| چکیده | ||
| محققین و گروههای هدف مطالعه کننده پوشش گیاهی به دنبال دانستن این سوال هستند که استقرار و پراکنش تیپهای پوشش گیاهی و جامعههای گیاهی یک حوضه آبخیز بر مبنای چه شاخصهایی زمینی صورت میگیرد وکدامیک از اشکال اراضی بهتر میتواند مرز و محدوده هر تیپ یا جامعه گیاهی را تعیین نماید؟ بر پایه دو سوال مطرح شده، حوضه آبخیز گردنه قوشچی در استان آذربایجان غربی و مشرف به دریاچه ارومیه به دلیل حفظ پوشش گیاهی بومی خود و قرق منطقه انتخاب و نقشههای پوشش گیاهی، ارزیابی اراضی، زمینشناسی، خاکشناسی، ژئومورفولوژی و واحدهای همگن بر مبنای روشهای علمی و پایش میدانی با دقت و صحت کامل تهیه گردید. جهت تطبیق، توصیف و پیشبینی دقیق تیپهای پوشش گیاهی با اشکال مختلف اراضی از روش آماری رگرسیون لجستیک چندجملهای استفاده شد. نتایج پژوهش حاضر نشان داد که واحدهای همگن با مقدار کمّی 432/0 بیشترین تاثیر و ژئومورفولوژی، زمینشناسی و خاکشناسی با مقادیر کمّی 389/0، 351/0 و 156/0 در رتبههای بعدی میزان تطبیق قرار دارند. لذا شیب، جهت و ارتفاع (ویژگیهای فیزیوگرافی حوضه آبخیز) نقش مؤثرتری در توزیع پوششهای گیاهی دارند و به عنوان بهترین روش جهت مرزبندی و انطباق مرزهای پوشش گیاهی قبل از پایش زمینی میتواند به عنوان نقشه پایه در مناطق نسبتاً کوهستانی و دارای پستی و بلندی مورد توجه قرار گیرد. | ||

| چکیده [English] | ||
| Researchers and target groups studying the vegetation are seeking to answer the question “what ground indicators determine the establishment and distribution of vegetation types and vegetation communities of a basin and which landforms can best determine the boundaries of each plant type or community?”. In this regard, the Gardaneh-Ghooshchi basin, overlooking the Urmia Lake in West Azarbaijan Province was selected. Vegetation cover map, land capability evaluation map, geology map, soil map, geomorphology map, and land units map, were precisely and accurately generated based on the technical methods and field surveys. The multinomial logistic regression method was used to compare, describe and accurately predict vegetation types with different landforms. The results showed that homogeneous units with a quantitative value of 0.432 had the highest impact, followed by geomorphology, geology, and soil with quantitative values of 0.389, 0.351 and 0.156, respectively, in the next rank. Therefore, slope, aspect, and elevation (physiographic characteristics of the basin) have a more effective role in the distribution of vegetation, which could be used before ground monitoring as a baseline map in mountainous areas. | ||
