摘要
基于遥感和GIS成像技术技术,选取不同年份青岛市沿海地区绿色植被遥感影像,综合该区地形图、各期沙化监测资料以及绿色植被种植情况,综合遥感监测数据和外部调查相结合的方法。对青岛市的青岛沿海绿色植被急速沙化的空间分布特征进行分析,在此基础上提出一种基于非稳态三维流动特征分析方法,实现了青岛沿海绿色植被急速沙化的空间分布特征分析。实验分析表明,青岛市沿海绿色植被沙化土地面积处于稳定,其扩展过程缓慢波动。其空间分布特征呈现缓慢波动-大幅波动-逆转的变化趋势。在沙化程度上表现为波动减弱趋势。
Imaging technology based on remote sensing and GIS technology, the selection of different years of Qingdao coastal area green vegetation remote sensing image, integrated the area topographic map,each phase of desertification monitoring data and green vegetation planting situation, comprehensive remote sensing monitoring data and the method of combining the external investigation. Of Qingdao Qingdao coastal green vegetation spatial distribution characteristic of rapid desertification were analyzed,and based on this, advances a kind of analysis method based on unsteady three- dimensional flow characteristics, implements the Qingdao coastal green vegetation spatial distribution characteristic of rapid desertification were analyzed. Experimental analysis indicates that the Qingdao coastal green vegetation in arid land area in a stable, its extension process is slow. Its spatial distribution characteristics of slow- volatility- reversal of fluctuations. In the trend of desertification degree performance for reduced volatility.
