چکیده

در بیشتر خاک ­های مناطق گرم و مرطوب، افق کائولینیتی بیشتر افق گیبسیتی را می ­پوشاند، اما این مسئله نمی­ تواند ناشی از فرآیند یک شسته شدن ساده باشد. با اندازه­ گیری مقادیر عناصر شیمیایی برگشتی در لایه روی مواد آلی در اکوسیستم در چرخه جنگلی وارد گردیده است و این فرآیند مانع شسته شدن سیلیس به قسمت­ های زیرین شده و باعث پایداری بیشتر کائولن در قسمت­ های فوقانی گردیده است. ترکیب کانی­ های  این گونه خاک­ ها به وسیله فعالیت­ های بیولوژیکی نیز تحت تأثیر قرار می­ گیرد.

چکیده [English]

In most of warm and humid regions’ soils, the kaolinite horizon covers most of the gibbsite horizon, but this cannot be due to a simple process of washing. By measuring the amount of chemical elements returned to the layer on organic matters in the ecosystem in forest cycle, this process has prevented the silica from being washed down to the lower parts, causing more kaolin stability in the upper parts. The combination of minerals in these soils is also affected by biological activity.

23- Fifteen 80-cm conical litter traps were placed at random on the 140-m diagonal of a 1- ha piot Samples were taken from August 1980 to September 1982.
24- Analyses were obtained at the Centre de Pedologie Biologique, Nancy, France. Samples were calcinated at 500°C and dissolved by strontium metaborate melling. They were then analyzed by plasma emission spectrometry for Si, Al, Fe, Mn, Mg, Ca, Ti, and p and by atomic absorption spectrometry for Kand Na. Results were corrected from the loss of weight at 1000°C.
25- The phytomass of trunks, branches, and leaves was estimated by the method proposed by J.P.Lescure et al.[Acta Oecol. Oecol. Gen, 4,237 (1983)].
