摘　　要：利用LI-6400便携式光合测定仪对自然条件下淮北相山同一生境中的优势物种构树的光合日进程进行了初步测定,结果表明:构树具有相对较高的净光合速率、蒸腾速率及瞬时水分利用效率,反映了构树对旱生条件具有较强的适应性。Diurnal photosynthetic courses of Broussonetia pupyrifera was measured by Li -6400 under natural conditions in Xiangshan mountain of Huaibei city, Anhui province. The results showed that Broussonetia pupyrifera had relative higher net photosynthetic rate, transpiration rate and water used efficiency, which suggested that Broussonetia pupyrifera had different way to adapt itself to its environments in natural conditions.
