Treffer: 基于深度学习和物元的居民点适宜度与分布特征分析.

In response to a series of rural-related policies such as rural revitalization, by analyzing and understanding the spatial distribution characteristics of rural residential areas in Wenzhou City, we made a hierarchical evaluation of the suitability of rural residential areas, providing a reference for optimizing the layout of village-level residential areas. By combining the interfaces provided by the GSCLund, Python, Map World and Amap, we obtained road network data, water system data, DEM data, land-use data, and residential area data of Wenzhou City., we used Thiessen polygons and kernel density methods to analyze the spatial distribution characteristics and influence factors of rural residential areas in Wenzhou City, and used the object element model method to evaluate the suitability of rural residential areas in Wenzhou City. The residential areas in Wenzhou City are mainly distributed in the central coastal area with high density. From the perspective of natural factors, their distribution is mainly influenced by elevation. In terms of social factors, the dense distribution of residential areas is inversely proportional to the distance from rivers and roads. Overall, the suitability of residential areas in Wenzhou City is relatively high, with the best suitable residential areas accounting for 73.83% of total number of residential areas. Under the combined influence of natural and social factors, the village-level residential areas in Wenzhou City are highly influenced by natural factors, with terrain being the main factor. The overall suitability of these residential areas is relatively high, making them suitable for living. The result can provide some positive reference value for optimizing the layout of village-level residential areas in Wenzhou City. [ABSTRACT FROM AUTHOR]

为了响应乡村振兴、精准扶贫等一系列农村相关政策, 通过分析了解温州市村级居民点的空间分布特征, 对村级居民 点适宜度做出分级评价, 以温州市为例为村级居民点的布局优化提供一定的参考。通过地理空间数据云、Python 结合天地图与 高德地图提供的接口, 获取温州市道路路网数据、水系水网数据、DEM 数据、AOI 地类数据、村级居民点数据。利用泰森多边 形、核密度、近邻性分析方法, 分析温州市村级居民点的空间分布特征及其影响因子, 并利用物元模型方法对温州市村级居民 点的适宜度进行分级评价。温州市的村级居民点主要高密度地分布在中部沿海地区, 在自然因素的角度上, 其分布主要受到高 程的影响, 在社会因素上, 村级居民点分布密集程度跟道路的距离成反比, 而温州市村级居民点的适宜度整体较高, 最佳适宜 村级居民点占村级居民点总数的 73.83%。温州市的村级居民点在自然因素和社会因素的共同影响下, 受自然因素影响较大, 其 中以地形因素为主。温州市的村级居民点整体适宜度较高, 适宜居住, 研究可以为优化温州市村级居民点的布局提供一定的参 考价值, 拓展村级居民点的分析思路。 [ABSTRACT FROM AUTHOR]
