Abstract

The feature extraction accuracy and efficiency of traditional urban agglomeration construction land spatial expansion pattern evolution characteristics analysis methods still need to be further improved. Therefore, an analysis method of urban agglomeration construction land spatial expansion pattern evolution characteristics based on environmental characteristics is proposed. This method uses Gaussian weighting function to select remote sensing image feature points of urban agglomeration construction land and extract urban environmental features. According to the extraction results, the expansion parameters of urban agglomeration construction land are calculated, and the evolution characteristic analysis function is constructed. Experimental results show that the proposed method analyse the evolution of the characteristics, can be effectively extracting features of the evolution pattern of city group extension, and has a high efficiency, the maximum efficiency of the analysis and the extraction accuracy of 96% and 98%, respectively.

基于环境特征的城市群建设用地空间扩展格局演化特征分析

传统城市群建设用地空间扩展格局演化特征分析方法的特征提取精度和效率还有待进一步提高。为此，提出了一种基于环境特征的城市群建设用地空间扩展格局演化特征分析方法。该方法利用高斯加权函数选取城市群建设用地遥感影像特征点，提取城市环境特征。根据提取结果，计算了城市群建设用地的扩展参数，构建了演化特征分析函数。实验结果表明，该方法分析了城市群的演化特征，能够有效地提取城市群扩展的演化模式特征，并且具有较高的效率，分析效率最高，提取准确率分别为96%和98%。
