| 内容記述 | The theory of the quantification in the multi-variate analysis has been already applied to the estimation of site index from the sum of estimated quantities of categories of soil conditions and environment factors. This treatise deals with the abbreviate method in the process of calculation of estimated quantities of categories of soil conditions and environment factors for the estimation of site index. Forests which had been picked out as numerical examples are natural pine forest in Central and Southern Shinshu_ and artificial larch forest in Eastern Shinshu. The results of analysis by these data may be summarily illustrated as follows: 1. We shall be able to expect a good accuracy of the estimation of site index by the abbreviate method for the solution of quantities of categories of soil conditions and environment factors. 2. We shall be able to estimate to some extent the relation between site index and soil conditions and environment factors. 3. We can not expect to be able to estimate or predict site index from the sum of quantities of categories of soil conditions and environment factors for the real forest stand. 4. It is necessary to survey closely soil conditions and environment factors in each sampling plot. 5. It is necessary to take more sampling plots in order to get more stable solutions. 6. The site index is suitable for outsider of site, but intensive classification as 2 meter interval is not always necessary. | |||||||||||
