摘要
[目的]揭示花山景区附近土壤环境质量演变状况及污染特点。[方法]以花山旅游景区附近的农业土壤为研究对象,对研究区内农田土壤环境质量和污染状况进行系统的调查研究。[结果]所有调查区域的农药含量均在最低检出限之外,符合国家的农药标准。依据土壤养分分级标准,所调查区域土壤的养分级别为极低。土壤比较贫瘠,氮、磷、钾含量都比较低。对保护区的蔬菜地、甘蔗地和水稻田土壤中氮、磷、钾的含量进行检测,其含量大小为:蔬菜地>水稻田>甘蔗地。[结论]花山景区附近应加强农药的科学施用,积极推广微生物肥料。
[Objective] The aim was to reveal the evolutions of soil envirounlent quality around Huashan scenic spots and its pollution characteristics. [ Method] With the agricultural soil around the Huashan scenic spots as subject, the agricultural soil environment quality and its pollution of the studied areas were investigated systematically. [ Result ] The pesticide contents in all the investigated areas were outside the lowest detection, which accorded with the national pesticide standard. According to the classification standard of soil nutrient, the grades of soil nutrient in all the investigating areas were extremely, low. The soil was relatively ＇barren and all the contents of nitrogen, phosphorus and potassium were relatively low. The contents of nitrogen, phosphorus and potassium in the soil of vegetable field, sugarcane field and rice field in the protective area were detected, their coutents were as follows： vegetable field 〉 rice field 〉 sugarcane field. [ Conclusion]The scientific fertilization of pesticide should be strengthened and microbial fertilizer should be actively popularized around Huashan scenic spots.
