摘  要：
【目的】研究适用于塔里木河流域胡杨林春尺蠖危害中等尺度遥感监测方法。【方法】基于国产卫星HJ星CCD数据时间序列,构建监测模型,以塔里木胡杨国家级自然保护区为例,进行遥感病虫害监测研究。【结果】2017年3月下旬至4月上旬,胡杨林NDVI均值呈上升趋势,4月下旬至5月上旬呈明显下降,5月中旬后时,其NDVI再次上升;4月中旬至5月上旬,春尺蠖幼虫以3龄、4龄、5龄为主时,胡杨林被危害较为严重,其监测精度高达85%,但是,3月下旬至4月上旬,当春尺蠖幼虫以1龄、2龄为主时,胡杨被危害程度较轻,其监测精度较低为5%;研究区西侧轮台县胡杨林较先受到危害,东侧尉犁县胡杨后受到危害。【结论】我国HJ卫星,通过植被指数可有效评估塔里木河中游胡杨林受春尺蠖危害情况,当且仅当植被受害较为严重时其精度较高。4月中旬至5月上旬,春尺蠖幼虫以3龄、4龄、5龄为主时,是春尺蠖严重危害胡杨林的主要时期。由于研究区西侧轮台县春尺蠖发生较早,胡杨林较先受到危害,东侧尉犁县春尺蠖发生相对较晚,胡杨林后受到春尺蠖危害。

摘  要：
【Objective】The study aims to explore a large area monitoring method for the damage of Apocheima cinerarius larvae on Tugai forest in middle reaches area of the Tarim River. 【Method】This paper made use of satellite HJ A/Bsatellite CCD data to construct monitoring model in Tarim National Nature Reserve based on time series for monitoring the damage of Apocheima cinerarius on Tugai forest. 【Result 】In April2017,NDVI average value of Tugai forest increased first,decreased in late April,and shortly afterwards the NDVI began to rise again; From middle of April to early May,when the larva of spring geometrid was mainly at the 3 rd instar,4 th instar and 5 th instar,the forest of Apocheima cinerarius was seriously damaged,and its monitoring accuracy was as high as 85%. However,from late March to early April,when the first instar and2 nd instar were the dominant larvae,Populus euphratica was less harmful and its monitoring accuracy was lower than 5. The result showed that the forest of Populus euphratica in Luntai County,west of the study area,was damaged first,then the east part of Yuli County was damaged afterwards.【Conclusion】China's HJ satellite can effectively monitor the damage of Apocheima cinerarius on Tugai forest in middle reaches area of the Tarim River,but only when the Tugai forest damage is serious,the accuracy is high. From the time point of view,from mid-April to early May,the larvae of Apocheima cinerarius were 3,4 and 5 years old,this was the main period of the serious harm of the spring inchworm. From a spatial point of view,because of the earlier spring moth in the west of the study area,the Tugai forest was damaged first,and because the spring geometrid occurred relatively late in Yuli County on the east side,the Tugai forest was damaged later by the Apocheima cinerarius.
