(1) Distribution of stmata of leaves of the trees used for revegetationDistribution of stomata of leaves of 22 species trees used for revegetation in Setouch (Inland See) region was investigation. As a result, all of the tree species investigated has stomata only on the back side of the leaves and none on the front side. It is recognized that some species such as Liriodendron tulipifera and Zelkova serrata changed the distribution of stomata with soil water conditions, on the other hand, some species such as Raphiorepis nnbellata and Pitosporum tobira didn't change the distribution of stomata. This results indicate the difference of the caracteristics of tree species, and it is possible to estimate the soil water condition by the distribution of stomata.(2) Characteristics of the photosynthesis and transpiration of Liriodendron tulipiferaPhotosynthetic rate and transpiration rate of Liriodendron tulipifera were measured in Kagawa University, Kinbuchi Forest Park and Marugame Station Sq … More uare for 2years. Light-saturated photosynthetic rate of the mature leaves showed sround 15 micro-mol CO_2/m^2/sec from May to September, but it dropped down greatly in the drought period of Summer. The tree in Marugame Station Square was planted on the artificial ground above the underground parking and paved with asphalt around the trees, so it is not expected the supply of ground water and infiltration of rain into the soil. This conditions is apt to rise soil drought, so that The tree in Marugame Station Square showed lower photosynthetic rate and transpiration rate and frequently drop down. It is pointed out that one of the problem of the planting on the artificial ground.(3) Characteristics of the photosynthesis and transpiration of Cinnamomum CamphoraPhotosynthetic rate and transpiration rate of Cinnamomum Camphra were measured in Kagawa University, Ritsurin Park and Sakaide Green Belt for 3 years. Light-saturated photosynthetic rate of the mature leaves showed 12 - 16 micro-mol CO_2/m^2/sec from June to Septamber and in winter they showed 1/3 - 1/2 of the level in summer, but in the drought period of summer the photosynthetiv rate dropped down, and the tree that has a poor root system because of compacted soil conditions showed greatly drop down.The photosynthetic rate of 12-16 micro-molCO_2/m^2/sec can be used as an available index for health estimation of Cinnamomum Camphora.

(1)造林树种叶片气孔的分布调查了塞图什(内陆)地区22种绿化树种叶片气孔的分布。因此，所有调查的树种都只在叶片背面有气孔，而在正面没有气孔。一些树种如鹅掌茅和锯缘泽兰的气孔分布随土壤水分条件的变化而改变，而另一些树种如毛果油菜和金针茅则不随土壤水分条件的变化而改变。在香川大学、金步町森林公园和马鲁格玛站Sq…测定了鹅掌柴的光合作用和蒸腾特性。更多的尿毒症持续了2年。成熟叶片的光饱和光合作用速率在5~9月为15微克分子CO2/m2/秒左右，但在夏季干旱时期下降幅度较大。马鲁加梅车站广场的这棵树种植在地下停车场上方的人造地面上，树周围铺设了沥青，因此预计不会出现地下水供应和雨水渗入土壤的情况。在此条件下，土壤干旱容易加剧，导致马鲁加姆站广场的树木表现出较低的光合速率和蒸腾速率，并经常倒下。樟树的光合作用和蒸腾特性在香川大学、Ritsurin公园和Sakaide绿地连续3年测定了樟树的光合作用和蒸腾速率。6~9月成熟叶片的光饱和光合作用速率为12~16微克分子CO2/m~2/s，冬季为夏季的1/3~1/2，夏季干旱时期光合作用速率下降，因土壤紧实而根系状况差的树木下降幅度较大，12~16微克分子CO_2/m~2/s可作为樟树健康评价的有效指标。较少
