-
Using the semi-micro-kelvin, the sodium hydroxide-molybdenum stibium anti-color method, the CaCO3 molecular formula, soil drying method, ring sampler method to carry on correlation investigation and the analysis of soil different quality, the results showed that: (1) mountainous gray brow soils, the mountainous leaching gray brow, the sub-alpine brush meadow soil, the mountainous chestnut soil organic content respectively are 11.88%, 10.85%, 10.73%, 1.65%.(2)The soil volume-weight in 0-60 cm deep of Picea crassifolia, alpine bushwood, Sabian przewalskii, the low mountain bushwood, meadowland, open ground reduce in turn, but the gross porosity increases in turn.
