1991 to July, 1993. Species composition, live form, and community structure of the flora, species diversity, and similarity index were determined, and the profile diagram of plant community and actual vegetation map were constructed. Vascular plant flora in the surveyed area was 34 orders, 92 families, 247 genera, 340 species, 1 subspecies, 44 varieties and 2 forma, in total 387 kinds. The composition of life form was classified into Ch-D_1-R_5-e type. Vegetation was classified into coniferous forest and deciduous broad-leaved forest. Coniferous forests were composed of the communities of Pinus densiflora and P. thunbergii as the natural forest, and P. rigida community, Chamaecyparis obtusa community and other 15 mixed forest communities as artificial forest. Deciduous broad-leaved forests were extensively composed of natural forest such as Quercus acutissima community and Q. aliena community, and artificial forest such as Alnus japonica community, C. crenata community and Robinia pseudo-acacia community, and other 6 mixed forest communities. The communities of Camellia japonica and Miscanthus sinensis var. purpurascens were observed on a small scale in the surveyed area. Species diversity index was 1.105, in coniferous forest and 1.118 in deciduous broad-leaved forest. Similarity index between the two communities was 0.555, which means those communities are remarkably different from each other in species composition. Pterophyta quantity(Pte-Q), which is 0.68, was lower than that of national average, 1.68, while urbanization index measured as 2.37 was higher than that of national average, 9.9. The vegetation of vascular plants in Po^sung-gang Dam was coincided with that of the southern area of the Korearn peninsula, in distribution types of family or genus. It was to be noted that a natural community of Scirpus radicans which is generally believed to be distributed in northern area was found in this surveyed area.
