浑善达克沙地荒漠化指标评价的研究

Study on Desertification Assessment Indicator System in Hunshandake Sandy Land

土地荒漠化评价是荒漠化研究中的重要问题。本文以浑善达克沙地为研究对象,采用实地调查和室内分析的研究方法,提出了该地区土地荒漠化评价体系确定的原则,并通过分析和筛选,选择出能够显著评价该地区土地荒漠化状况的3个指标,从而建立了浑善达克沙地土地荒漠化的评价指标体系。针对该地区土地景观生态系统的复杂性和模糊性,运用模糊综合评判的方法对所获得的数据进行了定量分析,从而验证了该评价指标体系与实际调查情况基本相符。

The land desertification assessment is an important theory in the research of desertification. The investigation object is Hunshandake Sandy Land. By investigating on the spot and analysis in the laboratory, the assessment principle is proposed in the area. Three assessment indexes are chosen and the assessment index system of land desertification in Hunshandake Sandy Land is set up. The information is dealt with quantitative analysis by fuzzy assessment in accordance with complexity and fuzziness of land ecological system. The assessment indicator system fits with investigation on the spot.
