“一带一路”港口城市及其周边区域土地覆盖分类数据集

东亚区和东南亚区港口城市周边主要土地覆盖类型为森林和农田，其次为不透水层。其中，釜山、关丹城市周边的森林面积比例较高，均达到70%以上（分别为70.78%和93.16%），上海和曼谷城市周边的农田面积比例较高，分别为49.38%和79.79%，而不透水层面积比例较高的有新加坡、上海和曼谷，分别为36.82%、29.89%和15.62%。从城市周边生态环境状况看，东亚区上海周边以农田为主，釜山周边以森林为主；东南亚区港口城市周边主要是森林，其次是农田；南亚区港口城市周边主要是农田，其次是森林；西亚区港口城市周边主要是裸地；欧洲区的里斯本周边以农田为主，而圣彼得堡周边以森林为主；非洲-地中海区欧洲部分的港口城市周边多以农田为主，其次为森林和草地；大洋洲区的悉尼周边以森林为主，达尔文周边以草地为主，其次是森林

The main land cover types around port cities in East Asia and Southeast Asia are forests and farmlands, followed by impervious surfaces. Specifically, the areas around Busan and Kuantan boast relatively high forest coverage rates, both exceeding 70% (70.78% and 93.16% respectively). The areas around Shanghai and Bangkok have relatively high proportions of farmland, accounting for 49.38% and 79.79% respectively, while the areas around Singapore, Shanghai and Bangkok have relatively high impervious surface coverage, at 36.82%, 29.89% and 15.62% respectively. From the perspective of the ecological environment around the cities: the area around Shanghai in East Asia is dominated by farmlands, while that around Busan is dominated by forests; port cities in Southeast Asia are mainly surrounded by forests, followed by farmlands; port cities in South Asia are mainly surrounded by farmlands, followed by forests; port cities in West Asia are mainly surrounded by bare land; in Europe, the area around Lisbon is dominated by farmlands, while that around Saint Petersburg is dominated by forests; port cities in the European part of the Africa-Mediterranean region are mainly surrounded by farmlands, followed by forests and grasslands; in Oceania, the area around Sydney is dominated by forests, while that around Darwin is dominated by grasslands, followed by forests.

背景概述

该数据集聚焦'一带一路'沿线港口城市及其周边区域的土地覆盖分类，覆盖东亚、东南亚、南亚、西亚、欧洲、非洲-地中海和大洋洲等多个区域，详细分析了森林、农田、不透水层等主要土地覆盖类型的比例分布。数据集通过对比不同城市（如上海、釜山、曼谷、新加坡等）的生态环境状况，揭示了区域间土地覆盖的显著差异，例如东亚区以农田和森林为主，东南亚区森林占优，而西亚区则以裸地为特征，为研究'一带一路'区域生态环境和土地利用提供了关键数据支持。
