| 中文摘要 | 本文共分五部分，在论述该课题研究的必要性基础上，阐述了川滇干热河谷泥石流滩的自然条件，社会经济地位及其成因类型，接着系统论述了泥石流滩土地分类的依据、指标与系统，进而对蒋家沟泥石流滩进行了土地分类，随后研究了滩地土地类型特征，最后阐明研究意义和进一步研究的课题。笔者从泥石流灾害防治与滩地农业开发利用出发，以土地分类理论及泥石流滩的研究现状为基础，采用自然科学与社会科学相结合，宏观调查与微观采样分析相结合等观点进行室内外资料收集和整理，进而采用景观法、参数法及成因法划分土地类型。主要结论：①泥石流滩地是一种土地资源。②泥石流滩土地分类指标宜选用土壤质地类型、滩地成灾危险频率及水源状况，并进行三级分类。③泥石流滩地可划分为3类、9片、27段。④泥石流滩地依其质量的不同可划分为4个等级。⑤泥石流滩土地类型组合结构主要有4种类型，即条带状、弧状、阶梯状和镶嵌状。⑥泥石流滩土地分类有利于农业生产布局、环境优化、农田建设、滩地利用与管理及滩地危险度区划。 |
| 英文摘要 | This article contains five parts. First, on the basis of study the importance and necessity of classification, it is discussed that natural attribute, social economic attribute and contributing factor tynes of debris flow flat in Sichuan and Yunnan dry-hot valley. Second, it is expounded that the foundation, target and system about debris flow flat land classification. Third, it is studied that land classification of Jiang jia gully debris flow flat. Later, the nature of main land types of debris flow flat is expounded. In the end, the studying significance and further questions for study are expressed. Aim at preventing and curing debris flow, exploiting flat land for agriculture, the land classification are bosed on synthetical, leading factor and contributing factoar method. During the process, it is taken the way of combining natural sciences with social sciences, macroscopic exploring with microcsmic experiments to obtain data. Thus several ideas are suggested: ①debris flow flat is one kind of land resources ②It can be used as land classification turgets such as soil texture, dangerous level of the flat and water resource, in terms which three grades of land classification can be maken ③Debris flow flat can be divided into 3 types, 9 sub types, 27 small-subtypes; ④Land quality of debris flow flat can be subvided into 4 levels; ⑤There are 4 kinds of land structure in debris flow flat that is strip shape, ladder shape, arc shape and repeated combination shape; ⑥Land classification of debris flow flat has benefit to allocation of agriculture, the beauty of circumstance, capital construction on farmland, administration of land resources and distinguishing the different dangerous levels of the flat. |
