半干旱地区温室气体排放空间特征建模分析研究
|
摘要
采用空间插值法对半干旱地区空间进行分配,以空间分配结果为基础对温室气体排放数据进行采集与识别,对上述得到的温室气体排放数据进行预处理,主要是对干扰数据进行剔除,并对特征数据进行提取,将提取的温室气体排放特征数据采用多元回归方法进行分析,实现了半干旱地区温室气体排放空间特征分析模型的建立。通过实验得到,建立的半干旱地区温室气体排放空间特征分析模型的分析精准度比传统模型高出30%,说明建立的半干旱地区温室气体排放空间特征分析模型具备极高的有效性。
The spatial characteristics analysis model of greenhouse gas emissions in semi-arid areas is proposed. Spatial interpolation method is used to distribute the space in semi-arid areas. Based on the results of spatial distribution, the greenhouse gas emission data are collected and identified. The greenhouse gas emission data obtained above are pre-processed. The main purpose is to eliminate the interference data and extract the characteristic data to extract the extracted greenhouse gas. The data of greenhouse gas emission characteristics are analyzed by multiple regression method, and the establishment of spatial characteristics analysis model of greenhouse gas emission in semi-arid region is realized. The experimental results show that the analytical accuracy of the model is 30% higher than that of the traditional model, which indicates that the model is highly effective.
