中文摘要：

为摸清环渤海地区土壤养分含量空间分布特征及其主要影响因素,本研究以黄骅市作为研究区,采集该地区土壤表层（0～20cm）样品共310个,按照土壤农化常规分析方法进行室内分析测定,得到各养分含量状况;以ArcGIS为技术手段对土壤养分进行空间分析,得到碱解氮、速效磷、速效钾、有机质空间分布;对影响土壤养分含量的各因素进行空间分析,得到土壤类型、土壤质地、土壤pH的空间分布,最后将土壤养分与土壤类型、土壤质地、土壤pH进行相关性分析。结果表明,黄骅市土壤类型以盐化潮土为主,土壤质地以中壤为主,pH集中在8.0～8.5的碱性区间。碱解氮含量的主要影响因素是土壤类型,速效钾含量的主要影响因素是土壤类型和土壤质地,有机质含量的主要影响因素是pH,而速效磷的空间分布与土壤类型、土壤质地、土壤pH关系不大。

英文摘要：

In order to find out the spatial distribution characteristics and the main influence factors of the soil nutrient con- tent around Bohai sea area, Huanghua city was taken as a study area, 310 samples of soil surface layer （0-20 cm） were collected, the method of soil agroehemistry routine analysis was used, and the nutrient content status was got. ArcGIS tech- nology was used to analyze the soil nutrient spatially, and the spatial distribution of alkaline hydrolysis nitrogen, available phosphorus, available potassium, organic matter was got. Spatial analysis of the factors which effected the soil nutrient content was carried on, and the soil type, soil texture, soil pH spatial distribution was got. Finally, the relativity of the soil nutrient and soil type, soil texture, soil pH was tested. The results showed that, the main soil types in Huanghua city was salinized moisture soil, main soil texture was medium soil, pH concentrated in the alkaline range （8.0-8.5）. The main influence fac- tors of nitrogen content was the soil type, the main influence factors of available potassium content was soil type and soil texture, the main influence factors of organic matter content was pH, and the spatial distribution of available phosphorus had little relationship with soil type, soil texture and soil pH.
