    The environment is deteriorating on a long-term basis in the Ejina River Basin in Inner Mongolia, China as a result of a water shortage. The shortage was caused by increased water use by industries and agriculture after 1992 along the upper part of the Ejina River. In 2002, the Chinese National Water Resource Agency instituted a water sharing plan which resulted in more water being released downstream to a region including the Kyoen Delta. The repartition will have an effect on vegetation increase in the Kyoen Delta area.

    In order to develop the original long-term cutting age management standard of Sugi (Cryptomeria japonica) plantaions in Nagasaki prefecture, site index curves and taper tables of Sugi plantations were created. 1) Site idex curves were revised up after 40-50 years on stand age, and rate of height growth was not decreased remarkably. 2) On the average relative stem curve, the determination coefficient of polynomial expression was 0.9799. 3) The new taper tables could be applied to trees whose height from 15 to 31 m and DBH from 15 to 50 cm.
