目前对农业土壤形成的动力,展开着极为尖锐的 争论,存在着两种不同的看法:一种看法是:自始至 终坚持人类生产活动在农业土壤形成中起主导作用。 人类的生产活动不但是内部因素,而是内部矛盾的主 要矛盾方面。人类生产活动不但可以通过农业土壤的 其他内部矛盾起间接作用,而且可以直接作用于土壤 起直接作用。总之,以人类生产活动为主导作用的五 大成土因素与人类生产活动的矛盾斗争是农业土壤形 成的动力推动农业土壤的形成发展变化。另一种看法 是:开始认为农业土壤形成的动力是人为控制下的大 小循环;继而认为是人为控制下的养分淋溶与累积, 最后认为土壤肥力因素的发展与肥力因素之相互制约 相互变化的矛盾。不管怎样,还是不承认人为因素是 内部因素,或只承认它是内部因素,但不能成为内部矛 盾,不能成为内部矛盾的一个方面。人类的生产活动
At present there is a very sharp debate over the dynamics of the formation of agricultural soils. There are two different views: one is that from beginning to end insisting that human activities play a leading role in the formation of agricultural soils. Human production is not only an internal factor but a major contradiction in internal conflicts. Human activities can not only act indirectly through other internal conflicts in agricultural soils, but also act directly on the soil. In short, the contradiction between the five major soil-forming factors dominated by human activities and human activities is the impetus for the formation of agricultural soil and the development of agricultural soils. Another view is: began to think that the driving force of agricultural soil formation under human-controlled cycle of size; then that under the control of man-made leaching and accumulation of nutrients, and finally that the development of soil fertility factors and fertility factors interact with each other changes contradiction. In any case, it still does not admit that human factors are internal factors or only admits that they are internal factors, but they can not become internal conflicts and can not become an aspect of internal conflicts. Human production activities
