چکیده

       منطقه حفاظت شده کالمند بهادران با مساحتی حدود 255 هزار هکتار در فاصله 30 کیلومتری شهرستان یزد و در جنوب‌شرقی شهرستان مهریز با مختصات جغرافیایی ¢00 و °31 تا ¢40 و °31 عرض شمالی و ¢15 و °54 تا ¢20 و °55 طول شرقی قرار دارد. پوشش گیاهی منطقه به روش  فیزیونومیک - فلوریستیک مورد بررسی قرار گرفت. برخی از خصوصیات خاک بر اساس روش‌های معمول مورد سنجش قرار گرفتند و داده‌های حاصل به روش PCA آنالیز شد. نتایج نشان ‌داد که ارتباط ویژه‌ای بین جوامع گیاهی مختلف و خصوصیات خاک وجود دارد. مهمترین عوامل در تفکیک این جوامع گیاهی هدایت الکتریکی، اسیدیته، بافت، کربن آلی و نسبت جذب سدیم می‌باشد. به‌طور کلی هر جامعه گیاهی با توجه به شرایط زیستگاه، نیاز‌های اکولوژیک و دامنه بردباری متفاوتی با عوامل محیطی و مشخصات خاک دارد.

چکیده [English]

The Bahadoran Kalmand protected area with an area of 255000 hectares is located at about 30 km Yazd township and in the southeastern township of Mehriz with geographical coordinates of 31° 00¢ to 31° 40¢  North latitude and 54° 15¢ to 55° 20¢ East longitude. The vegetation cover was studied using the physiognomic-floristic method. Some soil characteristics were evaluated based on conventional methods and data were analyzed by Principal Component Analysis (PCA) method. The results showed that there was a special relationship between different plant communities and soil characteristics. The most important factors in separating these plant communities were electrical conductivity, acidity, texture, organic carbon, and sodium adsorption ratio. In general, in regard to habitat conditions, each plant community has different ecological needs and tolerance range with environmental factors and soil characteristics.
