摘要

以配准后的4期遥感影像数据为基础,采用遥感和地理信息系统技术并结合野外调查对现代黄河三角洲林地植被、草甸植被、湿地面积进行了动态监测.结果表明,在1977~2004年间,植被覆盖面积逐年增加,年均增加3373.68hm2;其中,柽柳、芦苇、碱蓬和农田植被面积分别增加了1066.14,314.19,1128.87,5811.71hm2;刺槐林面积呈波动变化.初期湿地有河流、沼泽和滩涂3种类型,后期又增加水库、水田、池塘等人工湿地类型.受黄河来水和人类活动的影响,河流、沼泽湿地面积呈减少趋势,而水库、水田、虾池、滩涂湿地面积明显增加.

Based on 4 period registration remote sensing data, combined with field investigation, the dynamic monitoring of forest vegetation, grass vegetation and wetland in modern Yellow River Delta was conduced by using the techniques of remote sensing and geographical information system. The vegetation cover area increased yearly between 1977 to 2004, with an average increase of 3373.68 hm2 per year, in wich the cover area of Tamarix chinesis, Phragmites communis, Suaeda salsa and cropland showed an increasing ten...
