试题分析:

【1】一个因素的变化导致其他因素甚至整个环境的变化,属于自然地理环境整体性的表现。黄土高原由于植被破坏,导致水土流失,体现了地理环境的整体性。

【2】生物是土壤发生发展中最活跃的成土因素,由于它的创新作用,才使得拇指产生肥力而转变为土壤.再一定意义上讲,土壤的形成过程就是在一定条件下,生物不断改造母质而产生肥力的过程,没有生物的参与和作用,就没有成图过程.正是由于生物群体的作用,才能把太阳辐射能引进成土过程,才能把分散于岩石圈、水圈和大气圈的营养元素向岩石风化壳(母质)的表层聚积,形成以肥力为本质特征的土壤,并推动土壤的发展演化.

【3】本题考查土壤的形成条件。陡峭的山坡受重力影响,水流速度比较快,侵蚀作用强,地表疏松物质的迁移速度快。所以本题选择A选项。地表疏松物质的侵蚀速率较慢B错误;光热条件没有关系,C错误;水分条件太差不是主要因素,D错误。
