摘要
喀斯特环境是一种脆弱性很强的生态环境,在我国有较广的分布,在滇、黔、桂三省区分布特别集中,是制约我国西南经济发展的主要因子之一。以往虽然已开展了一些有关喀斯特环境方面的研究工作,但在土壤退化方面的研究还是一个空白。本文论述了喀斯特环境中土壤退化的研究现状、土壤退化的严重性及其特点、土壤退化的研究方法,提出了喀斯特环境土壤退化的时空动态模拟研究方法和关键性的问题。
Karst, which widely distributes in China, espaically in Yunnan, Guizhou, Guangxi province, is one of the weakest kind of ecological enviroments, which is one of the main factors that restrict economic development in south west China. Although many researches on karst environment have been done, there is little study on the soil degradation. Therefore, the paper first discusses its research situation, its seriousness and characteristics, and its research methods, and then puts forward the study way of space time simulating soil degradation and the key problems in karst environment.
