摘要
采用航卫片对罗田县和两个小流域土壤侵蚀程度(侵蚀级及其面积)作了调查,查明了侵蚀严重的地区主要分布在300米以下的丘陵地段。在分析侵蚀土壤理化性质的基础上,提出防治土壤侵蚀的措施。
Soil erosion in Luotian County and two associated tributaries was surveyed in large scale. It was found that the erosion was most serious at the rolling hills with altitude below 300m, and that increasing vegetation covering is the most efficient measure to improve soil chemical and physical properties. Herbage crops are recommended for soil erosion control and agricultural development in this area.
