This study was performed to investigate the most suitable environment conditions of Hepatica asiatica on the position, vegetation, weather and soil conditions around Hepatica asiatica habitats.
The survey location were selected at the Anilsa and Daeducksa temple areas of alt. Daeduck and Pukjijangsa temple aera of Mt. Palgong located in Taegu, Korea.
The results are summarized as follows:
1. Vertical distribution area of Hepatica asiatica was ranged from 200m to 500m above the sea level. Most of the habitats faced toward the north and the gradient was about 30 degree.
2. Total species at all the survey locations were 38 woody plants and 56 herbaceous plants. 98.4 of total woody plants was deciduous broad leaved tree. Dominant species was Indigofera kirilozoii and Lespedexa maximouricxii var. tomentella at the Anilsa temple area, Stephanandra incisa and Lindera erythrocarpa at the Daeducksa temple area and Lespedeza maximozvicxii and Viburnum punctatum at the Pukjijangsa temple area.
3. Monthly average air temperature was ranged -5℃∼5℃ in winter, 18℃∼24℃ in summer and 10℃∼15℃ in spring and autumn.
4. Light intensity in the growing place of habitat was 10,000lux from Nov. to March, 4,000lux from Apr. to May and 1, 2001ux from June to September.
5. Soil acidity at the survey location was pH 5.1∼5.3. Total nitrogen contents, organic matter, P₂O_5, K, Ca, Mg, Na and CEC were 0.07%, 21.1%, 38ppm, 0.83m.e/100g, 8.1m.e/100g, 3.8m.e/100g, 0.56m.e/100g and 20.4m.e/100g, respectively. Soil texture was sandy loam and average soil moisture content was 23.3% in March and 50.2% in July.
