After analyzing purple soil sampled from neijiang, leshan ofsichuan provinec and yuanmou of yunnan province, the contrast results of microbe quantity feature between surface and subsurface purple soil were obtained as follows. the content of soil organic matter, total and available nitrogen, phosphorous and potassium of surface was higher than subsurface, not relating to the type of purple soil and soil utilization way. the quantity of microbe _ bacteria, actinomyces and mould in surface purple soil was higher than subsurface, which indicated that the organic matter and airy condition in surface soil was more suitable for microbes growing. there was the same tendency in profile change of microbe quantity in purple soil located in temperate _ humid climate of sichuan basin in contrast with dry _ hot climate of yuanmou, yunnan. the nutrient situation of purple soil in sichuan basin shown that state of surface was better than subsurface, while in yuanmou of yunnan the state was on the contrary due to the degradation of surface soil
實驗室對四川內江、樂山和雲南元謀不同類型紫色土表層和亞表層微生物數量特性的比較分析表明：土壤有機質、氮磷鉀全量及其速效量均表現為表層高於亞表層，與紫色土類型和利用方式無關；三大類土壤微生物細菌、放線菌和黴菌數量均表現出表層高於亞表層，表明紫色土表層的有機質和通氣性優于亞表層，適宜於這三大類微生物生長；溫濕氣候條件下的四川盆地和乾熱氣候條件下的雲南元謀其紫色土微生物數量的剖面變化具有相同的趨勢，唯土壤營養狀況在四川盆地紫色土中表現為表層優于亞表層，而在雲南元謀紫色土中由於表層土壤的退化作用表現為亞表層優于表層的相反情況。Characteristics and calculation model of phreatic evaporation of sand - layered soil
