چکیده
به منظور امکانسنجی توسعهی کشت بادام، طبقهبندی قابلیت اراضی منطقه خضرآباد با موقعیت جغرافیایی َ55، ْ53 تا َ20، ْ54 طول شرقی و َ45، ْ31 تا َ 15، ْ32 عرض شمالی با روش تصمیمسازی چندمتغیره بر مبنای شاخص آسیبپذیری زیست محیطی انجام شد. در این روش، شاخص آسیبپذیری زیست محیطی در محدوده هر واحد کاری مشخص شد و پس از تلفیق واحدهای دارای طبقات یکسان، نقشههای نهایی پتانسیل اراضی به مقیاس 50000/1 در محیط نرمافزار Arc View به دست آمد. مطالعات انجام شده نشان داد که 43/22% از کل منطقه مطالعاتی به وسعت 17604 هکتار برای احداث باغات بادام مناسب میباشد. این مناطق عمدتاً در بخشهای کوهستانی و مرتفع جنوبی با شرایط اکولوژیکی و بیولوژیکی مناسبتر قرار گرفت. نتایج این پژوهش نشان داد که به کار بردن شاخص آسیبپذیری زیست محیطی برای طبقهبندی قابلیت اراضی، امکان تفکیک مناسبتر اراضی را برای کاربریهای کشاورزی فراهم میآورد. همچنین، به هنگام انجام طرحهای توسعه کشاورزی و باغداری نتایج این پژوهش، امکان برنامهریزی را برای به حداقل رساندن ریسک و خطر آسیب به منابع طبیعی فراهم میسازد و میتواند در برنامه ریزیهای توسعهای، تعادل بین طرحهای به اجرا گذارده شده و محیط زیست را فراهم کند.

چکیده [English]
To feasibility development of Amygdalus communis cultivation, land capability classification on the basis of Multiple Criteria Decision Making (MCDM) and Environmental Vulnerability Index (EVI) indices was studied in Khezrabad desert area (with 53˚, 55¢ - 54˚, 20' E and 31˚, 45¢- 32˚, 15¢ N), in Yazd province. In this study, the environmental vulnerability index was determined in each work unit; then the final maps of land potential with a 1:50000 scale resolutions were obtained by units with the same class, by Arc View3.2 software. The results showed that 22.43% of the whole studied area (17604 ha) was proper for almond cultivation. This part is located at mountainous and hilly areas. These areas have better ecological and biological conditions comparing to other parts of studied area. According to the results, EVI index was suitable ability for zoning of land capabilities for Amygdalus communis cultivation. The results could be apply for decreasing the risk of agricultural development projects and making balance between development projects and environment according to priorities and zonation of land capability of the area.
