摘　　要：根据广州大学城的实际情况,对草地、林草地两种土地利用类型进行野外光谱监测,并与中巴地球资源卫星02B(CBERS-02B)的影像进行比对研究。其中,每个实验区域为2×2个像素大小,约1600m2,共布9×10个点,以监测点位上植物的反射光谱。为提高监测点位的定位精度,在实验中,引入基准站+流动站(1+1)组成的实时动态差分系统,来确定实验区域的范围和监测点的位置,取得较好的效果。According to actual situation of Guangzhou University town, the authors monitor the vegetation spectrum of grassland and forest -grassland and contrast with the remote sensing image of CBERS-02B satellite. In monitoring, every experiment area includes 2 × 2 pixels, it＇s 1 600 square meters in total, and set 9 × 10 points to monitor vegetation spectrum. In order to improve positioning precision of monitor points, the authors introduce RTK system （ include base station and rover station ） to determine the range of experiment area and position of monitor points. In practical application, this method achieves some effect and has some practical value.
