Abstract

The invention provides a crop planting pattern classification method and system considering phenological characteristics, and relates to the field of vegetation remote sensing. By making full use of the difference of EVI time series curves in key phenological periods in the identification of planting pattern types, and by enhancing the weight of key phenological periods, the information of key phenological periods can be effectively used, and the information of non-critical phenological periods can be suppressed to improve the quality of crops. Accuracy of planting pattern classification.

Description

technical field [0001] The invention relates to the technical field of vegetation remote sensing, in particular to a crop planting pattern classification method and system considering phenological characteristics. Background technique [0002] Crop planting patterns are closely related to regional agricultural natural resources such as light, heat, water, and soil fertility. As the global climate changes, the distribution pattern of agricultural natural resources such as light, heat, and water is gradually changing, which will inevitably affect the temporal and spatial distribution of planting patterns. The planting mode is largely constrained by the local climatic conditions. The current conflict between man and land has led to an increase in the intensity of cultivated land use. On the one hand, it is necessary to increase food production, and on the other hand, it is also necessary to ensure the sustainable development of agriculture. Therefore, timely and accurate monit...
