AbstractWith a great deal of field investigation as its groundwork, this study applies soil geographic generation theory, diagnosis theory and ecology in describing the soil-forming factors, soil-forming characteristic and distribution laws of soil formation in the planting areas in the Chuanjiang Basin (referring to the valleys of the Minjiang, Tuojiang, Fujiang and Jialing rivers), and the relations between them. Then, the study conducts a standardized and quantized classification of soil system, and discovers in forest belts the physical and chemical properties, fertile features and productiviity of forest soil, accentuating the issue of soil moisture which bears close relation to silivcultural techniques and benefits as well. Supported by adequate data, the study further explains from many aspects the relations among soil moisture, physical and chemical properties of soil, litter in forests, and the content and distribution depth of of organic matter in soil. It also stresses the enhance protection and management of forest. It goes on to direct its attention to the evaluation of entities, items, standards and treatment means regarding the soil quality in the planting areas of the Chuangjiang Basin, by way of system theory and fuzzy mathematics method. This is followed by a quality assessment of soil types and areas for forestation with soil subgroups as cells. According to the attributes of the forests and soil for plantation in the areas, this study defines the evaluation entity as soil itelf, and chooses as evaluation factors 10 items such as soil quality, pH, etc. In an attempt to set up expert system for the evalution of forest soil quality,the study invited a number of specialists concerned to grade evalution factor quotas. Finally it applies a fuzzy, comprehensive approach to the all-around appraisal of the type and divisions of soil for plantation.
Other Abstract本文在大量野外考察的基础上,首先运用土壤地理发生学、诊断发生学原理和生态学观点阐明了川江流域营林区的成土因素、土壤形成特点、分布规律,以及三者间的关系;进行了标准化、量值化的土壤系统分类;分林带揭示了林下土壤的理化性质,肥力特征和生产问题,特别突出了与营林技术和效益十分相关的土壤水分问题,并用大量数据从多方面说明了土壤水分,土壤物理性能,及其森林枯枝落叶、土壤有机质含量和分布深度等影响因素之间的关系,同时指明营林造林必须加强护育管理的重要意义。接着采用系统论和模糊数学方法对川江流域营林区土壤质量评价实体、评价项目、评价标准、处理手段等诸方面进行了探讨,以土壤亚类为单元对宜林土壤类型和区域进行了质量评价;根据区内森林和宜林土壤的特点,将评价实体定为土壤本身,并选择土壤质地、pH等土壤属性为主的10个项目为评价因素,邀请众多专家对评价因素指标进行分级和权重分配,建立森林土壤质量评价的专家系统}采用模糊综合评判法进行宜林土壤类型和分区的综合评价。
