通过嘉善全县域4点/km^2密度的表层土壤调查采样调查,取得土壤地球化学元素含量背景值,并依据相关标准进行土壤养分质量和环境质量评价。统计分析表明:全县表层土壤地球化学元素含量空间变异小;土壤养分元素中,有机质、氮、钾总体丰富,磷在该县东南部丰富、西北部缺乏,钼在较多地区缺乏,铁、锰、铜、锌均属丰富,硼为中等含量,有效性钙、有效镁含量丰富,有效态硫、有效硅绝大部分为丰富区;表层土壤的环境质量总体为轻度污染,中度污染区零星分布。

Background values of topsoil in Jiashan obtained by the mathematical statistics for the topsoil sampling survey results in the hole country (densty is 4 points/km2), mndicate the county have small spatial coefficient of variation for the element abundance of topsoil. And incorporation with the soil nutrients and environmental quality are evaluated by the standards of "The quality of cultivated land survey in Zhejiang province", we found that the soil is in rich in organic matter, N and K ;in the east and sOuth of the county is in rich in P, but lack in the northwest; the area of lacking Mo is larger; Fe, Mn, Cu, Zn, Ca, Mg and the most of S, Si are in rich level; B is in moderate level. Therefore ,overall of the environmental quality of entire countv topsoil are sli(]ht DoIlution. and the moderate pollution area scattered distribution.
