Abstract

The present invention relates to the field of cultivated land identification, in particular to a method and device for identifying effective cultivated land. The method and device use long-time sequence Landsat TM remote sensing data as a data source, use slope SLOPE data as auxiliary data, and use normalized differential vegetation The index NDVI is used as a classification feature, based on the phenological differences of crops on agricultural land, and reflects the differences in planting period, spectral difference and other characteristics of crop species to the distribution of time-series NDVI data, and designs a normalized difference The object-oriented decision-making classification rules combined with vegetation index NDVI and other classification features can not only extract the spatial distribution information of some crops on agricultural land, especially in West Asia, but also understand their cultivation conditions without considering the complex vegetation of different crops. However, the data source required by this method is easier to obtain, the amount of data to be processed is small, the classification rules are simple, and the work efficiency is high. It is also applicable to areas where the distribution of cultivated land is relatively fragmented.

Description

technical field [0001] The present invention relates to the field of cultivated land identification, in particular to a method and device for identifying effective cultivated land, a storage medium and a processor. Background technique [0002] It is generally believed that the NDVI time-series data of crops have a good correlation with their morphological characteristics, biochemical parameters and phenological information. Using NDVI time-series data can obtain crop category information on arable land. Therefore, multi-temporal time-series remote sensing image data is used for target crop Information identification is one of the most commonly used methods at present. However, due to the uneven distribution of crop phenology information in each time period, it is customary to use the best time-phase combination of crops for crop identification, which mainly uses the intermediate difference between crop spectrum and phenological information. [0003] At present, there are n...
