摘要
在回顾国内外峰林喀斯特研究主要观点的基础上,进一步阐述了峰林喀斯特同时态系统演化的新观念。即峰林喀斯特系统内各类地形的形成与发展在时间上可以同步。这种“同时态多样化”是由于物质与能量输入和输出的方式、强度、数量与质量在空间上的差异和分布不均所引起的。同时在其发展过程中,系统间各部(子系统,还必然存在相互协同的内在联系。虽然由于内部条件和外部环境的具体差异,在系统形态(或子系统)组成上常常出现破缺。但同时态多样化,乃是自然界各种“演化着”的开放系统的普遍特征。
The article has reviewed the main viewpoints on the development & evolution of fenglin karst, discussed its system relations, gone further into reseachs for its evolutional theory, and drawn a few principal conclusions.
Karst landforms, such as fengcong (the Peak cluster-depression), fenglin (the Peak forest-plain), isolated peaks, and even residual hills, belong to the entirety of a fenglin karst system and are the organic composition of the system. The geomorphological constitution of the fenglin karst system always has been broken by the differences in the interior conditions and the outer environment. It is actually both a kind of mechanical division of the organic entirety of a fenglin karst system and a distortion of the whole development of the system in essence to dicide the geomorphic cycle stages and the evolutional sequence relations of those karst assemblage landforms only by the difference in outer relief forms-as to consider fengcong, fenglin and residual hills as young, mature and old landform respectively; to think that the evolutionary series of a fenglin karst system is from fengcong to fenglin, then to isolated peaks, and eventually to residual hills. In fact, the common character of the various open systems evoling in the natural world is the contemporary variety in thier outer forms.
From the system analysis of the whole development of fenglin karst, the author farther explained in the paper his views of the contemporaneous system evolution of fenglin karst and proposed that: 1.the changing landforms of fenglin karst system could be formed & developed contemporaneously (in the same geomorphic development stage); 2.this kind of 'The Contemporaneous Variety' is caused by'the spatial differences in ways, intensity, quantity and quality of the input & the output of material & energy; 3. meanwhile the different parts of the system (subsystems) must have teamwork relations with one another in the course of its development.
The author at last pointed out that fenglin karst discussed in the paper should be distinguished from the tower karst & the cone karst adopted by the international literature as chere is a great difference in characteristics & genesis among them.
