摘要
在 1∶ 2 5万冬给措纳湖幅区域地质调查中 ,运用遥感信息的非可见光性、多时相性特征 ,研究黄河河源姐妹湖的泥沙特征及其演化规律 ;河源沙漠化的形成和结构特征等生态环境问题。对东昆仑活动断裂带的水系响应、环境效应进行遥感分析。建议在新一轮国土资源调查时 ,加大遥感技术在生态环境调查方面的应用力度 ,快速实现区调服务方向的转变。
During the regional geological survey in 1:250 000 Donggecuona lake,the author studied some ecologial questions such as the feature and evolution of silt in Sister lake at Huanghe riverhead,the formation and structure feature of desertization based on the invisible light nature and poly-time phase of remote sensing information,and then discussed the water system and environment effect respondent to the activety of eastern Kunlun fault zone throuth remote sensing analysis.Finally,the author suggested that we should increase remote sensing technology in the investigation of ecological environment in the new round of land resources survey in order to speed the change of service direction of regional geological survey.
