“3S”技术在水稻种植面积动态变化监测中的应用

Application of“3S”Technology on Monitoring the Dynamic Change of Rice Area

以黑龙江省三江平原水稻主产区为样区,利用遥感(RS)、地理信息系统(GIS)和全球定位系统(GPS)技术对水稻种植面积进行监测和评价,及时掌握水稻种植面积和变化趋势,能够在短时间内完成监测,为水稻生产的发展提供科学依据。与常规方法比较,具有精度高,时间短,人、财、物力消耗少,可广泛应用。

Took Sanjiang Plain in Heilongjiang province as sample, where was rice main planting region, the rice area was monitored and appraised by the＂3S＂ technology, The technology could finish monitoring in short time and grasp the planting area and the variable tend in time and provide the scientific basis for rice cultivation. Compared with the traditional method, it owned the merits of high precision, short time, and coast-saving, so it could be applied widely.
