Abstract

Assessment of desertification hazard in Abu-Ghoveyr Plain, Dehloran, Ilam Province of Iran Abstract: The present study aims to evaluate the desertification hazard and determine the effective criteria affecting desertification in Abu-Ghoveyr Plain in Ilam Province, using the 9 criteria Iranian Model of Desertification Potential Assessment (IMDPA). To this end, first, work units maps (geomorphologic facies) were created using slope, geology, and land use maps. Using this method, work units were considered as the main unit of desertification and a map was generated for each index according to assigned weights, such that the qualitative map of the desired criteria were obtained using the geometric mean of indicators. Then, through integration and determining the geometric mean of layers obtained from criteria and finally classification of the obtained maps, map of the current status of desertification in the studied area was prepared. The obtained results indicated that 31.67% of the area was in the medium class of desertification (II) and 68.33% belonged to the intense class (III).

伊朗伊拉姆省Dehloran Abu Ghoveyr平原沙漠化危害评价

摘要:利用伊朗IMDPA沙漠化潜力评价模型(IMDPA)，对伊朗伊拉姆省阿布-古维尔平原的沙漠化危险性进行评价，并确定影响沙漠化的有效指标。为此，首先，使用斜坡、地质和土地利用图创建了工作单元图(地貌相)。该方法将工作单位作为荒漠化的主要单位，并根据分配的权重对每个指标生成地图，从而利用指标的几何平均值获得所需标准的定性地图。然后，通过对判据得到的层数几何平均值进行整合和确定，最后对得到的地图进行分类，绘制出研究区沙漠化现状图。结果表明:沙漠化中度(II)占31.67%，重度(III)占68.33%。关键词:分类、模型、标准、植被覆盖、工作单位。伊朗Ilam Eyaleti Dehluran Bolgesi Abu Ghoveyr Ovasi'nda colleesme degerlendiililmesi Modeli kullanilak，伊朗Ilam Eyaleti Abu-Ghoveyr Ovasi'nda colleesme zararinin degerlendiilmesi ve belirlenmesi amaclanmistir。但阿玛克拉，曾经的细胞系统，jeoloji ve arazi kullanim haritalarini，甚至calisma birim haritalari oluturulmustur。但是，在阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗，阿富汗。Elde ilen sonic, alanine %31.67 sinin collesme orta (II) sinit % 68.33 unise siddetli (III) sinit % oldugunu gostermistir。anhtar Kelimeler: sininiflandirma, Model, Olcut, Bitki Ortusu, Calisma Birimleri收稿(Gelis): 15.04.2016 -修订(Duzeltme): 20.05.2016 -接受(Kabul): 13.06.2016引用(Atif): Heidarizadi, Z.， Karimi, H.， Arami, S.A, 2017。伊拉姆省德洛兰阿布-高维尔平原沙漠化危害评价伊斯坦布尔大学林业学院学报，67(1):49-64。DOI: 10.17099 / jffiu.35680
