Abstract
本調査는 北濟州郡의 관음寺(海拔 約 700m)를 中心으로 攪亂壓이 均質하게 加해진 A. B. C.地所에서 각각 (1x1)m 크기의 Quadrat로 20개式 標集하였다.
調査形質은 頻度, 草高, 莖數, 現存量을 測定하여 積算優占度로 群落型을 決定하였다. 調査는 1968年 6月 22日∼26日까지 하였다.
調査結果는 다음과 같다
① A. B. C 地所에서 植生遷移는 生重量을 指標로 하였을 때 Fig.2와 같다.
②攪亂壓이 甚하여짐에 따라 억새型草地→고사리型草地→잔뒤型草地로 移行하는 系列이 뚜렷이 나타났다.
③ Fig.2에서 群落型 사이에는 相關關係아 있었다.
④ 3群落型(A.B.C.地所)의 構成種의 量에 현저히 差가 있었다.(Table 1)
⑤ 3群落型에서 全生重量은 A>B>C로 낮아지고 現存量은 억새가 A>B>C인데 反하여 고사리, 禾本類, 콩科植物, 灌木類 및 其他草種群은 A⑥ 群落型과 草種 사이의 관계는 出現頻度의 類型으로 4-group를 類別할 수 있었다. (fig. 3)
⑦ A. B. C. 地所의 各群落型에서 出現草種과 出現頻度로 遷移過程에 따라 出現草種의 增感이 있었다.
⑧各群落型에서 階層構造와 現存量과의 關係를 보았다. (Fig. 5) ? 出現하는 草種數는 下層에 많으나 現存量에서 優占種은 높은 値를 나타냈다.
以上의 結果에서 제주도의 草地는 攪亂壓의 作因으로 草種相互間에 遷移系列에서 Competition 現象이일어나고 있음을 確認할 수 있었다.
This survey has been conducte by sampling 20 pieces of 1 squaremeter Quadrat each from the sites A, B, and C whose surface Disturbance was applied to equally, and those sites are located in the neighborhood of the temple Kwan-um-sa in Cheju island approximately 700 meters high at sea level.
Geology (the nature of the soil) has been estimated by measuring frequncy, height number of stem and standing crops on the sites and the community type was obtained by summed dominace ratio.
This experiment had been made made from June 22 to 25, 1968. The results as are following.
1) Plant Succession at the sites A,B, and C is shown in (Fig. 2) when fresh weight is used as an index to it.
2) Biotic pressures are intensive, the succession sere goes as following:
Miscanthus type→Pteridium type→Zoysia type
3) The relationships among those community types are shown in Fig.3.
4) Those communities composed of three, types show remarkable differences in the quantity of the Plants (Table 1).
5) The total quantity of fresh weight in three community types has decreased from the greatest to the smallest in the following order:
A→B→C
The above tendency has reversly decreased with the case in standing crop, Miscanthus and other types of Vegetations (Table 2)
6) The relationship between the community type and vegetation has been classified into four groups accrding to the frequency of their appearance (Fig. 3).
7) The appearance of the vegetation in each community types has increased and decresed in quantity, in proportion to it´s frequency and transition.
8) The relation between the structure of stratum and standing crop has been confirmed in each community types.
According to the result of above articles, the phenomenon of competition in succesion sere among different vegetation on another has been confirmed according to the disturbance in the grassland in Cheju island.
