Title:
RICE PRODUCTION POTENTIAL SIMULATION METHOD BASED ON LAND SYSTEM AND CLIMATE CHANGE COUPLING
Document Type and Number:
WIPO Patent Application WO/2023/245399
Kind Code:
A1
Abstract:
A rice production potential simulation method based on land system and climate change coupling, the method comprising the following steps: constructing a GM-FLUS model to simulate a change of a land system (S1); using a GAEZ model to estimate rice production potential (S2); and analyzing spatial distribution features and time change trends of the rice production potential in different scenarios (S3). By means of constructing a GM-FLUS model to simulate a change of a land system, in view of four future climate scenarios of SSP1-2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5 among shared socioeconomic pathways (SSPs) under a CAS-ESM2 climate scenario model intercomparison project, and by using a GAEZ model to take various factors such as climate, soil, terrain, a land system, etc., into consideration, rice production potential is estimated, thereby providing a technical support for coping with a future climate change, rationally using cultivated land resources and guaranteeing food security.
