“覆土绿植”对秦岭宝鸡段违建整治区土壤养分的影响

Influence of Plants on Soil Nutrient at the Region of the Demolition of Unauthorized Construction in Baoji Area of Qinling Mountains

秦岭违章建设别墅区的整治和后续覆土绿植措施的实施,表明秦岭宝鸡段生态环境恢复工作已全面开展。本研究通过野外采样和室内分析相结合的手段,分析“覆土绿植”措施对秦岭宝鸡段各违建整治区土壤养分及容重的影响,结果表明,虽然在“覆土绿植”措施下,违建整治区土壤养分(有机质,全氮,速效磷和速效钾)低于其对照组,但是两者之间差异不显著,表明“覆土绿植”措施在恢复违建整治区土壤养分状况方面起到了积极的作用。因此后期对违建整治区在“覆土绿植”的基础上,开展其他有效措施,改善违建整治区土壤质量,提升该地区生态环境。

The implementation of covering plants on soil in the demolition of unauthorized construction in Baoji area of Qingling Mountains showed that the restoration of ecological environment has been carried out.By the methods of field sampling and indoor analysis,this article illustrates the influence of plants on the soil nutrient at that region.The results showed that the soil nutrient such as soil organic matter,total nitrogen,available phosphorus and available potassiumin in the area of unauthorized construction is low than the control group(after the demolition of unauthorized construction),however,the difference is not significant(at P>0.05 level),which show that plants have positive roles in enhancing the soil nutrient levels.Furthermore,others measures should be taken to enhancing soil quality and improve ecological environment.
