摘要：利用遥感手段对农田防护林的经营阶段进行识别,为农田防护林经营管理提供快速、及时的信息。利用多时相遥感影像,结合农田防护林经营理论,制定了农田防护林经营阶段的遥感监测方法,并在长春市德惠县选择10km×10km样区,利用TM/ETM遥感影像,对不同监测周期的农田防护林经营阶段的监测结果进行对比。如果以逐年监测结果作为标准数据进行验证,3a周期监测结果的总体精度为84.8%,6a周期监测结果的总体精度为78.4%。因此,综合考虑到计算效率、数据可获取性和监测精度,认为每3a为一个监测周期既符合农田防护林生长发育规律,又能获得较准确的监测结果。
The main purpose of this paper is to recognize the managing phase of shelterbelt by remote sensing,which can provide timely information for manager of shelterbelt.In this paper,by using multi-temporal remote sensing images,combined with the theory of management for shelterbelt,a method for monitoring the managing phase of the shelterbelt was established.Taking an area of 10 km×10 km in northern Changchun as examples,we used the TM and ETM images to analyze the managing phase of the shelterbelt in the area,and compared the relative precision resulted from different monitoring period.The results showed that,compared with the results of the annual monitor,the whole precision of three years period was 84.8%,and that in the period of six years was 78.4%.Therefore,based on an overall consideration of computation efficiency,data availability and monitor precision,it is concluded that monitoring result of three years period can not only coincide with the growth and development law of shelterbelt,but also has an acceptable precision.
