20年来杭州市城区农业土壤性状比较研究
Comparative Study on Agricultural Soils in Hangzhou Urban Area in Last 20 Years
【摘要】 2006年对浙江省杭州市城区农业土壤进行了调查分析,并与第二次土壤普查进行了比较,结果表明:二十年来有些土壤种类由于城市化和农业种植结构调整而消失和改变;蔬菜基地的土壤肥力有显著提高,但与商住区和工业区之间养分不平衡;土壤重金属污染已得到控制,蔬菜基地和商住区生产的蔬菜可放心食用,但工业区的土壤已受到镉的污染。为此,提出了测土配方施肥和工业区治理镉污染的建议。
【Abstract】 The study was conducted during the soil survey of Hangzhou urban area in 2006,and its results were compared to those of the second general soil survey of China.The results showed:some soil species had been lost or changed due to the urbanism and adjustment of agricultural planting structure;the soil fertility had been enhanced in the vegetable bases while nutrient balance had been lost in the commercial and residential areas and industrial areas;the heavy mental pollution in the studied areas had been controlled,and the vegetables growing from vegetable areas and commercial and residential areas were safe.But the soils of industrial areas had been polluted by Cadmium.Therefore,we suggest soil test and formulate fertilization against Cadmium pollution in the industrial areas.
