Soil water condition is calculated by watsat model , its result ( suff ) is input into ales . the soil water condition is sufficient for maize in most of handan , suff value is between 0 . 8 and 1 . 0 根据邯郸地区1 25万soter土壤土地数据库和ales土地适宜性评价模型原理，建立了基于水分满足程度、土壤侵蚀风险、土壤肥力指标的邯郸地区夏玉米适宜性决策树模型。

Trough overlaying of landform , parent material and soil maps , soter unit database is developed . moreover , soter land resource database was established based on soter unit map and climate region map . soter land use database was built based on china land use classification and soter socio - economical database is built base on statistical data 在此基础之上，更新土壤属性生成母质图，进而利用土壤普查资料中的剖面记载与剖面描述将邯郸地区土壤发生分类转换为系统分类，邯郸地区存在雏形土、新成土、有机土、人为土、盐成土五个土纲十三个土类二十一个亚类。

The land evaluation result ofhandan district show : 19 . 7 % land is unsuitable for agricultural use for soil erosion risk ; 2 . 5 % land is unsuitable for agricultural use for poor soil water condition ; 9 . 5 % land is marginally suitable because water or nutrition condition is not good enough ; 68 . 3 % land is suitable or very suitable for agricultural land use . the third part is the application of soter land information system in land use analysis based on statistical method and clue - s model . through land use analysis in handan , the main type of land use in handan is agricultural land use 土地利用整体结构在1980 - 2000年没有发生太大变化，只是林地上升至第2位形成耕地、林地、草地-城乡工矿居民用地、水域、未利用土地的结构；邯郸地区土地利用结构空间分布研究表明：西部山区土地利用结构为林地、草地、耕地、水域、建设用地和未利用土地；中部丘陵台地区土地利用结构为耕地、草地、建设用地、水域、林地和未利用土地；东部冲积平原区土地利用结构为耕地、建设用地、林地、水域和草地。

This dissertation is mainly about regional land resource evaluation and land use analysis based on g1s and soter ( soil and terrain spatial and attribute database ) database . the research content is composed of three parts . the first is medium scale soter database study , in this part , the new landform indexes are studied , which are elevation classification , slope classification and relief index classification 在邯郸地区1 25万soter土壤土地数据库建立方面，主要探讨了适用于该比例尺的主地形体指标，提出海拔高度分组指标、坡度分组指标和地势起伏强度分组指标，并利用上述三个指标组合划分出邯郸地区中坡度丘陵( sh ) 、低坡度山前台地( lm ) 、山谷( lv ) 、中坡度山体( sm ) 、山前倾斜平原( lf )和冲洪积平原( lp ) 6个主地形体组分。

All of theses database was integrated into a land information system , which can be used to land evaluation and land use analysis . the second part is the application of soter land information system in land evaluation , based on water balance model watsat , crop simulation model ps 123 and ales ( automated land evaluation system ) . the handan land evaluation model was built in ales based on expert knowledge and farmer s " experiences , it includs three decision trees , namely soil erosion risk , soil water condition and soil fertility 以邯郸地区1 25万soter土壤土地数据库为基础，探讨了土壤参数区域化问题，并利用watsat区域水分平衡模型，研究了邯郸地区区域水分平衡：大部分地区土壤水分满足夏玉米生长需求， ( suff )值为0 . 8 - 1 . 0 ，非常适宜；部分地区如大名地区、邯郸和永年部分地区、涉县沟谷坡梁地区土壤水分适宜夏玉米生长， suff值0 . 4 ? 0 . 8 ；不适宜地区， suff值0 . 2 ? 0 . 4 ，主要集中于丘陵山区以及平原古河谷地砾石和粗砂分布区。

Pedodiversity is a new theory and method based on biodiversity conception in ecology but applied to non - renewable non - biological resource that was developed since the 1990s . this paper applied pedodiversity analytical theory and method to analyze the spatial variability of the soils developed on different parent materials and terrains , the data source is 1 : 1 , 000 , 000 scale soil and terrain digital database ( soter ) of shandong province , china 土壤多样性理论是20世纪90年代发展起来的、基于生态学中生物多样性概念但应用于不可再生性非生物资源的一种新的理论与方法.本论文应用土壤多样性分析理论与方法，以山东省1 ： 100万土壤-地形体数字化数据库（ soter ）为数据源，对不同母岩、不同地形上发育的土壤空间可变性进行了研究。
