摘要
对新疆棉花遥感监测识别区域进行划分,其目的是为新疆棉花监测运行系统中的样点布设、遥感信息获取和处理、遥感最佳时相的选择、作物识别和面积估测等提供科学依据。以遥感监测区划的原则、依据和指标为指导,以新疆遥感图像数据库、地理基础与专题图空间数据库、统计数据库为研究资料,结合农作物物候历、地面光谱与实地调查进行分析研究,做出了新疆三大棉区的遥感信息源区的划分、最佳时相区的划分与棉花遥感识别区的划分。区划结果表明:新疆三大棉区均定为陆地资源卫星信息源区;新疆三大棉区除吐鲁番地区6月上、中旬为棉花识别的次佳时相期,8月下旬为最佳时相期外,其他棉区棉花遥感识别最佳时相均为9月,次佳时相也均为6月;并在此基础上,把新疆三大棉区划分为6种棉花遥感识别区,即主棉区、重棉区、次重棉区、次棉区、零星棉区与无棉区。
This article intends to offer scientific basis for samplings arrangement, information sources selection, optimum remote sensing temporal selection, crop discrimination and cotton area estimation. Based on the regionalization principle, basis and index of the cotton monitoring using remote sensing, according to the database of remote sensing images of Xinjiang, the geography foundation and the special subject images database, the Stat. databases, combining the spectrum measurements of crops and crop phenological calendar, the analytical research was carried out. The results indicate that： the three main cotton regions in Xinjiang region could use land resources satellite as information sources; in all the cotton regions, with the scheme for the regionalization of the cotton remote sensing information sources, the optimum remote sensing temporal for the three cotton regions is September, the second temporal is June, but in TULUPAN, it is late August and the early and middle June; based on the results, the three cotton regions in Xinjiang region could be divided into six subareas, which are main cotton regions, heavy proportion cotton region, inferior heavy cotton region, inferior cotton region, sparse cotton region and no cotton region.
