The purpose of this study is in identifying the attraction degree of Seonunsan Provincial Park by quantitative analysis. For this, landscape slide test was performed by questionaries. And multiple regression analysis and Factor analysis were performed far identifying the attraction degree of users. The attraction degree of natural resources was evaluated by questionaries about the landscape scene of 120 slides which was pictured at the chief visual corridor So it is considered that tourism route far attracting people into natural characteristic resources should be developed. It is identified once again that factors of $\boxdr$Naturalness$\boxul$,$\boxdr$Uniqueness$\boxul$and $\boxdr$Mysteriousness$\boxul$are important in natural landscape. And 16 explanation variables which explain the attraction degree of viewing landscape were classified as 4 factors. Those were defined as $\boxdr$Ability (FⅠ)$\boxul$, $\boxdr$Season harmony (FII)$\boxul$,$\boxdr$Simplicity (FⅢ)$\boxul$ and $\boxdr$Legibility(FⅣ)$\boxul$. It is identified that the variables of FⅠ, mysteriousness, is a representative image which expresses the characteristics of Seonunsan Provincial Park.

Ecological measurement and biological environment of the Moak Provicial Park surveyed based on the habitat; deciduous broad leaved forest (Quercus mongolica variabilis-Pinus densiflora, Capinus tschonoskii, Quercus Mongolica, Quercus acutissima-Pinus densiflora, and Quercus variabilis), coniferous forest (Pinus densiflora), plantation forest (Pinus rigida), and the other place (pond, lake, rice field, stream, and river). Totally, 1 orders, 4 families, 8 species of amphibians were found at Mt. Moak provincial park. Biodiversity indices of studied region were as follow; richness was 1.270, diversity was 1.775, and evenness was 0.853 in amphibians. 42.1% of amphibians were found in deciduous broad leaved forest, 11.3% in coniferous forest, 1.6% in plantation forest, and 45.0% in the other region.

This experiment was conducted to determine effects of trenching depth on characteristics and yield of tubers in Chinese yam (Dioscorea opposita Thunb). Self-propelled trencher, ‘NF-827H’ produced by KAWABE company, was used for trenching. When trenched, tuber's length and weight were longer and heavier, tuber's shape was better, and marketable tuber yield was remarkably increased than those of conventional plowing and soil preparation by a tractor. The size and yield of tubers were greatly enhanced by trenching in long-tuber variety than that in short-tuber variety. The depth of trenching is recommended to be more than 60cm for short-tuber variety and more than 80cm for long-tuber variety considering the size, shape and yield of the tllbers.

These experiments were conducted to promote the rooting in tea cutting bymeans of several root media, growth regulators, cutting material and cutting condition The results are summarized as follows. The rate of rooting was higher in the softwood than in the hardwood, and the best cutting sea­son was about August 10 in the hardwood, about April 10 in the softwood. The most suitable root medium was the Masato at which the rate of rooting was 71%, 87% each in the softwood and in the hardwood. When growth regulators, such as oxyberon, rootone were sprayed upon the hardwood, the rate of rooting was promoted to 4 - 9 % better than that of no treatment. But such a good effect was not recognized significantly in the softwood.

The Convention on Biodiversity (CBD) recommends that 17% of the land be designated as a protected area to counter global environmental problems. Korea also realized a need to designate protected areas according to the international level and explain the significance of designating protected areas. Accordingly, studies on ecosystem services are required. In Korea, the protected areas are designated as national parks, provincial parks, and county parks by hierarchy under the Natural Parks Act. However, as priority was on political and administrative aspects, research on ecosystem service value evaluation and habitat management were concentrated in national parks, and provincial and county parks were relatively neglected. Therefore, more studies on provincial and county parks are necessary. In this study, habitat quality for Gajisan Provincial Park, where there were few studies on habitat management and ecosystem service valuation, was evaluated using the InVEST Habitat Quality model among the InVEST models. The analysis results were compared with 16 mountainous national parks. The results showed that the habitat quality value of Gajisan Provincial Park was 0.83, higher than that of the surrounding areas. The analysis of habitat quality in three districts showed 0,84 for the Tongdosa and Naewonsa districts and 0.83 for the Seoknamsa district. By use district, the nature conservation district, the natural environment district, the cultural heritage district, and the park village district had the highest habitat quality value in that order. Compared with the existing habitat quality analysis results of national parks, Gajisan Provincial Park showed naturalness at the level of Mudeungsan National Park. These results can be used as objective data for establishing policies and management plans to preserve biodiversity and promote ecosystem services in provincial parks.

This study was carried out to find growth characters and distribution of above and underground in natural crossed population of Paeonia lactiflora Pallas. Sprouting time was 1 April to 15 April, and distribution of stem length ranged from 21 to 80cm, and 3 to 18 in stem number. Distribution of root length ranged from 12 to 59cm, root number per plant was 73 to 4, root yield per plant was highly varied by 37 to 882g, and larger root above 750g was occupied by 7.1%. Paeoniflorin content was 1.9 to 10.29% and plants containing higher paeoniflorin was 14.3%. Root length and yield had highly positive correlation. Root diameter and stem length was also positively correlated.

This experiment was carried out to investigate the effect of rain shelter cultivation on the its quality of safflower. The development and growth of safflower, especially the number of secondary branches per plant was increased by rain shelter. Under the rain shelter started earlier, the seed yield was increased by 95% compared with that of non-shelter condition. The number of plants in a unit area the number of flower buds and seeds per plant and seed weight were increased in rain shelter condition. As those plants were cultivated under the rain shelter, lightness(L) of their seeds was increased but redness (a) and yellowness (b) were decreased.

This experiment was carried out to investigate the effect of rain shelter cultivation on growth characteristic and yield on Paeonia lactiflora Pallas. The sprouting time and flowering time of rain shelter cultivation were 9days and 15days, more quickly than that of field conditions, and stem length and number of stem per plant were many more or larger. The disease occurrence rain shelter cultivation was decreased of rust, anthracnose, powdery mildew and root rot disease compared to field conditions, and leaf spot disease was to similar. The root length, number of root and root diameter were to be good in the rain shelter cultivation. Root color and commercial ratio of rain shelter cultivation were better lighten and improved than field cultivation. Root yield of rain shelter was 2,395kg/10a, this was increased 9% and 27% respectively, compared to 2,201kg/10a, 1,892kg/10a of field A and field B.
