• 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
  实验室对四川内江、乐山和云南元谋不同类型紫色土表层和亚表层微生物数量特性的比较分析表明：土壤有机质、氮磷钾全量及其速效量均表现为表层高于亚表层，与紫色土类型和利用方式无关；三大类土壤微生物细菌、放线菌和霉菌数量均表现出表层高于亚表层，表明紫色土表层的有机质和通气性优于亚表层，适宜于这三大类微生物生长；温湿气候条件下的四川盆地和干热气候条件下的云南元谋其紫色土微生物数量的剖面变化具有相同的趋势，唯土壤营养状况在四川盆地紫色土中表现为表层优于亚表层，而在云南元谋紫色土中由于表层土壤的退化作用表现为亚表层优于表层的相反情况。
• According to our analysis , the farmers in quzhou are in the second phase , which means they already have enough food and put much more inputs for earning high yield and high income . ( 4 ) the ground water table was getting down , caused by precipitation decreasing , no river water coming due to the upstream reservoir , complete drainage in rainy season and irrigation using groundwater
  ( 4 )自然降水量的降低、上游水库的拦蓄，使平原失去了获得水源的机会；内部防洪排沥体系的完善，致使入渗补充地下水减少；耕地灌溉率的增加，导致农业用水量不断加大，这些因素共同作用使区域水资源失去平衡，引起地下水位的下降，从而促使盐渍土表层脱盐。
