摘要
在 1∶5万区域生态地质填图的基础上 ,通过土壤调查和剖面测制 ,查明了黄龙土地资源的水土流失现状、诱发因素 ,并针对其危害提出了治理措施 ,进而对土壤肥力状况作了一定的研究。重点讨论的黄龙土壤微量元素特征、环境背景值 ,对土壤环境进行了评价 ,对元素有效态对农作物的环境效益进行了初探。
The present sitution and cause for soil erosion in huanglong,Songpan have been found out on the basis of 1∶50,000 Regional ecogeological mapping,soil investigation and profiling,and appropriating control measures have been put forward.Soil fertility is discussed.Soil environment and environmental effects of active forms of elements on the crops are assessed based on minor elements in soil and environmental background values.
