Species diversity, edaphic and geological rock properties were investigated in the Tokatli Canyon. Quercus infectoria-Platanus orientalis was identified as the plant community with the highest species diversity and richness. High concentrations of N $${\text{H}}_{4}^{ + }$$ and N $${\text{O}}_{3}^{ - }$$ were found in moderately sloping areas in the north-east in the Tokatli Canyon. Available P contents tend to increase towards the Mediterranean communities. Arbutus andrachne-Cistus creticus plant communities, found in the study area (especially on central and higher slopes of the canyon) are an example of Mediterranean relict groupings formed by Mediterranean plants. In Canonical Correspondence Analysis (CCA) available P, pH, K+, Mg++, EC and N $${\text{O}}_{3}^{ - }$$ in the soil and TiO2, Al2O3, MgO and K2O in the rock are the factors affecting species diversity and distribution in the Tokatli Canyon area.

岩石化学和生态因素对土耳其托卡特利峡谷植物多样性的影响

对托卡特利峡谷的物种多样性、土壤和地质岩石特性进行了调查。Quercus infectoria-Platanus orientalis 被确定为物种多样性和丰富度最高的植物群落。在适度倾斜的地区发现了高浓度的 N $${\text{H}}_{4}^{ + }$$ 和 N $${\text{O}}_{3}^{ - }$$在托卡特利峡谷的东北部。可用磷含量趋向于向地中海社区增加。在研究区（特别是在峡谷的中部和更高的斜坡上）发现的杨梅-岩蔷薇植物群落是地中海植物形成的地中海遗迹群的一个例子。在典型对应分析 (CCA) 中，土壤和 TiO2、Al2O3 中可用的 P、pH、K+、Mg++、EC 和 N $${\text{O}}_{3}^{ - }$$，
