Abstract

The invention relates to a regional future vegetation index estimation method applied to a climatic change scene, which comprises the following steps: firstly, preliminarily selecting characteristic variables, then generating a sample, and setting key parameters of a model; calling a random forest model in a Sklearn machine learning library through Python, and inputting sample data S for model training; secondly, performing random forest model prediction performance evaluation; sDSM forecasting factor screening is carried out; calibrating and verifying the SDSM model; constructing a forecasting factor set of the random forest model; and finally, inputting the generated forecasting factor set into a trained random forest model to carry out future vegetation index estimation under the influence of climate change. According to the method, the future vegetation index of the region can be estimated according to different weather change scenes in the future.

Description

technical field [0001] The invention relates to the field of ecological environment quality assessment, in particular to a method for estimating regional future vegetation indices under climate change scenarios. Background technique [0002] The current global climate is undergoing significant changes characterized by warming. The IPCC Fifth Assessment Report pointed out that the average global surface temperature increased by 0.85°C from 1880 to 2012. Relevant studies have pointed out that meteorological variables such as temperature and precipitation are important environmental factors affecting the growth and development of vegetation, and the vegetation index reflects the state of vegetation growth and is an important indicator of the quality of the regional ecological environment. [0003] At present, the research on climate change and vegetation index is more focused on the response relationship between the two, and the research focuses on historical data, while the re...
