Problems solved by technology

However, the time difference of farmland returning to farmland may be relatively large, and the classification method is mostly obtained by using one phase, so there may be some farmland information that cannot be effectively extracted or the tree planting in wasteland may not be recognized. Therefore, the existing traditional remote sensing There is some uncertainty in the accuracy of methods for extracting fallow and restored vegetation types

Abstract

The embodiment of the present invention provides a method and device for remote sensing identification of returned farmland information. By combining the first type of time-series remote sensing images with different spatial resolutions and the second type of time-series remote sensing images, the returned farmland in the target area can be identified. The determination of the area and the area of ​​the returned farmland area can make the determined area of ​​the returned farmland area and the area of ​​the returned farmland area more accurate, and provide support for accurate ecological restoration of dry areas.

Description

technical field [0001] The invention relates to the technical field of remote sensing, in particular to a method and device for remote sensing identification of returned farmland information. Background technique [0002] In view of the relatively fragile ecological environment in arid areas or the need to protect important ecological function areas, some farmland needs to be returned to forests and grasslands to maximize the value of the ecosystem. [0003] However, from a management point of view, it is necessary to make timely statistics on the specific time, location, area and restoration type of farmland conversion in different periods, as well as to give certain economic compensation to localities or farmers according to the time and area of ​​farmland conversion, and to monitor the conversion of farmland to forest. It also provides important support for the effect of grass ecological restoration. [0004] Due to its multi-time, multi-space and multi-spectral characte...
