摘要
通过遥感技术对山东省东营市的土地资源类型的空间分异特征进行了划分,然后以土地资源类型图为基础,采用地理信息系统技术,结合东营市的实际情况,选择土壤、地形、潜水位与地下水矿化度等评价因子,结合工作区生态环境特点,抓住作用于区域生态环境的人文因素与自然因素,采用定量与定性相结合的方法,选择能够客观、准确反映东营市的自然评价因子,其在自然生态环境中的作用(建设性与破坏性),得出准确反映东营市土地资源适宜性特征的成果数据。
This paper mainly divided the space differential characteristics of land resources types in Dongying city, Shandong province using remote sensing technology. Then it takes map of land resources types as the base, using GIS technology, combining with the actual situation of the city, choosing evaluation factors of soil,topography,ground water table and degree of mineralization of ground water etc. , combining with the ecological environment characteristics in working area, seizing the human and natural factors that act on regional ecological environment, using the combination of quantitative and qualitative methods, choosing the natural evaluation factor that can reflect the characteristics of the city objectively and correctly and its（constructive and destructive） role in natural environment, and finally this paper gave the achievement data which can correctly reflect the characteristics of the land resources suitability in Dongying city.
