摘要
利用遥感技术对汶川县地震前后的遥感数据进行处理,并借助GIS技术,统计分析了汶川县农田土壤损毁状况。研究表明,汶川县农田土壤损毁程度严重,损毁主要土壤类型为:褐土、棕壤和黄棕壤,主要损毁农田类型为山地旱地。在此基础上提出了农田土壤保护建议,对地震造成生态环境的影响提供了重要的参考和借鉴。
The remote sensing technology was used to survey the damage of farmland before and after the Wenchuan County earthquake.Results had shown that the extent of the soils damage were:cinnamon,brown soil and yellow-brown soil,the main type of damage was farmland dryland mountain.On this basis the protection of agricultural soils had been suggested.
