航片在农业资源信息动态监测中的应用探讨

Exploration of applying aerial priut to dynamic monitor of agricultural resources information

将肮空象片应用于农业地面动态监测以监测农业资源信息的变化。我们在临安县进行了试验,用航片定点法代替常规定点法在地面布设永久监测点,此法准确且省工、省费用;对集中成片的林地等用航片的图面布点代替常规布点,此法准确、简便;用航片复位法代替常规复位法以在永久监测点进行动态监测,此法既可保证复位精度又简单易行;用肮片样方法代替常规法监测地类,此法既简便易行又大大提高监测精度。

Applying aerial print to agricultural ground dynamic monitor for observation the variation of agricultural resources information. We made some experiments in Linan County: The method of aerial prinnt fixed point replaced the conventional one to fix-permanent monitor point on the ground. The method is precise and can save time and money; We applied aerial print fixed point on print instead of the convention to the vast woodland etc., the method is accurate, simple and convenient; We substituted the method of aerial print returned location for the conventional one to monitor repeatedly of the permanent monitor point, the method is exact in returned location and easy to apply; the method of aerial print quadrat replaced the conventional one for land type of monitor, the method is simple and easy to do, and can raise greatly the precision of monitor.
