Abstract

The invention discloses a crop planting structure monthly scale dynamic extraction method, which comprises the following steps of S1, determining an analysis region space range, performing data preparation, collecting a time sequence satellite remote sensing data set which is not greater than a monthly scale, performing unified processing in time to obtain monthly scale data, and simultaneously finishing pre-acquisition of sample data in a research region; S2, calculating texture features and normalized vegetation indexes by utilizing the preprocessed monthly-scale satellite remote sensing image data; S3, selecting high-information-richness texture features, and combining the high-information-richness texture features with the vegetation index to form a new image. The problems of long revisit period, difficulty in obtaining the optimal time phase, high price and difficulty in meeting the requirement of dynamic crop management of the conventional method are solved.

Description

Technical field [0001] The invention relates to the field of remote sensing planting structure monitoring, in particular to a method for dynamically extracting crop planting structures on a monthly scale. Background technique [0002] The planting structure of crops reflects the status of human agricultural production using agricultural production resources in a spatial range. It is important information for studying the types, quantity structure and spatial distribution characteristics of crops. It is also the basis for the adjustment and optimization of crop structure and the fine management of agricultural water use. The traditional methods of obtaining crop planting structure information mainly rely on local management departments to report level by level and regional sampling surveys. These two methods not only consume manpower and material resources, but also difficult to obtain spatial distribution information of various crops. [0003] With the development of remote sensing...
