摘  要：
以 1∶5万土壤类型图为数据基础 ,采用景观生态学结构定量分析方法 ,并以GIS技术为分析手段 ,对鲁西北地区土壤资源在空间上的分布格局进行了定量研究。其中 ,主要分析了面积特征、形态特征和类型特征等三大类的景观格局指数。研究结果表明 :(1)前述方法能够很好地揭示区域土壤资源的分布格局 ,其结果对农业生产布局、土地资源开发利用和整治具有一定的指导意义 ;(2 )研究区面积最大的土壤类型主要分布于缓平坡地上 ,是主要的农业利用土壤 ,但因所处的地貌类型和潜水条件 ,在利用过程中 ,应灌排配套 ,防止地下水位升高 ,导致次生盐渍化 ,而平均形状指数较大的土壤分布主要受微地貌的影响 ;(3)研究区土壤资源景观类型特征存在着明显的区域差异 ,而区域主导土壤类型的农业生产条件的好坏将直接影响该区域的土地生产能力

摘  要：
This paper takes 1: 50,000 soil type figure as dada base, adopts quantitative analysis for the structure of landscape ecology, using GIS technology as analysis method and conducts quantitative study on soil resources in north-west Shandong and their space distribution. The emphasis is laid onan alyzing the landscape distribution indexes of 3 kinds, like traits of area, form and type. Research results show that (1) The above mentioned methods could very well reveal distribution pattern of regional soil resources, thus exerting cert ain guiding significance to distribution of agriculture production and tothe de velopment and utilization of land resources; (2) At the experimental base,the l argest soil type is mainly located on gentle slopes. They are mainly soils for a griculture use. But owing to their geomorphologic type and phreatic water condit ion, irrigation and drainage should come in set in utilization, so asto avoid t he raising up of under-ground water and leading to salinized soil. While the dis tribution of soils with larger even form indexes is mainly influenced by micro-l andform; (3) There exist remarkable differences between traits of soil resources landscape types at the experimental base, and the quality of agriculture produc tion condition of the leading soil type in the region will directly influence th e land productivity of that region.
