Abstract

This is report on the cover degree,frequency, height, and standing crop of the tall grass type, measurd by the systematic sampling method which applied 44 tall grass type sites in Korea, ten IxIm. sq. were taken each of them, during the interval 69.5-69.10.30.
The present study investigated PH. water content, Humus as the soil element, and warmth index as the climatic elements.
The survey of result is like following.

2. The growing-period of tall frass type is under the great influence of fresh weight of the Korea native grassland by the limiting factors of climatic elements (temperature, precipitation, etc.) And also demolition of the soil formation process, caused by the biotic factor, results in the decrease of the fertility.
3. There is a tendency that the more moderation of the biotic factor is increase. the less SDR,RD, weinght, and height of Miscanthuns are decrease, and on the contrary, community components is increase.
4. Accrding to constancy, sequence of the sort whose treuegrad is high are Pteridium, Artemisia, Arundinella, Lespedeza. And Sasa is distributed in the large forest floor of Quereteum, and it´s in inverse proportion to succession sere of Miscantheum.
5. We could find that amount of production was decrease in proportion to modal-D.S of Miscanthus type grassland.
6. The relations between D.S and RD, and D.S and IGC are positive and negative correlation on modal D.S.
7. We can determine the positive negative ecological distance on typical status of Miscanthus type vegetation as a standard.And ecological status of the Miscanthus type vegetation can be assumed.
8. At the Miscanthus type grassland, the continnum of the succesion sere could be recognized, and we found a remarkable tendency in the fact that the weight ratio of each main herbs showed a curve of increase-peak-decrease according to D.S.And on each site of the modeal-D.S appeared distribution area respectively.
9. In the measurement of the percentage of appearanc site of soil element and of Miscanthus type site, the PH got the highest value at 6.0%, soil content at 5.00%, and Humus at 3.00% respectively.
And soil element and RD had positive and negative corrlation.
10. It´s Seemed that the grassland productivity is deeply related with warmth index, horizontal change and vertical change are considered to be caused by the difference of growing-period.
