Differences is the fact that forest fires are dominated by all-natural aspects and have a high correlation with meteorological information, whereas crops residue burning is impacted by human activities in addition to meteorological circumstances. three.two. Considering Anthropogenic Management and Manage Policy to Forecast Fire Points (Situation 2) 3.2.1. Employing All-natural Things to Forecast Fire Points soon after the Implementation of Management and Handle Policies Jilin Province has prohibited the open burning of straw in specific regions since 2018. To explore regardless of whether only organic things can be utilised to forecast crop residue fire points after these management and handle policies were established, we continued to utilize the model created in Section 3.1.2 to forecast fires in Northeastern China from 2018 to 2020. The number of fire points was 178 for the duration of this period, and an further 178 no-fire points had been randomly chosen because the forecasting dataset. The results from these tests are shown in Table 4.Remote Sens. 2021, 13,9 ofThe forecasting accuracy of outcomes was 52.48 , which can be reduce than the result for 2013017 (77.01 ). As shown in Table four, the amount of fire points forecast by the BPNN was much less than the observed value. The proportion of case TN was larger than the proportion of case TP when the forecasting was right. The significant reduction in accuracy immediately after anthropogenic management and handle policies had been implemented suggests that only like organic variables inside the model was insufficient to forecast crop residue fires. Additionally, the proportion of instruction to forecasting samples approached 99:1, which potentially adds towards the inaccuracy in the neural network, as the proportion can have an effect on the output results.Table 4.

Adding Anthropogenic Management and Control Policies to Develop the BPNN Model To account for the influence from the burning ban policy and to reduce inaccuracies within the model output, we carried out a forecasting scenario utilizing the crop residue fire points from 2018020. In this situation, eight all-natural factors (five meteorological variables, two soil GYKI 52466 Neuronal Signaling moisture content material variables and the harvest date) and anthropogenic management and manage policy data (the straw open burning prohibition areas of Jilin Province) have been incorporated as input variables. Fire point information from 2018019 in Northeastern China have been chosen to create the model, and information from 2020 have been utilized for forecasting. The sample sizes utilised within the education and forecasting datasets have been 248 and 125, respectively. Just after 20 trainings, the accuracy with the very best model reached 91.08 , which was far greater than prior versions. These findings show that the integration of anthropogenic management and control policy variables enabled the production of an precise model to forecast crop residue burning in Northeastern China. The forecasting benefits are shown in Table 5, with an all round forecasting accuracy of 60 . Compared together with the results presented in Section 3.two.1, the accuracy was drastically larger right after adjusting the amount of samples. Though the forecasting accuracy right after adding the straw burning p.
