摘要
峰林峰丛是形态最典型、特征最突出的喀斯特地貌,而喀斯特形态研究是喀斯特研究的基础。该文根据国内外相关文献资料,在全面梳理峰林峰丛地貌的概念内涵、形态特征、中西方不同表述的基础上,归纳总结了峰林峰丛地貌形态研究的发展历程。喀斯特峰林峰丛地貌形态研究经历了从定性描述到定量分析,从简单的数理统计、形态量计到分形分析,以及随多源、高分辨率数据的获取而发展起来的基于DEM和GIS空间分析技术进行精确定量分析等几个重要阶段。在分析总结上述峰林峰丛地貌形态研究过程及技术手段的基础上,指出现有的形态定量研究方法中存在的不足之处,对喀斯特峰林峰丛形态研究的前景做出展望,并提出峰林峰丛地貌形态研究的发展方向和亟待解决的关键问题。
Fenglin and Feiigct^ng landforms are the most typical Karst laiidforms because of their terrain morphology and geo-morphologic diaracteristics.T he research of Karst morphology is the basis of Karst landforms studies.Referring to the relevant lit eratures at home and abroad,this paper comprehensively discussed the concept,connotation,morphological features and differ-ent expressions of the Fenglin and Fengcong landforms.Also,the development of studies on the morphology of Fenglin and Fengcong landforms was summarized.It is known that the research on Fenglin and Fengct^ng landform morphology has devel-oped from qualitative description to quantitative analysis,from simple morphology and statistical analysis to fractal analysis.Be-sides,with the development of mult-source and high-resolution data,the analytical methods based on spatial analysis of GIS and DEM have developed for analyzing the morphological features of Fenglin and Fengcong landforms.In recent years,the high-res-olution Digital Elevation Model(DEM)data as well as DEM-based digital terrain analysis theories and methods have been for-mulated and perfected,which have created favorable ct^nditions forthe research of Fenglin and Fengcong landform morphological features.Based on the summarization of research processes and technical methods of studies on Fenglin and Fengcong landformmorphology,the shortcomings of the existing quantitative research methods have been pointed out,and prospects of the study on the morphology of Karst Fenglin and Fengcong have been made.In addition,this paper puts forward the development direction and critical problems that need to besolved in the future researdi on Fenglin and Fengcong landforms and the key problems to be studied urgently.
