The contents of this report are some results of above mentioned studies; as following
1. The general condition of experimental area are shown as Table 1. and Fig. 1.
2. The test-sticks are collected in or near to experimental area, cutted by saw and setted on the litter.
The size of stick: d=±2cm. l=30cm.
