چکیده مقاله :
رویشگاه طبیعی داج که جز شهرستان بم می¬باشد به دليل تنوع گياهي زياد، داراي قابليت بالايي در زمينه گياهان دارويي مي¬باشد. به همين منظور شناسايي و تعيين شايستگي براي كاربري گياهان دارويي اين منطقه هدف اين تحقيق قرار گرفت که بر اســاس روش FAO و بــا بكارگيري سيستم اطلاعات جغرافيايي در محیط نرم¬افزاری Arc-GIS 10.4.1 انجام شد. در این روش طبقـات شايسـتگي برای چهـار طبقـه خوب (S1 ) ،متوسط (S2 )، ضعيف (S3 ) و غيرشايسـته (N ) بر اساس شرایط محدود کننده لحاظ شد. بر اساس نتایج بدست آمده محدود کننده¬ترین عامل محیطی برای برداشت گونه¬های دارویی شاخص اقتصادی تولید است و شاخص اقتصادی تولید بعنوان یک عامل مهم محدود کننده برای شایستگی مخصوصا در جوامع گیاهی قلم-بیابانی (Fourtonia sp) و سیاه¬فژ (Cousinia stocki) محسوب می¬شوند. بطوری که این دو جامعه از نظر برداشت گونه¬های دارویی نامناسب (N ) محسوب می¬شوند و همچنین جوامع گیاهی گیشبرگ (Rhazya stricta) و قیچ (Zygophllum eurypterum) از نظر این شاخص شایستگی ضعیف (S3 ) دارند. طبق این مدل¬سازی، شایستگی سه جامعه گیاهی بادام-بنه (Amygdalus scoparia- Pistacia atlantica)، درمنه (Artemisia sieberi)، بادام (Amygdalus scoparia) متوسط ارزیابی شد که با مدیریت صحیح و برداشت اصولی می¬توانند در بهبود معیشت بومیان منطقه کارساز باشند.
Daj region, which is part of Bam city, has high potential in the field of medicinal plants due to its great plant diversity. Therefore, the aim of this study was to identify and determine the suitability for the use of medicinal plants in this field. This research was conducted based on the method of FAO, 1991 (using Arc-GIS 10.4.1 package). In this method, to determine the suitability classes, the use of rangelands for different classes are considered as four good quality classes (S1), medium (S2), poor (S3) and unsatisfactory (N). The restrictive condition method was also used to determine the final model. According to the results, the most limiting environmental factor for harvesting medicinal species is the economic index of production. According to the results of this study The economic index of production is considered as an important limiting factor for competence, especially for the plant types of Fourtonia sp and Cousinia stocki, so that these two communities are considered unsuitable in terms of harvesting medicinal species and also plant types Rhazya stricta and Zygophllum eurypterum have poor competence in this index, according to this modeling, the competence of three plant communities of Amygdalus scoparia- Pistacia atlantica, Artemisia sieberi, Amygdalus scoparia was assessed as moderate which can be utilized by indigenous individuals to have better livelihood.
