| Abstract: |
| ［Purpose］Scientific understanding of multiple cropping and scientific improvement
of multiple cropping potential are of great practical significance for the implementation of the
food crop production strategy based on cropland management and technological application.
［Method］Based on the perspective of agricultural land system，this paper systematically
sorted out and summarized the research literature on multiple cropping practice，scientifically
developed the connotation of multiple cropping，and summarized and reviewed the research
progress on multiple cropping practice.［Result］The traditional definition of multiple cropping
is only for a single fixed year，and the multiple cropping system is a long-lasting，stable and
periodic intensive use of cropland，which can describe how different cropping practices and fallow
strategies are combined over many years，and is consistent with the characteristics of practical
cropping systems.Remote sensing mapping of multiple cropping system，scientific exploitation
of multiple cropping potential from the perspective of multiple cropping system and evaluation
of comprehensive benefit of potential improvement on macro scale will be the key content and
direction of multiple cropping research.［Conclusion］The study of multiple cropping system will
provide a new perspective for the evaluation of cropland intensification，which can serve for the
in-depth understanding of the current situation of multiple cropping and the scientific exploitation
of multiple cropping potential，and provide basis and support for the sustainable development of
agriculture. |
