本文从纬度位置、海陆位置、垂直地带性、剥蚀夷平面和岩溶负地貌等方面,分析了鄂西山地泥炭的成矿因素。由于区域等级不同,控制泥炭形成的主导因素也有差异:区域越大,地带性因素的影响越明显;反之,区域越小,非地带性因素——主要是中、小型负地貌——的影响越明显。从全球来说,副热带的泥炭是相对贫乏的,但是处于副热带的鄂西山地,由于非地带性因素的影响,在某些地方泥炭并不少。根据这个指导思想,笔者对中国副热带泥炭资源的区域性分布规律进行了初步预测。
In this paper, we analyzed the petrogenesis factors in mountainous areas of western Hubei from aspects of latitude, land-sea position, vertical zonality, denudation and negative karst topography. Due to the different regional levels, the dominant factors controlling peat formation are also different. The larger the area, the more obvious the influence of zonal factors. On the contrary, the smaller the area, the more the influence of non-zonal factors - mainly medium and small negative landscapes obvious. Globally, subtropical peat is relatively poor, but in the subtropical western Hubei Province, peat is not uncommon in some places due to non-zonal factors. According to this guiding principle, the author made a preliminary forecast on the regional distribution of subtropical peat resources in China.
