چکیده

هدف از این تحقیق، بررسی میزان کارایی روش LFA جهت پیش‌بینی میزان شاخص‎های تنوع گونه‌ای می‌باشد. نمونه‌برداری بر روی 140 لکه گیاهی و با استفاده از 140 پلات یک مترمربعی در طول 14 ترانسکت و به صورت تصادفی- سیستماتیک صورت گرفت. بر طبق دستورالعمل روش LFA، شاخص‌های نهایی نفوذپذیری خاک، چرخه مواد غذایی و پایداری خاک محاسبه شد جهت تعیین تشابه بین شاخص‌های تنوع، پارامتر‌های سطحی خاک و شاخص‌های نهایی از آنالیز خوشه‌بندی، در محیط نرم‌افزار PAST استفاده گردید. نتایج نشان داد که در سطح یک درصد (01/0 P≤) شاخص تنوع شانون توسط پارامتر ارتفاع از سطح دریا، شاخص سیمپسون توسط پارامتر چرخه موادغذایی و شاخص غنا توسط هر دو پارامتر ارتفاع از سطح دریا و چرخه مواد غذایی قابل پیش‌بینی می‌باشد. به نظر می‌رسد روش LFA با مورد نظر قرار دادن برخی از پارامترهای سطحی خاک و امتیازدهی به آن‌ها می‌تواند شاخص‌های نهایی ایجاد نماید که این شاخص‌ها می‌توانند عملکرد اکوسیستم را نمایش دهند.

چکیده [English]

This study aimed to evaluate the efficiency of the LFA method to predict the species diversity indices. Sampling was carried out using 140 plots of 1 m2 along 14 transects based on a randomly-systematic design and so, the final index of soil infiltration, nutrient cycle and soil stability was calculated. Also, the cluster analysis was applied to determine the similarity between the variability indices, soil surface parameters and final indices by using PAST software. The results showed that at the level of 1percentage (P≤0.01), the Shannon diversity and Simpson indices were predicted by altitude from the sea level and nutrient cycle parameters, respectively and, richness index were predicted by these two parameters. It seems that the LFA method can create the final indices by considering and scoring some of the surface parameters of the soil (eleventh indices) and these indices can finally display the ecosystem's performance finally display the ecosystem's performance.
